Description
The Allen Bradley 1746-IB16 serves as an input module within the SLC 500 series, facilitating efficient digital communication. With the capability to manage 16 inputs, this module is configured for current sinking input types, which enable seamless integration in various control environments. The allowable operating voltage for this module ranges from 10V to 30V DC, making it versatile for different setups.
In terms of thermal performance, the module exhibits a total heat dissipation of 3.6 watts during operation. Each input channel specifically contributes 0.2 watts to heat generation, with a minimum baseline dissipation recorded at 0.425 watts. Notably, the backplane current consumption at 5V DC is measured at 0.05 amps, while at 24V DC, the consumption registers at 0 amps.

- North American Hazardous Location Approved
- SLC 500 Digital Input Module
- 24 VDC nominal input voltage
- Electrostatic Discharge Sensitive
The 1746-IB16 features a single input group with one common terminal and is intended for connection to sourcing field devices such as limit switches, proximity sensors, pushbuttons, selector switches, relay contacts, and solid-state output devices. Each input channel has a nominal input current of 8 mA at 24 VDC, with a maximum OFF-state voltage of 5 VDC and maximum OFF-state current of 1 mA, providing reliable digital signal detection under normal operating conditions.
The 1746-IB16 Allen-Bradley DC Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 1746-IB16 incorporates 8 ms ON-state and OFF-state input filtering, helping reduce false triggering caused by electrical noise or contact bounce. The module draws approximately 85 mA of backplane current at 5 VDC and provides 500 VDC isolation between the communication backplane and the input circuits. These characteristics allow the 1746-IB16 to operate reliably within the SLC 500 I/O system while maintaining electrical isolation from field wiring.
The 1746-IB16 installs directly into any available slot of a 1746 SLC 500 chassis and interfaces with field wiring through compatible removable terminal connections. The module communicates with the SLC 500 processor via the chassis backplane, allowing input status to be scanned and updated as part of the controller's I/O image table. The compact module design enables efficient expansion of digital input capacity in SLC 500 control systems.
- Material Handling Systems: Tracks package positioning on conveyors via proximity sensors
- HVAC Control Systems: Monitors safety switches, pressure sensors, and thermostat states
- Packaging Machinery: Interfaces with limit switches to confirm mechanical gate positions
- Assembly Lines: Verifies component presence using PNP photoelectric sensors
- Food & Beverage Processing: Operates valves, emergency stop buttons, and panel switches
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Module type: This is a 24V DC sinking input module, meaning input points require a positive 24V DC relative to the DC common.
DC Common: Connect the negative side of your 24V DC power supply to the DC Common terminal(s) of the module.
Field devices: Connect your dry contacts or sensor outputs (sourcing sensors) directly to input terminals numbered 0 through 15.
Wire size: Use up to 14 AWG wire secured under the self-lifting pressure plates of the removable terminal block.
Cable limit: Keep field wiring cable lengths under 15 meters (50 feet) per point for standard environments.
