Description
Carries all internal signals between modules in a termi-
nal. The size of the module depends on the size of the
case.
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.
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.
The module consist of LED:s, a LCD, push buttons
and an optical connector for a front connected PC
Module for protection algorithm processing. Carries up
to 12 digital signal processors, performing all measur-
ing functions.
Description
Module with 8 optically isolated binary inputs, 10 out-
puts and 2 fast signalling outputs.
Modules used for digital communication to remote ter-
minal.
Used for galvanic separation of voltage and/or current
process signals and the internal circuitry.
Used for analog to digital conversion of analog pro-
cess signals galvanically separated by the TRM.
Used for SPA/LON/IEC communication
