17.2.1 DESCRIPTION
The Solid-State Relay I/O module provides two solid state inputs and one electro-mechanical output.
This I/O module is available in three versions as follows:
Input Voltage Assembly No.
48V or 125V (106435-3)
250V (106435-4)
5V (106435-5)
The inputs are used for keying trips, and the output is used as an acknowledgement that a trip was sent
(trip sent). The electro-mechanical output has N.O. and N.C. connections at the terminal block. All
signals to and from the Solid-State Relay I/O module interface directly with the 9780 Logic Module.
The 48/125V version requires that jumpers J4 and J5 be configured for the input voltage requirement.
They are placed in the 48V or 125V position as applicable. The 250V version does not have these
jumpers installed.
The Solid-State Relay I/O module is primarily used for TX only applications. It can also be used for
customer specific applications and can be mounted in a spare I/O slot, if available, or in an expansion
chassis.
