Page 3: Introduction
The CIO-RELAY16 is a 16 channel relay interface board for ISA bus computers. The board provides 16 Form C (SPDT) relays. The CIO-RELAY08 board is designed for applications that require fewer relays and is identical to the RELAY16 board except that only 8 relays are installed. -

5 CONNECTING TO RELAYS 5.1 I/O CONNECTOR DIAGRAMS The CIO-RELAY08 and CIO-RELAY16 boards use a single 50 pin connector for sig- nal interfacing. The CIO-RELAY24 and CIO-RELAY32 use two 50 pin connectors. The pin-outs of the connector are shown here. -
Page 9: Programming Notes
For example, to assemble the control byte that will turn on relays 0. 1. 3. 5 and 7 we can see from the chart below we need to write decimal 171 (hex AB): RELAY ON = 1 WEIGHT DECIMAL 4.2 PROGRAMMING NOTES WRITE = CONTROL: Write a byte to the register to control the relays.
