The Allen‑Bradley 1734‑IB2 delivers reliable digital DC sinking input for your control system. This compact POINT I/O module integrates two sink inputs rated at 24 Volts DC. Its maximum input current stays at 5 milliamps per channel. Engineers trust this module for its robust performance and efficient power dissipation of 2.4 BTU/hour. The module weighs only 30.9 grams and measures 56 x 12 x 75.5 millimeters. This lightweight design simplifies installation in tight cabinets.
Procurement & Buyer Guide for the Allen‑Bradley 1734‑IB2
Procurement managers value the 1734‑IB2 for its precise technical alignment with standard 24V DC sensor networks. The module uses a single‑key switch position on its base. It requires a POINTBus current of 75 milliamps at 5 Volts DC. This low power consumption reduces overall system load. The Removable Terminal Block (RTB) enables quick wiring changes without disturbing other components. Application engineers find the open‑style enclosure suitable for both horizontal and vertical mounting. The operating temperature range spans from -20 to 55 degrees Celsius. This tolerance ensures reliable operation in industrial environments. Network compatibility includes ControlNet, DeviceNet, EtherNet/IP, and other open networks. This flexibility simplifies integration into existing architectures.
Expert Technical Evaluation & Performance Review
The Allen‑Bradley 1734‑IB2 provides a sinking input design that matches most PLC digital input cards. Each input handles a maximum current of 5 milliamps. This low current protects connected sensors from overstress. The module dissipates a maximum of 0.7 Watts at 28.8V DC. Such thermal efficiency keeps nearby components cool. The input voltage range spans from 10 to 28.8 Volts DC. This wide range accommodates fluctuating power supplies. The 1734‑IB2 terminal base screw torque measures 0.8 N‑m. This specification ensures secure connections that resist vibration. The keyswitch must be in position 1 for proper operation. This mechanical interlock prevents incorrect insertion. The compact dimensions of 56 x 12 x 75.5 mm allow dense I/O grouping. Users can mount the module horizontally or vertically without airflow restrictions.
Logistics & Standard Packaging Details
All shipments include proper anti‑static packaging to protect the module during transit. The lightweight design reduces shipping costs while maintaining safety.
