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.

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 anti-
static 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.
