Allen Bradley 1734-OE2V Analog Output Module

The Allen Bradley 1734-OE2V, part of the Bulletin 1734 Point I/O series, operates as a compact, high-density analog voltage output module designed for distributed control applications. It provides two single-ended output channels capable of driving field actuators, control valves, and variable frequency drives (VFDs) with high precision over standard voltage control loops.

Hardware Specifications

Distributed Signal Processing & Point I/O Architecture

The 1734-OE2V converts 14-bit signed digital values from the host controller into proportional analog voltage signals. Designed to snap directly onto a 1734 wiring base (such as the 1734-TB or 1734-TBS), the module communicates with the primary programmable automation controller (PAC) via a Point I/O bus interface adapter (e.g., 1734-AENT or 1734-PDN). Key features include:

• Configurable Output Ranges: Software-selectable range configuration per channel (0 to 10 VDC or bipolar -10 to +10 VDC) without physical jumper changes.

• Onboard Diagnostics: LED indicators provide immediate status for module health, bus communication, and channel activity.

• Hot-Swappable Architecture: Supports Removal and Insertion Under Power (RIUP), enabling module replacement without interrupting adjacent Point I/O modules on the DIN rail.

Frequently Asked Questions

Q: Can channels on the 1734-OE2V be individually configured for different voltage ranges?

A: Yes, each of the 2 single-ended channels can be independently configured in Studio 5000 / RSLogix 5000 software to operate in either 0 to 10 VDC or -10 to +10 VDC mode.

Q: What wiring bases are compatible with the 1734-OE2V module?

A: The module is compatible with standard Bulletin 1734 terminal bases, including the 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS bases.

Field Installation Guidelines

• Mount the 1734 terminal base securely onto a grounded 35 mm DIN rail before snapping the 1734-OE2V module into place.

• Set the mechanical keying switch on the terminal base to the designated position for voltage output modules to prevent accidental insertion of incorrect module types.

• Route analog signal wiring using shielded, twisted-pair cable to minimize electrical noise interference on 0-10V loop signals.

• Ensure proper grounding by landing the cable shield at a single end (typically at the panel ground bar) rather than floating or grounding at both ends.
