APCI-RELAY8/IN8
Introduction
The APCI-RELAY8/IN8 is a 32-bit PCI local BUS board which provides 8 changeover relays and 8 opto
isolated digital input signals. Each relay has a power rating of 60W (resistive load). This allows
switching of voltages up to 48V DC (to meet low voltage directive) and currents of up to 1.0A.

Getting Started
•
•
•
•
Power down your PC system.
Install the board in a spare PCI Slot (See Installation for CE compliance).
Power up system with MSDOS.
Run APCI.EXE (supplied on the utility disk), this will search for the board and check I/O access. If
this fails, check board is correctly l0cated.
Warning
This board contains CMOS devices which may be damaged by static electricity. Please ensure antistatic precautions are taken at all times when handling this board. If for any reason this board is
returned to Arcom Control Systems, please ensure it is adequately packed to prevent damage during
shipment.

Operation
PCI Bus Interface
The PCI bus is a high speed alternative to ISA bus, it has been designed to overcome some of the
limitations of ISA bus, and provide faster throughput for I/O intensive peripheral devices. PCI bus
also supports Plug and Play configuration which allows the system software to allocate resources
during initialisation helping to overcome resource conflicts, which might exist in a system.
The APCI-RELAY8/IN8 uses a single chip PCI bus slave controller which is designed and
manufactured by PLX Technology. This device has been designed to fully support the PCI 2.1
specification and provides plug and play software capabilities. During power-up initialisation the PCI
BIOS will detect the card and assign a unique I/O address location and interrupt line. This ensures
that there are no resource conflicts on the PCI bus. Multiple cards are supported through this
mechanism without the need for address decode links.
The PLX device contains a standard type 00H configuration space header. The table below shows the
registers within this header which are required for configuration of the APCI-RELAY8/IN8.

Relays
When the board is switched ON, all relays are in the normally closed position. To swicth a relay ON
(i.e. change to normally open position) a logic ‘1’ must be written to the corresponding bit in the
relay output register. This will have no effect until a logic ‘1’ is written to bit 0 of the relay enable
register. For system initialisation, it is recommended that the output register is written with the
required relay states before the relay enable bit is set.
A relay status register has been incoporated in the design to enable reading of the relay outputs. If
a bit in this register is set to logic ‘1’ the corresponding relay is in the N.O position.
Relay Configuration
Opto Isolated Inputs
The status of the opto isolated inputs can be read via the opto input register. If the input is switched
ON (i.e. a voltage has been applied to the input line) the corresponding bit in this register is set to
logic’0’. A voltage in the range 10-30V must be applied to the input to ensure it is switched ON. Each
opto-isolated input has an optional debounce circuit which can be enabled/disabled via LK1.

I/O Map
The APCI-RELAY8/IN8 uses two consecutive I/O address locations to access the onboard functions.
The I/O base address is set by the PCI BIOS during initialisation (refer to the PCI BUS section of this
manual for details). A PCI BIOS function call may be used to determine the base address once the
system has been initialised. Multiple boards may be used in a system as each will be given a unique
I/O address.
