17.4.1 DESCRIPTION
The Solid-State Input/Output I/O module provides two solid-state inputs, two solid-state outputs, and
one electro-mechanical output. This I/O module is available in three versions as follows:
Input Voltage Assembly No.
48V or 125V (106445-3)
250V (106445-4)
5V (106445-5)
In general, the inputs are used for keying trips, the solid-state outputs are used for receiving trip and
guard commands, and the electro-mechanical 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 Input/Output 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.
The Solid-State Input/Output I/O module is primarily used for TX/RX 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.
