Allen-Bradley 1734-IE4C 4-Channel Analog Input Module

Product Overview

The Allen-Bradley 1734-IE4C is a 4-channel analog input module. It belongs to the POINT I/O family. This module accepts current signals from 4-20 mA or 0-20 mA. It uses Delta-Sigma conversion for high accuracy. The data format is signed integer with 16-bit resolution. Each channel is single-ended and non-isolated. The module has a key switch position of 3. It dissipates 0.55 W at 28.8V DC. The thermal dissipation is 2.0 BTU/hr. Compatible terminal bases include 1734-TB3, 1734-TB3S, 1734-TOP, 1734-TOPS, 1734-TB, and 1734-TBS. The enclosure type rating is open.

Application Scenarios

This module is used in industrial automation. It interfaces with process variables like pressure, temperature, and flow. These signals come from 4-20 mA transmitters. The 1734-IE4C works with CompactLogix and ControlLogix controllers. It supports rack-optimized connections. The module also works with any POINT I/O communication adapter. It is ideal for high-density analog input applications.

Installation & Maintenance Guide

Mount the module on a DIN rail. Use zinc-plated yellow-chromate steel rails for grounding. Secure the rail every 200 mm. Use end anchors correctly. Install or remove the module only when backplane power is off. This prevents electrical arcs. The module can be installed before or after the base is secured. Ensure proper grounding via the DIN rail to chassis ground.
