Rockwell Automation / ICS Triplex T7481A is an evidence-bounded Regent Plus monitored guarded output module in the ICS Triplex installed-base context. The official Regent Plus reference identifies T7481A as the 24 VDC monitored guarded output module and distinguishes its 5 mA minimum load from T7481.
