AC500-XC
Technical data

Analog/digital mixed I/O expansion module
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 bit + sign; 0…10 V, 0…20 mA, 4…20 mA: 12 bits.
