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 sin- gle board while the CIO-RELAY24 is are CIO-RELAY32 with eight of the relays not installed. The /M versions (e.g. CIO-RELAY16/M and CIO-RELAY0

Throughout this manual we use CIO-RELAY as a generic designation for the CIO- RELAY08, CIO-RELAY16, CIO-RELAY24 and CIO-RELAY32. When required due to the differences in the boards, the specific board name is used. GENERAL SPECIFICATIONS The CIO-RELAY boards are easy to u
