Allen-Bradley 1734-OX2 POINT I/O Digital Relay Output Module

The Allen-Bradley 1734-OX2, also cataloged as the 1734-OX2 Digital Output Module, operates as a dedicated hardware component for relay contact signal execution within POINT I/O platforms.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

• The Allen-Bradley 1734-OX2 interfaces directly with the POINTBus backplane, maintaining backplane bus communication velocity across EtherNet/IP deterministic networks.
• Dual Form C isolated mechanical relay outputs allow independent switching of AC and DC field loads without cross-channel electrical interference.
• Firmware flash compatibility across primary controller racks guarantees synchronized output state updates and continuous diagnostic feedback during operation.

Frequently Asked Questions

Q: Does the 1734-OX2 module support hot-swapping or Removal and Insertion Under Power (RIUP)?

A: Yes, the module supports RIUP when installed on a compatible 1734 terminal base assembly, provided the field power load currents are safely isolated prior to removal.

Q: How does the 1734-OX2 handle channel isolation between its output points?

A: The Form C relay contact outputs provide galvanic channel-to-channel isolation, allowing each point to switch distinct potential sources up to rated field limits.

Field Installation Guidelines

Mount the terminal base assembly securely onto a grounded 35 mm DIN rail before inserting the 1734-OX2 module. Connect field wiring to the removable terminal block using proper wire strip lengths and torque specifications. Route AC and DC field output cables in separate channels away from low-voltage communication lines to minimize electromagnetic interference. Ensure that external inductive loads connected to the Form C relay contacts utilize arc suppression devices to prevent contact welding and extend relay operating lifespan.
