Model SRC-8
Addressable 8-Output Relay Module
OPERATION
The Model SRC-8 module from Siemens
Industry, Inc., used with the SXL-EX System is
an 8-Output Programmable Relay Module that
provides eight Form C relays. Terminal Block 9
(See Figure 1 below) provides a connection to
TB3 on the Main Board for a 24V regulated and
filtered power supply. Terminal blocks 1-8
provide the eight Form C relays.
If the green LED (labeled DS1) on the right-
hand side of the module is on, it indicates that
the module is active.
The SRC-8 causes a trouble on the display
panel when any of the following three conditions
occurs:
1. There is a short on the data line.
2. No SRC-8 module is connected to the
System, though there is an address for the
module in the System.
3. An SRC-8 module is connected to the
system, but there is no address for it in the
System.
