Option Modules - ABB TZIDC Commissioning Instruction

TZIDC, TZIDC-110, TZIDC-120 DIGITAL POSITIONER | CI/TZIDC/110/120-EN REV. E

Option modules

Module for analog feedback AO*
Only for devices with HART® Communication.
Without any signal from the positioner (e.g. 'no power' or
'initializing') the module sets the output to > 20 mA (alarm level).
