1734-IB4D Allen-Bradley POINT I/O Digital Sinking Input Module with Diagnostics
1734-IB4D is a 4-channel digital DC sinking input module from the Allen-Bradley POINT I/O 1734 series. It is built for compact distributed control systems. Each input has a status LED. Diagnostics help engineers find faults fast. The module supports ControlNet, DeviceNet, EtherNet/IP, and other open networks. It fits 1 keyswitch position. Installation is simple on the POINT I/O mounting base.
The module works with 24V DC nominal input. Input current is 5 mA maximum. POINTBus current is 50 mA. Power dissipation is 1.9 BTU/hour. Maximum thermal dissipation at 28.8V DC is 3.4 BTU/hour. The compact housing measures 2.2 x 0.47 x 2.97 inches. It weighs about 1.14 ounces. The open-style enclosure mounts horizontally or vertically.

Note: The 1734-IB4D is a digital input module. It does not provide analog measurement ranges, frequency response, sensitivity, linearity, or resolution. Key electrical limits are 10 to 28.8V DC input and 5 mA maximum input current. Environmental tolerance is -20 to 55°C. The open-style housing suits controlled industrial cabinets. Diagnostics and status LEDs support fast fault finding. Use shielded wiring and good grounding to reduce electrical noise in industrial panels.
Installation Guide
- Mount the POINT I/O base horizontally or vertically.
- Set the keyswitch to position 1.
- Insert the 1734-IB4D module into the base.
- Wire inputs 0 to 3 to the Removable Terminal Block.
- Tighten terminal screws to 0.8 N-m (7 lb-in).
- Check input voltage stays within 10 to 28.8V DC.
- Connect the network adapter for ControlNet, DeviceNet, or EtherNet/IP.
Commissioning and Maintenance
- Use the status LEDs to confirm each channel.
- Verify diagnostics in the connected controller or software.
- Keep the enclosure free of dust and moisture.
- Check terminal torque during routine service.
- Replace the module only after confirming base and wiring are healthy.
Compatibility
The 1734-IB4D fits the Allen-Bradley POINT I/O 1734 system. It works with ControlNet, DeviceNet, EtherNet/IP, and other open networks. It uses a Removable Terminal Block on the mounting base. Confirm adapter and power budget before installation.
