MC-TDIA72 | 51303930-150 Honeywell Digital Input

120 Vac Digital Input with removable-screw terminals(1) The Optimal Replaceable Unit (ORU) is the object that can be replaced on a failure that minimally impacts the operation of the system. The ORU is generally an item that can be replaced in the field using a minimum number of tools. In many cases the item is plug replaceable such as the IOP.(2) Readback check coverage for the redundancy option is not equivalent. See Output Readback Check.(3) Compression-type relay FTA for DO-32 has 1 fuse per 2 points. Screw type relay FTA for DO-32 has 1 fuse per 8 points. Current overload protection for the DO16 is provided on a per channel basis based on the particular FTA used.(4) All Outputs are galvanically isolated from system common.(5) The output state upon failure of both the DO16 and DO32 IOP is configurable to either Hold or Unpower the output. The DO32 outputs are set to Unpowered when the on-board power regulator (5 V) has failed.(6) The output state upon failure of the PMM (or APMM or HPMM) for both DO16 and DO32 IOPs is configurable to either Hold or Unpower the output.(7) The DO32 performs register readback check on the IOP. The DO16 performs actual output readback check including the FTA and FTA cable.(8) DO16 FTA types are: 120 Vac Electro-Mechanical Relay; 240 Vac Electro Mechanical Relay; 24 Vdc @100 ma Non-Isolated; 20-200 Vdc Solid State; 3 30 Vdc Solid State; 120/240 Vac Solid State; 31-200 Vdc Solid State
