IC670ALG621 GE Fanuc Analog RTD Input Module

IC670ALG621 GE Fanuc Analog RTD Input Field Control Module

Product Introduction

The IC670ALG621 is an analog RTD input module from GE Fanuc. It belongs to the Field Control series. This unit receives up to four independent RTD signals. Then it processes them in the field using advanced electronics. After that, it sends a digital signal to the Bus Interface Unit. The BIU connects to a GE Fanuc Genius network of controllers.

Measuring temperature is vital in many industrial processes. The most common method uses Resistance Temperature Detectors, or RTDs. The IC670ALG621 handles this task as a solid-state intelligent module. It reads RTD signals at different levels. Moreover, it interprets those readings based on pre-configured reference parameters.

Technical Specifications

The IC670ALG621 provides four RTD input channels. The input resistance range spans 0 to 3276.7 ohms. Operating frequency is 50 to 60 Hz. This module is PT-100 compatible. It also supports other RTD types. These include 10-Ohm Platinum (PT), 25-Ohm Platinum (IPTS-68), and 25.5-Ohm Platinum with alpha = 0.00392 at 0 °C Lab Std.

Furthermore, both 3-wire and 4-wire configurations work with this module. Users configure all settings from the BIU. A handheld configuration tool handles this task, and it is sold separately. Adjustable parameters include the number of active RTD inputs, the byte length of output data, and the line frequency. The IP rating is IP 20.

Mechanical and Environmental Parameters

The operating temperature range is 0 °C to 55 °C. Operating humidity ranges from 5% to 95%, non-condensing. The module requires protection from dust and direct water contact. Therefore, follow the manufacturer's installation recommendations carefully. The IP 20 rating means the unit resists solid objects larger than 12.5 mm. However, it does not protect against water.

Installation Guide

First, mount the IC670ALG621 in a suitable Field Control terminal base. Next, connect the RTD sensors. Use 3-wire or 4-wire wiring as needed. Then, attach the Bus Interface Unit. After that, link the handheld configuration tool to the BIU. Finally, set the active channels and line frequency.

Besides, verify the input resistance stays within 0 to 3276.7 ohms. Check that the environment meets the humidity and temperature limits. Keep the module away from dust and moisture. Since the IP rating is only IP 20, install it inside a protective enclosure. Confirm all wiring before applying power.
