Module
Description
Backplane module (BPM)
Carries all internal signals between modules in a termi-
nal. The size of the module depends on the size of the
case.
Power supply module (PSM)
Including 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 used.
An internal fail alarm output is also available.
Main processing module (MPM)
Module for overall application control. All information is
processed or passed through this module, such as
configuration, settings and communication. Carries up
to 12 digital signal processors, performing all measur-
ing functions.
Human machine interface (LCD-HMI)
The module consist of LED:s, a LCD, push buttons
and an optical connector for a front connected PC
Signal processing module (SPM)
Module for protection algorithm processing. Carries up
to 12 digital signal processors, performing all measur-
ing functions.
Module
Description
Binary input module (BIM)
Module with 16 optically isolated binary inputs
Binary output module (BOM)
Module with 24 single outputs or 12 double-pole com-
mand outputs including supervision function
Transformer input module (TRM)
Used for galvanic separation of voltage and/or current
process signals and the internal circuitry.
A/D conversion module (ADM)
Used for analog to digital conversion of analog pro-
cess signals galvanically separated by the TRM.
Serial communication module (SCM)
Used for SPA/LON/IEC communication
