Product Details

The AB 1771-IAD is a PLC 5 Digital AC/DC Input Module. It converts AC signals provided by user devices to the logic level needed by the processor. It controls the state of corresponding bits in the PLC data table and it contains various input devices such as pushbuttons, limit switches, pilot lights, motor starters, and annunciators to interface with on/off sensors and actuators. It provides a modular design with space-saving and pocket-friendly means to add input to a PLC control system. It comes with a 1771-WH wiring arm to replace the module, eliminating the need to disconnect the wiring. It is a series D module and supports ½, 1, and 2-slot I/O addressing.

The 1771-IAD module has 16 inputs with a 120V AC/DC voltage category. It has an operating voltage range of 79 - 138V AC or 79 - 138V DC. It has a typical signal delay of 5ms (±3) at on AC state, 3ms (±0.1) or 10ms (±1) at on DC state, and 25ms (±5) at off AC/DC state. It has a maximum Off-state current of 3mA for AC and 0.8mA for DC and a backplane current load of 195mA. It has a maximum power dissipation of 8.8W and a thermal dissipation of 30.1 BTU/hr. It is installed in a 1771 I/O chassis containing a PLC processor. Keying bands for putting it in the right slot are between pins 14 and 16 for the upper connector and between pins 10 and 12 for the lower connector.

The 1771-IAD module has 1 green module active indicator and 16 red status indicators for system logic side indication at the front panel. It contains optoelectrical isolation to protect the system circuits from electrical transients. It also contains input filtering feature to reduce electrical noise.
