PRODUCT INFORMATION
Product Overview
The General Electric IC695ALG508 is an RTD Input Module for the PACSystems RX3i platform. It provides eight isolated differential channels for direct temperature sensing or linear resistance inputs. Supported RTD sensor elements include Platinum, Nickel, Copper, and Nickel-Iron. Wiring configurations accommodate 2-wire, 3-wire, or 4-wire sensors. Internal temperature linearization is formulated according to ITS-90 standards.
This module mounts directly into an RX3i universal backplane. It supports Removal and Insertion Under Power during routine maintenance. Internal power draws 400 mA at 3.3 VDC and 200 mA at 5.1 VDC. Field wiring connects using compatible box-style or spring-style terminal blocks. Extended terminal block versions provide extra depth for shielded wiring. Diagnostic LEDs show module operational status and external field power presence.
