Digital data format
16 significant bits out of 16 bits are available; in 2’s complement
Isolation
Optical coupler isolation between analog circuits and digital circuits. No
isolation among analog channels.

Protection
Voltage output is protected from short circuits. However, short circuit
conditions lasting for too long may cause damage to the internal circuits.
Current output can be open circuit.
Series connection to
ELCM controllers
The modules are numbered from 0 to 7 based on their position with respect to
the controller. Max. 8 modules are allowed per controller
