The Allen-Bradley 1746-IA16 digital input module is a member of the SLC-500 family of processors. The 1746-IA16 has 16 input points and operates with a voltage category of 100V or 120V AC input signal. The 1746-IA16 has 16 points per common and its operating voltage is 85-132V AC at 47-63Hz. In addition, the 1746-IA16’s backplane current consumption is 0.085A at 5V DC and 0A at 24V DC.
The maximum signal delay for the ON and OFF states is 35ms and 45ms, respectively. The 1746-IA16’s maximum off-state voltage is 30V AC, its maximum off-state current is 2mA, and its input current is 12mA at 120V AC nominal. The maximum inrush current for the 1746-IA16 is 0.8A while the maximum inrush current time lasts for 0.5ms.
You can use a current limiting resistor for limiting the inrush current. This resistor will change the operation of the 1746-IA16 AC module. AC input devices, e.g. the 1746-IA16, needs to be compatible with the SLC-500 input circuit inrush current. It operates optimally at temperatures between 0 and 60 degrees Celsius.
Dimension wise, the 1746-IA16 measures 13cm x 5cm x 15cm. The 1746-IA16 is manufactured for use with programmable controllers. It is KCC, MARINE-ABS, C-Tick, MARINE –BVS, MARINE GL, MARINE –LR, CE marked and MARINE –DNV-certified.
The 1746-IA16 is intended for mounting on a chassis which has an open enclosure. It has a 500 VDC isolation on communication channels and 1500V AC backplane isolation. At 10-2000Hz, the 1746-IA16’s vibration rating is 1G.

About 1746-IA16
The Allen-Bradley 1746-IA16 SLC 500 Discrete Input Module is a 16-channel digital input module from the Allen-Bradley SLC 500 PLC series. This module comes with sixteen 120 Volts AC-rated input circuits that can interface with 120/240 Volts AC voltage levels. It comes with 16 individually isolated input circuits arranged in a single group of 16 inputs with an individual common for each input point. Each input circuit is capable of receiving a 100/120 Volts AC input signal, and each circuit has an operating input voltage range of 85 to 132 Volts AC at 47 to 63 Hertz. The 1746-IA16 input module draws 0.85 Amps of maximum backplane current at 5 Volts DC. It has a maximum off-state voltage rating of 30 Volts AC and a maximum off-state current rating of 2 milliamps. Each of the 1746-IA16 Discrete Input Module’s input points has a nominal input current rating of 12 milliamps at 120 Volts AC and a maximum inrush current rating of 0.8 Amps for 500 milliseconds.
The Allen-Bradley 1746-IA16 Discrete Input Module has a self-lifting pressure plate terminals that accept 14 AWG wires, and like all SLC 500 I/O modules, it comes with built-in input filtering, isolation, and surge protection to enhance its operation even in noisy environmental conditions. The module also features input filtering, optical isolation, and built-in surge protection to enhance its reliability of operation in noisy industrial environments. The 1746-IA16 Discrete Input Module has 16 LEDs on the front which indicate the status of each input point, and beneath the module is a terminal identification diagram that aids in terminal identification. The 1746-IA16 Discrete Input Module is supplied with a color-coded removable terminal block that allows the operators to easily remove or insert modules without having to rewire the terminals.
