3.3 WAIT STATE

There is a wait state jumper on CIO-RELAY series boards. The factory default is wait state disabled. You will probably never need the wait state because PC expan- sion slot busses are limited to 8 or 10 MHz.

If you were to get intermittent operation from your CIO-RELAY board, you may try enabling the wait state to see if that solves the problem.

CIO-RELAY24 and CIO-RELAY32 Connector

This connector is the center of the board. The connector for relays 0 through 15 is the connector that is closest to the computer back-plate. PINS corresponding to relays 24 through 31 are not connected on the RELAY24 version.

The form A relays used on the /M versions have NO and COM connections only!

WARNING!

High voltages will be present on the CIO-RELAY boards when you have connected high voltage inputs or outputs to the CIO-RELAY connector. Use extreme caution! Never handle the CIO-RELAY when signals are connected to the board.! DO NOT REMOVE

THE PROTECTIVE PLATES FROM THE CIO-RELAY.
