CONTACT CLOSURE OUTPUT CONNECTIONS
Contact closure output connections are made via terminal blocks attached to the right side of the unit.
Please note that the three Channel 1 output connections begin at the second terminal screw closest to
the fiber connection on each of the three nine pin terminal strips. Channels 2 through 8 connections
continue down the terminal strip. Each channel has one common output connection that can be used
with a normally closed connection or a normally open connection. For optimum performance the copper
cables carrying the contact closure signal should be the shortest length of wire practical.
The supervised contact input at the transmitter will open the receiver’s corresponding contact if the
input is contact open, if the transmitter input is opened or shorted. For power loss the contacts may
reset or remain latched. See the Latching Select Switch section following. For configuring the
transmitter supervised inputs, see the transmitter instruction manual.
