GE Horner HE693RTD600T Serie 90-30 Widerstandstemperatur-Eingangsmodul

Description

The HE693RTD600T is a high-precision resistance temperature device (RTD) input module developed by GE Horner for the Series 90-30 programmable logic controller platform. This module allows direct connection of RTD temperature sensors to the PLC without requiring external transmitters, transducers, or signal conditioning hardware. It performs all analog and digital processing directly on the module, writing formatted temperature readings in 0.5 degC or 0.5 degF increments directly to the controller %AI input table. Equipped with six independent channels, the device ensures reliable and localized temperature tracking across diverse industrial environments.

Features

• Six individual channels supporting multi-point temperature sensor integration
• Onboard 16-bit integrating analog-to-digital converter for high-resolution signal processing
• Built-in fault protection utilizing a Zener diode clamp to safeguard internal circuitry
• High input impedance to preserve signal integrity over long field wiring runs
• Direct reporting of temperature values to the controller memory map without external signal conversion

Applications

• Real-time temperature monitoring in process control industries
• Machinery thermal protection systems
• Multi-channel HVAC and environmental control networks
• Power generation and distributed system thermal logging

Technical Specifications

Installation Guidelines

• Install the module directly into a compatible slot of the Series 90-30 PLC rack, ensuring it is fully seated.
• Connect field sensors using shielded, twisted-pair extension wiring to provide maximum electrical noise immunity.
• Ground the wiring shields at a single point only; if grounding at the module end, utilize the designated shield ground terminal points.
• Route RTD signal cables away from high-voltage lines, motor conduits, and other significant sources of electromagnetic interference.
