Product Overview

The Allen-Bradley 1734-IE2I stands as a cornerstone for high-precision data acquisition within the POINT I/O family. This module provides two channels of isolated analog current inputs, specifically designed to interface with 4–20 mA or 0–20 mA transmitters. By offering channel-to-channel isolation, the 1734-IE2I eliminates ground loop interference, a common headache in distributed industrial environments. Its compact, modular form factor allows for seamless integration into DeviceNet, ControlNet, or EtherNet/IP networks through a POINT I/O adapter, making it an ideal choice for scalable process control and machine automation.

Technical Specifications

The 1734-IE2I delivers professional-grade accuracy through the following technical profile:

Engineering Advantages

• Total Channel Isolation: Unlike single-ended modules, the 1734-IE2I isolates each input channel from the backplane and from each other. This prevents noise cross-talk and protects your PLC processor from high-voltage transients on the field side.

• 16-Bit Precision Scaling: The high-resolution Delta-Sigma conversion allows for extremely granular monitoring of process variables. This is vital for applications like chemical dosing or pressure monitoring where minute changes signify critical process shifts.

• Harsh Environment Durability: Rated for an impressive temperature range of -40°C to +70°C, this module thrives in unconditioned control cabinets and outdoor remote I/O stations where standard commercial electronics fail.

• Bumpless Installation: The module snaps into a 1734-TB or 1734-TBS terminal base. Its "Removal and Insertion Under Power" (RIUP) capability allows technicians to replace modules without shutting down the entire I/O rack, significantly reducing system downtime.

FAQs

Q: Is this 1734-IE2I module 100% Brand New or refurbished?A: We sell 100% Brand New, original Allen-Bradley factory stock. Each module comes in its original sealed box with the manufacturer's warranty and a guaranteed authentic serial number.

Q: Can I use the 1734-IE2I to measure voltage signals like 0-10V?A: No. The 1734-IE2I is strictly for current signals (mA). For voltage inputs, you should look for the 1734-IE2V (non-isolated) or other voltage-specific modules within the POINT I/O range.

Q: Does this module require a separate power supply for the loop?A: The module itself runs on POINT I/O bus power, but for 2-wire transmitters, you typically provide field power (24V DC) through the terminal base. 4-wire transmitters will use their own external power source while feeding the current signal into the IE2I.

Q: What is the correct Keyswitch Position for this module?A: You must set the 1734 terminal base keyswitch to Position 3 before inserting the 1734-IE2I. This mechanical interlock prevents the insertion of the wrong module type into a pre-wired base.
