'HVFULSWLRQ
Backplane module
Carries all internal signals between modules
in a terminal.
Analog input module (AIM)
Used for analog to digital conversion of ana-
log processing signals galvanically separated
from the internal circuits.
Numerical module (NUM)
Fits into the specific system slot in the back-
plane. The module may carry a mezzanine
card, according to the PMC standard.
Power supply module (PSM)
DC/DC converter that support the electronics.
The module can provide up to 50W. Supervi-
sion of all voltages is implemented. The mod-
ule includes one relay output for the “internal
failure” signal.
Human machine interface (LCD-HMI)
The module consists of LEDs, an LCD, push
buttons and an optical connector for a front
connected PC.
