Description

Allen-Bradley 1734-0E2C 2-Channel Analog Output Module

Product Dimensions：

The Allen-Bradley 1734-OE2C is a high-performance analog output module from the POINT I/O™ family. It is designed to provide precise current signals to field devices such as actuators, valves, and motor controllers in a modular, space-saving format.

Product Detailed Description

The 1734-OE2C is a 2-channel analog current output module. It converts digital values from the PLC controller into proportional analog signals (typically 4–20 mA or 0–20 mA). As part of the POINT I/O system, it is known for its “slice” architecture, allowing users to add I/O point-by-point to minimize costs and cabinet space. It connects to the controller via a POINT I/O communication adapter (such as Ethernet/IP, ControlNet, or DeviceNet).

Technical Parameters

Product Advantages

• Modular Scalability: The “slice” design allows you to add exactly two channels at a time, preventing “over-buying” of I/O points.
• High Precision: With 13-bit resolution and high accuracy, it is suitable for demanding process control applications where fine adjustments are required.
• Hot-Swappable (RIUP): Supports Removal and Insertion Under Power, allowing you to replace a faulty module without shutting down the entire system, significantly reducing downtime.
• Diagnostic LEDs: Features clear status indicators (Module Status, Network Status, and individual Channel Status) for rapid local troubleshooting.
• Compact Footprint: Ideal for decentralized I/O stations where space is at a premium.

Important Considerations (Precautions)

• Calibration: While factory-calibrated, periodic software-based calibration is recommended to maintain peak accuracy over the life of the module.
• External Power Supply: This module requires an external 24 V DC power source via the power bus. Ensure your power supply is appropriately sized for the total number of analog modules in the rack.
• Shielding: To prevent electromagnetic interference (EMI), use shielded twisted-pair cables for signal runs and ensure the shield is grounded at only one end.
• Open-Circuit Detection: The module can detect if the output loop is broken; ensure your PLC code is programmed to monitor these diagnostic bits for system safety.

Product Applications

The 1734-OE2C is widely used in diverse industrial environments:

• Process Control: Regulating the position of pneumatic or electric control valves in chemical or water treatment plants.
• Motor Speed Control: Providing a speed reference signal (4–20 mA) to Variable Frequency Drives (VFDs).
• Heating Control: Interfacing with SCR power controllers to manage industrial furnace temperatures.
• Actuator Management: Driving proportional actuators in HVAC systems or specialized assembly machinery.
• Data Transmission: Retransmitting process variables to remote chart recorders or secondary monitoring displays.
