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. There are Three (3) softwares thay may be used to configure the module depending on the controller used and firmware. If used with MicroLogix 1500, the programming software needed is RSLogix 500 as the MicroLogix 1500 controller is configured using this software. If used with CompactLogix controller, the required software is RSLogix5000 or Studio 5000. The specific software is determined by the firmware required. Whatever software is used, it permits access to the module’s configurable parameters such as module inhibition, packet interval, slot assignment and revision number. The module’s address registers such as input data files is accessed using any of the mentioned programming software.

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.
