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.
