Backplane module
Carries all internal signals between modules in
a terminal. The size of the module depends on
the size of the case.
1/1x19”: 13 slots available for I/O.
3/4x19”: 8 slots available for I/O.
1/2x19”: 3 slots available for I/O.
Power supply module (PSM)
Including a regulated DC/DC converter that sup-
plies auxilary voltage to all static circuits.
•
For case size 1/2x19” and 3/4x19” a version
with four binary inputs and five binary outputs is
used. One of the five outputs is reserved for the
internal fail alarm.
•
For case size 1/1x19” a version without
binary I/O:s and increased output power is
used. An internal failure alarm output is avail-
able.
Main processing module (MPM)
Module for overall application control. All infor-
mation is processed or passed through this
module, such as configuration, settings and
communication.
Human machine interface (LCD-HMI)
The module consists of LED:s, a LCD, push but-
tons and an optical connector for a front con-
nected PC

vanically separated channels.
Binary input module (BIM)
Module with 16 optically isolated binary inputs
Binary output module (BOM)
Module with 24 single outputs or 12 double-pole
command outputs including supervision function
Binary I/O module (IOM)
