Allen-Bradley 1746-IV16 Module

The Allen-Bradley 1746-IV16 is a 16-channel sourcing digital DC input module tailored for SLC 500 PLC systems, delivering reliable discrete signal acquisition from industrial sensors, switches, and binary devices in manufacturing, material handling, and process control environments requiring robust, space-efficient I/O expansion. It excels in applications needing consistent detection of on/off states for automation and monitoring tasks.

1. 16 Sourcing DC Input Channels: Dedicated sourcing configuration supplies voltage to field devices, ideal for sensors/switches without internal power, streamlining wiring and reducing external component needs.
2. 10–30 VDC Voltage Flexibility: Nominal 24V DC operation with a wide range to match standard industrial sensors/actuators, eliminating extra power supplies or convertersRockwell Automation.
3. Robust Electrical Isolation: Communication circuits isolated to 500V DC; backplane isolated to 1500V AC to prevent ground loops, voltage spikes, and cross-talk for signal integrityRockwell Automation.
4. 8 ms Standard Response Time: Consistent on/off transition delay balances noise immunity and real-time control, suitable for general industrial discrete monitoring.
5. Per-Channel LED Indicators: Instant visual confirmation of input status for quick troubleshooting and maintenance, minimizing downtime from wiring or device faults.

Application Areas:

1. Conveyor and material handling system control
2. Packaging and labeling machinery operation
3. Assembly line discrete device control (sensors, actuators)
4. Industrial pump and valve on/off control
5. Automated storage and retrieval systems (AS/RS)
6. Machine tool auxiliary function control
