The Advantech PCI-1762 DAS card is a 16-ch relay actuator and 16-ch isolated digital input card for the PCI bus. Its sixteen on-board SPDT relays are ideal for applications such as device ON/OFF control or small power switched. For easy monitoring, each relay is equipped with one red LED to show its ON/OFF status. The PCI-1762’s sixteen optically-isolated digital input channels are ideal for digital input in noisy environments or with floating potentials. 1.1.1 PCI-1762 16-ch Isolated Digital Input and 16-ch Relay Output Card The following sections of this chapter will provide further information about features of the DAS cards, a Quick Start for installation, together with some brief information on software and accessories for the PCI-1762 card. 1.2 Features 16 relay output channels and 16 isolated digital input channels LED indicators to show activated relays Jumper selectable Form A/Form B-type relay output channel Output status read-back Keep relay output values when hot system reset High-voltage isolation on input channels (2,500 VDC) High ESD protection (2,000 VDC) High over-voltage protection (70 VDC) Wide input range (10 ~ 50 VDC) Interrupt handling capability High-density DB-62 connector Board ID The Advantech PCI-1762 offers the following main features: Robust Protection The PCI-1762 digital input channels feature a robust isolation protection for industrial, lab and machinery automation applications. It durably withstands voltage up to 2,500 VDC, preventing your host system from any incidental harms. If connected to an external input source with surge-protection, the PCI-1762 can offer up to a maximum of 2,000 VDC ESD (Electrostatic Discharge) protection. Even with an input voltage rising up to 70 VDC, the PCI-1762 can still manage to work properly albeit only for short period of time. Wide Input Range The PCI-1762 has a wide range of input voltage from 10 to 50 VDC, and it is suitable for most industrial applications with 12 VDC, 24 VDC and 48 VDC input voltage. Board ID The PCI-1762 has a built-in DIP switch that helps define each card’s ID when multiple PCI-1762 cards have been installed on the same PC chassis. The board ID setting function is very useful when users build their system with multiple PCI-1762 PCI-1762 User Manual 2 Reset Protection Fulfills Requirement for Industrial Applications When the system has undergone a hot reset (i.e. without turning off the system power), the PCI-1762 can either retain outputs values of each channel, or return to its default configuration as open status, depending on its on-board jumper setting. This function protects the system from wrong operations during unexpected system resets. 1.3 Applications Industrial On/Off control Switch status sensing Digital I/O control Industrial and lab automation SMT/PCB machinery Semi-conductor machinery PC-based Industrial Machinery Testing & Measurement Laboratory & Education External relay driving 1.4 Installation Guide Before you install your PCI-1762 card, please make sure you have the following necessary components: PCI-1762 card PCI-1762 User's Manual Driver software - Advantech DLL drivers (included in the companion CD-ROM) Wiring cable - PCL-10162 (optional) Wiring board - ADAM-3962 (optional) PC or workstation with a PCI-bus slot (running Windows XP/Vista/7) Application software - ActiveDAQ Pro or other 3rd-party software After you get the necessary components and maybe some of the accessories for enhanced operation of your Multifunction card, you can then begin the Installation procedures. 3 PCI-1762 User Manual Overview Plug-and-Play Function The PCI-1762 is a Plug-and-Play device, which fully complies with PCI Specification Rev 2.2.

Since register-level programming requires much effort and time, we recommend that you use the Advantech DLL drivers instead. However, if register-level programming is indispensable, you should refer to the relevant information in Appendix C, Register Structure and Format. PCI-1762 User Manual 6 Chapter 2 Installation 2 2.1 Unpacking After receiving your PCI-1762 package, please inspect ita contents first. The package should contain the following items: PCI-1762 card Companion CD-ROM (DLL driver included) Startup Manual 2.2 Switch and Jumper Settings The PCI-1762 card has one function switch and two jumper settings. The following sections tell how to configure the card. You may want to refer to the figure below for help in identifying card components. Figure 2.1 Card Connector, Jumper and Switch Locations PCI-1762 User Manual 8 Names of Jumpers Function Description JP4 ~ 19 Sets relay output to be normally open JP2 Keep last status after hot reset Default configuration Setting relay outputs to be NC/NO Sixteen relay outputs, K0 ~ K15, are single-pole single-throw (SPST), which can be jumper set as either normally open (NO) or normally close (NC) (see Table 2.2). The default settings for K0 ~ K15 are normally open. Table 2.2: Summary of jumper settings for relay Relay Output channel Corresponding Jumper K0 JP4 K1 JP5 K2 JP6 K3 JP7 K4 JP8 K5 JP9 K6 JP10 K7 JP11 K8 JP12 K9 JP13 K10 JP14 K11 JP15 K12 JP16 K13 JP17 K14 JP18 K15 JP19 Setting the time to reset the relay outputs Some users will want the capability of clearing each relay output when 9 PCI-1762 User Manual Installation Sets relay output to be normally closed Chapter 2 Table 2.1: Summary of Jumper Settings the system (or PC) issues a reset signal on the PCI bus. Some users will want to clear their relays only as part of system power-on. The PCI-1762 satisfies both these needs by providing jumper JP2. Depending on the application, this capability may allow relay outputs to be “OFF” without requiring a complete shutdown of processes controlled by the card. Complete loss of power to the chip clears the chip memory. Thus, no matter how JP2 is set, if the power to the PCI-1762 is disconnected, the relay initial power-on state will be “OFF” (NC or NO, depending on the user’s settings). 2.3 I/O Connectors IDI0 ~ IDI3 : Isolated digital input of Group 0 IDI4 ~ IDI7 : Isolated digital input of Group 1 IDI8 ~ IDI11 : Isolated digital input of Group 2 IDI12 ~ IDI15 : Isolated digital input of Group 3 ECOM0 : External common input of Group 0 ECOM1 : External common input of Group 1 ECOM2 : External common input of Group 2 ECOM3 : External common input of Group 3 NC : No connection Figure 2.2 I/O connector pin assignments for the PCI-1762 PCI-1762 User Manual 10 We recommend you install the driver before you install PCI-1762 card into your system, since this will guarantee a smooth installation process.

A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to the PCI-1762 via the I/O connector. 3.2 Isolated Digital Input Connections The PCI-1762 has 16 isolated digital input channels designated IDI0~IDI15. Each of isolated digital input channel accepts 10~50 VDC voltage inputs, and accept bi-directional input. It means that you can apply positive or negative voltage to an isolated input pin (Vin). The figure below shows how to connect an external input source to one of the card’s isolated input channels. Figure 3.1 Isolated Digital Input Connections PCI-1762 User Manual 18 After power on, the initial relay output status of PCI-1762 is shown as below: A write operation to I/O address, BASE +0, will change the output status of each relay. For example, if Bit 0 of BASE +0 is set "1" (logic high), relay 0, K0, will switch from position "NORMALLY CLOSED", NC0, to position "NORMALLY OPEN", NO0. This means that LOAD2 will be de-energized, while LOAD1 is energized. To summarize, the "COMMON" line connect to the "NORMALLY CLOSED" line, if the corresponding bit is set as 0 (power-on initial status). Otherwise, if the corresponding bit is set as 1, then the "COMMON" line will connect to the "NORMALLY OPEN" line. 19 PCI-1762 User Manual Signal Connections Figure 3.2 Relay Output Connection Chapter 3 3.3 Relay Connections PCI-1762 User Manual 20 Appendix A Specifications A A.1 Specifications Table A.1: Isolated Digital Input Number of Input Channels 16 Optical Isolation 2500VDC Opto-isolator response time 25μs Over-voltage Protect 70 VDC Input Voltage VIL (max.)
