Communication interface modules
For all modules: max cable length for connected process signals is 1000 m for shielded cable and 600 m
for unshielded ones. For all Input modules, the signal resolution for channel configuration is:
-10…+10 V: 12 bits + sign; 0…10 V, 0…20 mA, 4…20 mA: 12 bits. Temperature: 0.1 °C.
