THE OPTOISOLATED INPUT MODULE PROVIDES OPTO-ISOLATED INPUT INTERFACES FROM:
Optoisolated Inputs
Optoisolated Inputs 52b, STUB Bus, Target Reset to logic level inputs on the Microprocessor module. This part
contains 3 identical circuits, jumper positions JMP7 to JMP9.
(1-2) are for 15/20 Vdc
(3-4) are for 48/125 Vdc
(5-6) are for 220/250 Vdc
Note: Position 3-4 is the factory setting.
Receiver Inputs
These inputs (SPACE 1, MARK 1, CHAN FAIL 1, SPACE 2, MARK 2, CHAN FAIL 2) interface to an external
communication receiver such as Power Line Carrier, Audio Tone, etc.
Jumper Positions
1-2
7-8
9-10
Note: Position 1-2 is the factory setting.
• Connector JA connects to the Backplane module and, via terminal block TB-5, to the exter-
nal contacts.
• Connector JB interfaces to the Microprocessor module via connector JB-4 (on the intercon-
nect module).
