Product Details
Module Overview
The 1734-OE2V is a high-precision analog output module designed for the Allen-Bradley POINT I/O platform. This module provides two single-ended, non-isolated voltage outputs, typically used to drive Variable Frequency Drives (VFDs), pressure regulators, or proportional valves that require a standard 0–10V DC control signal. With its 14-bit resolution and rapid conversion rate, the 1734-OE2V delivers smooth, granular control for process loops where high-speed response and signal accuracy are critical. Its ultra-compact 12mm width makes it an ideal choice for distributed I/O racks with limited space.

Signal Integrity and Wiring
Because the 1734-OE2V features non-isolated, single-ended outputs, both channels share a common return path. To maintain the 14-bit signal integrity and prevent electrical noise from affecting the output, it is essential to use shielded twisted-pair cabling (such as Belden 8761). The shield should be grounded at only one end, typically at the POINT I/O chassis ground, to avoid ground loops that could introduce offsets into the 0–10V signal.
Installation and Hardware Requirements
The 1734-OE2V is a "plug-in" module that must be seated into a 1734-MB mounting base. It requires a Removable Terminal Block (RTB), specifically the 1734-RTB (screw) or 1734-RTBS (spring), to interface with field wiring. Before installation, the mechanical keying on the mounting base must be set to Position 4 to ensure the module is correctly aligned and protected from mismatched voltage levels in the rack.
Technical FAQ
Can the 1734-OE2V be used for -10V to +10V bipolar signals?
No. This specific module is designed for unipolar 0–10V DC operation. For bipolar voltage applications, the 1734-OE2C or a specialized bipolar module would be required.
How do I handle the "Signed Integer" data format in my logic?
In Studio 5000, the 0–10V output is typically represented by a value range of 0 to 10,000 (or 0 to 16,383 depending on scaling). Using "Signed Integer" allows the controller to handle the data with standard math instructions before sending the final value to the module's output register.
What happens if the 24V DC field power is lost?
The module requires 24V DC field-side power (provided via the power bus in the mounting base) to generate the 0–10V signal. If field power is lost, the "NODE" or "POINT" status LED will typically flash red, and the outputs will drop to 0V.

Navigating Industrial Automation Failures: Types, Causes, and Mitigation Strategies
Modern manufacturing relies heavily on automated control systems to maximize throughput and maintain product quality. However, unplanned downtime in industrial automation can cost facility operators thousands of dollars per hour. Understanding how programmable logic controllers (PLCs), distributed control systems (DCS), and field instrumentation fail empowers engineering teams to implement robust preventive maintenance strategies.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
The Role of Intrinsic Safety Barriers in PLC and DCS Architectures
Implementing robust protection in hazardous industrial environments represents a fundamental safety requirement in factory automation. Process facilities often handle volatile gases, dusts, and chemical agents that pose significant combustion risks. Consequently, control system engineers must deploy energy-limiting interfaces to isolate safe-area control cabinets from hazardous-area field instrumentation. This article examines the function, selection, and electrical principles of intrinsic safety barriers within modern PLC and DCS networks.
