The A1 code selects the standard-environment unit and B02 selects 1 V/mA conversion for current-output equipment such as IPC-series or VE210 arrangements. The unit clips to TH35 rail and uses separate sensor-side, power and monitor-side terminal groups.
Important Notice: Confirm the complete A1-B02 option code, 18 to 30 VDC supply, TH35 mounting, removable terminal assignments, sensor type and current output, monitor voltage input, cable shields, B02 1 V/mA scaling, zero setting and controlled channel-response test before commissioning.
