Allen-Bradley 1734-IE2C Analog Input Module - Two 4-20 mA Channels

Product Overview

The 1734-IE2C is a current input analog module from Allen-Bradley. It belongs to the POINT I/O family. This module has two single-ended, non-isolated channels. Each channel accepts 0-20 mA or 4-20 mA signals. It offers 16-bit resolution across 0 to 21 mA. The module uses Delta-Sigma conversion. It stores data in signed integer format. Absolute accuracy is 0.1% Full Scale at 25 °C. The module draws 75 mA at 5V DC. It dissipates 0.6 W at 28.8V DC. The compact size is 56 x 12 x 75.5 mm. It weighs just 0.036 kg. You can mount it horizontally or vertically on a 35 mm DIN rail.

Application Scenarios

This module suits many industrial applications. It works with any POINT I/O communication adapter. Use it with ControlNet, DeviceNet, or EtherNet/IP networks. It fits Allen-Bradley controllers like ControlLogix and CompactLogix. Typical uses include process monitoring and control. It reads current signals from sensors and transmitters. The module handles 4-20 mA loops in factory automation. It also works in building management systems. The high resolution ensures precise measurements.

Installation & Maintenance Guide

Install the module on a terminal base first. Choose 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS. Set the keyswitch to position 3. Then snap the module onto the base. Mount the assembly on a 35 mm DIN rail. You can mount it vertically or horizontally. Use shielded twisted-pair wires for signals. Strip wires to the correct length. Connect them to the appropriate terminals. Apply power between 10 and 28.8V DC. The module requires no calibration. It comes factory calibrated. For maintenance, check connections regularly. Keep the area clean. Replace the module if it fails.
