Allen-Bradley 1734-OE2V POINT I/O 2-Channel Analog Voltage Output Module

Configured for high-density analog voltage signal generation in Allen-Bradley ControlLogix and CompactLogix platforms, the Allen-Bradley 1734-OE2V (1734-OE2V POINT I/O 2-Channel Analog Voltage Output Module) provides direct physical/electrical execution. The module converts 14-bit digital value registers from the controller backplane into 2 single-ended 0 to 10 VDC analog control signals for driving field actuators and speed reference inputs.

Suffix Breakdown & Model Matrix

The catalog number 1734-OE2V follows standard Allen-Bradley POINT I/O module naming conventions:

• 1734: Identifies the compact modular POINT I/O hardware system family.

Hardware Specifications

Industrial Control & Backplane Communication Properties

As a core analog processing unit within Allen-Bradley distributed control structures, the 1734-OE2V features low-latency bus interaction and precise output signal scaling:

• Backplane Bus Communication Velocity: High-speed POINTBus backplane connections transfer 14-bit digital output data frames continuously from the network adapter module with sub-millisecond updates across deterministic EtherNet/IP networks.
• I/O Density Scaling: Packs 2 high-resolution voltage output channels into an ultra-slim 12 mm module width, maximizing rack space efficiency while maintaining hardware-level D/A conversion precision.
• Firmware Flash Compatibility: Supports seamless hardware execution across dynamic controller firmware flashing events, preserving output scaling configurations and fault-state hold settings stored in non-volatile memory.

Frequently Asked Questions

Q: Are the analog output channels on the 1734-OE2V isolated from each other?

A: No, the 1734-OE2V features single-ended non-isolated output channels that share a common negative reference return line.

Q: What mounting base hardware is required to install the module on a standard DIN rail?

A: The module snaps directly into a standard 1734-TB or 1734-TBS POINT I/O terminal base assembly mounted on a 35 mm DIN rail.

Field Installation Guidelines

Strict adherence to proper mechanical assembly and wiring practices ensures stable D/A conversion accuracy in noisy electrical environments:

• Mechanical Mounting and Terminal Base Assembly: Snap the 1734 terminal base securely onto the 35 mm DIN rail before inserting the 1734-OE2V module. Ensure the mechanical keying dial on the base is rotated to the correct position for analog output modules prior to seating.
• Wiring and Signal Shielding: Connect analog voltage output devices using two-conductor twisted-pair shielded cable. Connect the cable shield to the cabinet single-point ground bus bar; do not ground shields at the field device to prevent ground loop noise from shifting signal accuracy.
• Cable Separation: Route low-voltage 0 to 10 VDC analog output lines in dedicated wireways separate from 120/240 VAC power lines and variable frequency drive motor cables to prevent electromagnetic noise induction.
