The Allen-Bradley 1769-IA16 is a CompactLogix module, each channel operating at 120 Volt AC. It has Sixteen (16) points functioning as digital input module.

The channels present in this module form a single group and have internally-connected commons. The 1769-IA16 has a voltage category of 100 to 120 Volts AC and an operating voltage range of 79 to 132 Volts AC, with a line frequency of 47 to 63 Hertz. When in an off-state, this module has a maximum current of 2.5 mA and a maximum voltage of 20 Volts AC. During an on-state, the module’s minimum voltage is 79 Volts AC, the minimum current is 5 mA at 74 Volts AC, and the maximum current is 12 mA at 120 Volts AC. The maximum input impedance of the 1769-IA16 module is 12 kOhms at 50 Hertz and 10 kOhms at 60 Hertz, while its maximum inrush current is 250 mA. This module also has a maximum heat dissipation of 3.3 Watts, thermal dissipation of 2.7 BTU/hour, and a current draw of 115 mA at 5.1 Volts. The input delays of this module are 20 ms for both the On and the Off states.
The 1769-IA16 is an AC Digital I/O module requires a removable terminal block. This terminal block provide connections to I/O sensors and actuators. It is equipped with finger-safe covers. The I/O wiring for 1769-IA16 can be configured from beneath the module out to the I/O terminals. The removable terminal blocks ease this wiring process. The power supply distance rating of the 1769-IA16 module is 8 modules and the compatible power supply modules are the 1769-PA2, the 1769-PB2, the 1769-PA4, and the 1769-PB4. It comes with an open-style enclosure type rating and it is mounted using a panel mount or DIN rail mount. The approximate dimensions are 4.65 x 1.38 x 3.43 inches the module’s weight is 0.61 pounds or 280 grams. Note that the height of this module increases to 5.43 inches when used with mounting tabs. The 1769-IA16 is also an electronically-protected module.

The Allen-Bradley 1769-IA16 is a 1769 Compact I/O module that is used with 1769 CompactLogic controllers and MicroLogix 1500 controllers. This discrete input interface module features a single group with internally connected commons, composed of Sixteen (16) 100-120 VAC input channels. This module is primarily used to interface with field devices that operate in binary or ON/OFF mode such as switches, auxiliary contacts, sensors and other devices that generate or may pass through an AC signal.
The 1769-IA16 is compatible for with MicroLogix 1500 and CompactLogix controllers systems.

When configured in CompactLogix system, the power supply distance rating of the module must be observed. For the 1769-IA16, the power supply distance rating is Eight (8). If more than 8 modules are required, the module positioned outside the power supply distance rating must be installed after an additional system power supply or to a CompactLogix I/O bank. In a MicroLogix 1500 controller, the module is installed after the base module or to any adjacent module.

Compatible power supply for the 1769-IA16 includes 1769-PA2, 1769-PB2, 1769-PA4 and 1769-PB4. The module’s on state voltage is 79V AC.
