Features:
- Sixteen digital sourcing inputs support efficient monitoring of industrial switches and field sensing devices.
- Fast 8 ms ON/OFF signal response improves input processing reliability in machine automation applications.
- Low backplane current consumption reduces overall system power demand while maintaining stable operation.
Allen-Bradley 1746-IV16 is a digital DC input module used in SLC programmable controller systems for industrial signal acquisition and machine monitoring tasks. The module supports 16 sourcing input channels for connection to field sensors, switches, and control devices operating with 24V DC signals. Compact integration within the SLC chassis architecture allows efficient use of cabinet space while simplifying control system expansion. The module also supports reliable field signal monitoring in manufacturing and process automation applications.
The module operates with input voltages ranging from 10 to 30V DC and provides stable signal processing with 8 ms maximum ON and OFF response times. Allen-Bradley 1746-IV16 requires minimal backplane current while maintaining dependable digital input performance across all channels. Installation procedures are straightforward through chassis card guides and locking tabs that secure the module during operation. Unused chassis slots can also be protected using slot filler accessories to reduce debris accumulation inside the enclosure.
Allen-Bradley 1746-IV16 is commonly applied in packaging systems, material handling equipment, production machinery, and industrial process control systems requiring reliable discrete input monitoring. Compatibility with SLC communication modules, analog I/O cards, and EtherNet/IP adapters allows gradual modernization of installed automation systems. Continued support from Rockwell Automation further extends operational service life for legacy SLC platforms. Flexible integration capability makes the module suitable for both existing installations and replacement maintenance projects.
The 1746-IV16 Allen-Bradley SLC 16 Point Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
