Allen-Bradley 1734-OE4C 4-Channel Analog Current Output Module – POINT I/O Series
Imagine a continuous process line — a chemical dosing system, a precision tension control loop, or a variable-speed drive network — suddenly losing its analog command signal. Actuators freeze at their last position, drives coast uncontrolled, and the entire production cell enters an unsafe state. Every second of unplanned downtime translates directly into scrap, safety risk, and revenue loss. The Allen-Bradley 1734-OE4C exists precisely to prevent that scenario: a purpose-built, field-proven analog current output module that delivers four independent, isolated 4–20 mA channels with the reliability that mission-critical industrial processes demand.
Within Rockwell Automation’s POINT I/O platform, the 1734-OE4C occupies the high-density analog output tier — offering four current-output channels in a single slim POINT I/O slot, making it the preferred choice for engineers who need to maximize channel density without sacrificing signal integrity. Globally, the POINT I/O family is deployed across tens of thousands of machine-level and distributed control applications in automotive, food & beverage, oil & gas, and water treatment industries, and the 1734-OE4C is one of its most specified analog modules.

Key Features & Benefits
- 4 Independent Current Output Channels — Drive four separate field devices (control valves, VFDs, positioners) from a single module slot, maximizing panel density.
- 4–20 mA Industry-Standard Signal — Compatible with virtually all analog field instruments; inherently noise-immune over long cable runs.
- 13-Bit Resolution — Fine-grained control resolution supports tight process loops where coarse stepping is unacceptable.
- Channel-to-Backplane Isolation — Protects the controller backplane from field-side transients and ground loops.
- Hot-Swap Capable — POINT I/O architecture supports module replacement under power (with appropriate adapter configuration), minimizing maintenance downtime.
- Compact POINT I/O Form Factor — Slim profile enables high-density I/O assemblies in space-constrained enclosures.
- Studio 5000 / RSLogix 5000 Integration — Native Add-On Profile (AOP) support for rapid configuration and diagnostics within the Rockwell software ecosystem.
- Diagnostic Feedback — Module-level and channel-level diagnostics surfaced through the controller for proactive fault detection.
Industry & Equipment Applications
- Oil & Gas: Control valve positioners on wellhead and pipeline skids; flow control loops in separation trains.
- Chemical & Petrochemical: Dosing pump speed references; reactor temperature setpoint transmission.

Frequently Asked Questions
Q1: Is the 1734-OE4C compatible with EtherNet/IP networks?
A: Yes. When paired with a 1734-AENT or 1734-AENTR adapter, the module communicates over EtherNet/IP and is fully configurable in Studio 5000 Logix Designer.
Q2: Does the 1734-OE4C support HART protocol?
A: No. The 1734-OE4C is a standard 4–20 mA current output module and does not support HART pass-through. For HART-enabled analog output, consider the 1734-OE4CH.
Q3: Is a wiring base (terminal base) included with the module?
A: No. The terminal base (e.g., 1734-TB) must be ordered separately. Please specify when submitting your inquiry so we can quote the complete assembly.
Q4: Can Konmask.com supply both new and refurbished units?
A: Yes. We can supply factory-new, surplus-new (unused), and professionally refurbished units depending on availability and your budget requirements. Condition is clearly stated in all quotations.
Q5: What is the typical lead time for the 1734-OE4C?
A: Lead time varies by stock availability. In-stock units typically ship within 3–5 business days. For out-of-stock items, lead time is quoted individually. Contact us for current availability.
Q6: Do you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, and certificate of origin. Additional documentation (e.g., Form E for ASEAN, EUR.1 for EU) can be arranged upon request.
