SCC Configuration Guide SCC – Portable, Low-Cost Signal Conditioning • Ideal for portable measurement systems • Wide variety of direct signal and sensor connectivity options • Wide range of analog and digital conditioning options • Measurement type selectable on a per-channel basis • Front-end signal conditioning for M Series, E Series, and some B Series multifunction DAQ devices Configure Your SCC System in Six Steps Step 1 – Select Your SCC Modules (Table 1) Analog input, analog output, and digital I/O modules have dedicated slots. You can select up to eight noncascaded modules for analog input and eight modules for digital I/O. You can install feedthrough modules in any slot, but they are especially useful for accessing counter/timers on your M Series, E Series, or B Series multifunction DAQ device. Step 2 – Choose an SCC Carrier (Table 2) SCC carriers are available either with a hinged lid or with configurable connectors using panelettes. Hinged lids provide quick access to the modules. Configurable connectors provide custom signalinterface options. Step 3 – Select Your Panelettes (Table 3) If you have chosen an SCC carrier with configurable connectors, you can also select connector and interface panelettes. Different carriers offer different numbers of panelette slots. Also, some panelettes occupy more than one slot. Step 4 – Determine Your Power Option (Table 4) You can power an SCC system using a +5 VDC, 120/240 VAC, or 7 to 42 VDC external power source. To indicate the power option for your SCC system, select 01, 02, or 03 as the last two digits of the part number of the SC-2345 or SC-2350 carrier. Please note that if you choose power option 01, it is possible to power your SCC system using the internal power source of your DAQ device. For DAQCard and DAQPad devices, the total power required by your SCC modules must be less than 800 mW (490 mW of analog power). For PCI or PXI and M Series or E Series multifunction DAQ devices, the total power required by your SCC modules must be less than 4.55 W (1.74 W for analog modules). Additional power modules are sold separately. To determine the power requirements of the modules in your SCC DAQ system, use the online SCC Advisor at ni.com/advisors. Step 5 – Select Your DAQ Device and Cable (Table 5) Select the DAQ device to control your system. Step 6 – Select Your Accessories Choose from rack/panel-mount kits and stacking kits. You can also select additional power kits separately if your application requires multiple power configurations.

Each independent channel of the NI SCC-CI20 includes a precision 249 Ω current conversion resistor that converts a 0 to 20 mA signal into a 0 to 5 V signal. Each channel includes a differential instrumentation amplifier with low-impedance outputs for maximum scanning rates by the multifunction DAQ device, and bias resistors for handling both floating and ground-referenced current sources. The SCC-CI20 also includes two spare 249 Ω resistors. When you install the SCC-CI20 in the SC-2345, the carrier routes the two output voltages to two input channels of the DAQ device, channels x and x+8, where x is 0 through 7. For example, if you install the module in the J1 socket of the SC-2345, the output voltages are routed to input channels 0 and 8 of the DAQ device.

This module is installation rated for CAT I, and provides a safe working voltage of 60 VDC. Because the modules are isolated, you can connect two NI SCC-CO20 modules in parallel to provide up to 40 mA. The SCC-CO20 plugs into either analog output socket, J17 or J18. The voltage applied to the module from an analog output channel of a multifunction DAQ device sets the current output. Because there are two output channels on DAQ devices, there are a maximum of two SCC-CO20 modules per carrier. Note: Use the SCC-CO20 with only multifunction DAQ devices that have analog outputs. Channel 1 Description Isolated digital input Part Number 777459-11 The National Instruments SCC-DI01 is a single-channel, optically isolated digital input module for sensing digital signals up to 30 VDC, including TTL. This digital input module can sense both AC and DC signals and has a status LED for visual verification of the module input status. The NI SCC-DI01 fits in any SC-2345 socket J9 through J16. When you install an SCC-DI01 in one of these sockets, the digital signal is automatically routed to a DIO line of the multifunction DAQ device. For example, socket J9 connects to digital line 0 of the data acquisition device. Because you can configure multifunction DAQ devices for input or output on a line-by-line basis, you can have between one and eight SCC-DI01 modules per carrier.

The NI SCC-DO01 optical isolation circuitry handles up to 24 VDC and includes a status LED for visual verification of the module output status. The SCC-DO01 includes an external switch with which you can configure the power-up state of the module either high or low. The SCC-DO01 plugs into any SC-2345 socket between J9 and J16. When you install the module in one of these sockets, the digital signal is controlled by a DIO line of the multifunction DAQ device. For example, socket J9 connects to digital line 0 of the DAQ device. Because you can configure DAQ devices for input or output on a line-by-line basis, you can have from one to eight SCC-DO01 modules per carrier. The National Instruments SCC-RLY01 is a single-channel relay module for switching external devices. It contains one single-pole, double-throw (SPDT) relay capable of switching 5 A at 30 VDC or 250 VAC when used with the SCC-68 and 5 A at 30 VDC or 30 VAC when used with the SC-2345. The NI SCC-RLY01 uses positive logic. A digital high sets the relay, and a digital low resets it. The SCC-RLY01 plugs into any SC-2345 socket between J9 and J16. When inserting an SCC-RLY01, a DIO line of the multifunction DAQ device controls the digital signal. For example, socket J9 connects to digital line 0 of the data acquisition device. Because you can configure the DAQ devices for input or output on a line-by-line basis, you can have from one to eight SCC-RLY01 modules per carrier.

For analog input channels, you can connect to either two single-ended or one differential channel. The NI SCC-FT01 includes a breadboard area for development of custom signal conditioning circuitry. If you install the SCC-FT01 in an analog input socket (J1 through J8, SC-2345 or SC-2350) or analog output socket (J17 or J18, SC-2345 only) then you have direct connection to the corresponding channels of the DAQ device. You can add custom conditioning to the SCC-FT01 for these analog inputs or outputs. In any socket, the SCC-FT01 module has access to 5 and ±15 VDC power. If you use the breadboard area for custom conditioning, you can cascade the SCC-FT01 with other SCC modules for dual-stage conditioning.
