Product Summary
The Allen-Bradley 1734‑IE2V is a POINT I/O analog input module that delivers two high‑accuracy voltage channels. It converts critical process variables like flow and pressure into 16‑bit signed integer data. This compact module is the practical choice for remote I/O applications.
Product Procurement & Buyer Guide
This module solves the common pain point of sparse I/O points in remote locations. The 1734-IE2V provides two single‑ended voltage inputs in a low‑cost form factor. It supports unipolar and bipolar signals from 0‑10V or ±10V.
The unit uses a Delta Sigma converter for reliable accuracy. This converter maintains 0.1% Full Scale at 77 °F. Engineers gain confidence in monitoring temperature or vibration signals.
This module is compatible with any POINT I/O adapter. Its compact design mounts easily on a DIN rail. You can integrate it directly into existing Rockwell Automation architectures without extra wiring complexity.
The module dissipates only 0.75 Watts at 28.8 Volts DC. This low power budget helps you manage thermal loads in crowded enclosures. It features six bytes of data for channel data and status.
You can set configurable latching alarms for your process. This system supports Low, Low Low, High, and High High levels. You can adjust the input rate to match varying conditions like slow or fluctuating flows.
This practical solution handles small to medium I/O counts effectively. It reduces overall system cost by placing intelligence near the sensors. The 1734-IE2V is the right choice for distributed control.
Step-by-Step User & Installation Guide
Mounting the Module
Attach the 1734‑IE2V module to a standard DIN rail. Align the module’s slot with the rail until it clicks. Ensure the key switch is set to position 3 for correct installation.
Wiring the Inputs
Connect your analog voltage source to the terminal block. Use a shielded cable for long runs to reduce noise. Wire the positive signal to the channel input and the common to ground.
Understanding the Status Indicators
The front panel provides clear diagnostic feedback. A steady green light shows the module operates properly. A flashing green means it needs commissioning after an incomplete configuration.
A solid red light signals an irrecoverable fault. A flashing red indicates a recoverable fault you can clear. Alternating red and green means the module runs a diagnostics test.
Use these indicators for a quick system check. You can confirm power status and signal quality instantly. This visibility reduces downtime during commissioning and normal operation.
Configuring the Signal Range
This module accepts two user‑configurable voltage ranges. Select 0...10V with a -0.0V under and +0.5V over range. Choose ±10V with a -0.5V under and +0.5V over range for bipolar signals.
Data Format and Resolution
The converter outputs a signed 16‑bit integer ranging from -32,768 to +32,767. It uses a 15‑bit signed resolution for precise measurements. This data format integrates directly with your control logic.
