1771-ID16K

The Allen-Bradley 1771-ID16K is a conformal-coated 120V AC/DC isolated 16-input module that is part of the 1771 Digital AC/DC Input Modules. Its conformal coating offers layers of protection from humidity and contaminants. It comes with the selectable input filter feature that suppresses voltage transients caused by contact bounces or by radiated electrical noise. This results in a boost in overall performance, improved power quality, optimized product life, and minimal downtime. To drive terminals using the 1771-ID16K 120V AC/DC Isolated Input, connect it to an AC output module. When using the 1771-OA, 1771-OD or the 1771-OP output; add a 2.5K ohm, 10W resistor between the output terminal and the common. To eliminate the need for a resistor, use the 1771-OD16 or the 1771-OAD 120V AC output module. This input is compatible with a 1771-A1B through 1771-A4B or later I/O chassis. It has a factory-set filter time of 9ms. Plus, its filter time jumpers can be set to normal or fast. The 1771-ID16K Digital Module ships with the 40 Terminal Field 1771-WN Wiring Arm.  It has an input voltage range of 74-138V AC at 47-63Hz and 105-138V DC with a nominal input voltage of 120V AC/DC. It has an on-state voltage range between a minimum of 74V AC, 105V DC and a maximum of 45V AC, 66V DC.
