1 INTRODUCTION For Your Notes 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. The CIO-RELAY32 is two CIO-RELAY16s on a single board while the CIO-RELAY24 is are CIO-RELAY32 with eight of the relays not installed. The /M versions (e.g.

6 SPECIFICATIONS 2.2 Run InstaCalTM To run InstaCalTM in the various forms of Windows, find the file named InstaCal.exe using your file management system and double click your mouse on it. In DOS simply type instacal and press the Enter key. 6.1 CIO-RELAY08, 16, 24 and 32 (standard versions) Once running, InstaCalTM provides four sub-menus (plus exit). 1. Select Install (either highlight it and hit enter of double click your mouse on it).
5.2 FORM C RELAYS (standard versions) 3 HARDWARE INSTALLATION Shown here is the schematic for a form C relay as used on the standard CIORELAY08, 16, 24 and 32. 3.1 Mercury whetted (/M) board special considerations The Mercury whetted boards must be mounted in the computer such that they will remain within 30 degrees of vertical. Note that installation of these boards in most tower computer cases will require the tower be rested on its side for proper operation. 3.

5 CONNECTING TO RELAYS 5.1 I/O CONNECTOR DIAGRAMS The CIO-RELAY08 and CIO-RELAY16 boards use a single 50 pin connector for signal interfacing. The CIO-RELAY24 and CIO-RELAY32 use two 50 pin connectors. The pin-outs of the connector are shown here.
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 OP7 OP6 OP5 OP4 OP3 OP2 OP1 OP0 HEX 80 40 20 10 8 4 2 1 ON = 1 1 0 1 0 1 0 1 1 WEIGHT 80 0 20 0 8 0 2 1 AB DECIMAL 128 64 32 16 8 4 2 1 ON=1 1 0 1 0 1 0 1 1 WEIGHT 128 0 32 0 8 0 2 1 171 4.3 DETAILED RELAY CONTROL I/O MAP The following section provides a detailed description of the register map and relay control registers.
