Allen Bradley 1746-IM16 SLC I/O Digital Modules

The 1746-IM16 SLC 500 Digital AC Input Module by Allen-Bradley is an input (AC) module with sixteen 200-240V AC inputs and is fitted into any available SLC 500 I/O chassis using an RTB (Removable Terminal Block). It has 16 points per common and an input operating voltage of 170-265V AC at 47-63Hz. It has a backplane current rating of 0.085A at 5V DC and an electrical signal delay of 35ms for ON and 45ms for OFF state around its input points. It has an OFF-state rating of 50V AC voltage loss and 2mA maximum OFF-state current. The 1746-IM16 has an input current (nom) of 12mA around each input points and has a maximum surge current of 1.6A, which can last for a maximum duration of 0.5ms. It has a maximum power dissipation of 0.35W at each point and the total heat dissipated by the module is at 6W. It provides voltage isolation between input terminals and control logic tested at 1500V and is NEMA standard ICS 2-230-rated for noise immunity. The operating temperature of the 1746-IM16 ranges between 0 and 60 ?°C (32 and 140 ?°F) at 5-95% non-condensing humidity limits and it has a non-operational storage temperature of -40 and 85 ?°C (-40 and 185 ?°F). The 1746-IM16 has an operational shock withstand of 30G and can sustain an operating 2.5G vibration at 57-200Hz.
