Introduction

The PCI24 is an 8-bit ISA bus add-on board providing 24 opto-isolated digital inputs and 3 16-bit counter/timers. The board also provides 12V or 24V excitation for external devices from an isolated DC-DC converter. The 3 counter/timers are implemented using an 8254 device. Two of the counter/timers are cascaded to form a 32-bit counter. This is intended as a programmable interrupt generator. The output of this combined counter and that of counter 2 can be used to generate an interrupt on the PCbus. Safety , connectors, cabling, insulation and power dissipation limit the maximum input voltage to 40V relative to PC chassis GND.
