Z-3AO: 3-channel analog output module / RS485

Z-3AO is a ModBUS module for managing 3 analog outputs configurable in current or voltage with 12-bit resolution.

The full scale and start scale are programmable in voltage with ranges -10 ..10 V, 0 ..10 V or 2 ..10 V or in current at 0/4..20 mA or 4 ..20 mA.

Z-3AO ensures output isolation of 1500 Vac relative to the remaining low voltage circuits.

Outputs protected with 400 W/ms transient suppressors.
