Combined backplane module (CBM) The size of the module depends on the size of
the case.
Power supply module (PSM) Available in two different versions, each includ-
ing a regulated DC/DC converter that supplies
auxiliary voltage to all static circuits.
• For case size 1/2x19” and 3/4x19” a version
with four binary inputs and four binary outputs
are used. An internal fail alarm output is also
available.
• For case size 1/1x19” a version without
binary I/O:s and increased output power is
used.
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 consist of LED:s, a LCD, push but-
tons and an optical connector for a front con-
nected PC

Carries up to 12 digital signal processors, per-
forming all measuring functions.
Milliampere input module (MIM) Analog input module with 6 independent, gal-
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) Module with 8 optically isolated binary inputs,
10 outputs and 2 fast signalling outputs.
