GE IC695ALG600 RTD I/O Modules
Programmable Controllers
RTD I/O Modules
The RTD Input Modules provide RTD inputs that allow the direct connection of 2 and
3-wire RTD temperature sensors without using external signal processing (transducers,
transmitters, etc.). All analog and digital processing of the RTD signal is performed on
the module.
IC695ALG600 RTD IC695ALG508 RTD HE693RTD600
Product Name
Universal Analog and configurable for
Current, Voltage, RTD, Thermocouple and
Resistive. High Density (8 Channel) Requires
Cold Junction Compensation; are available
for Thermocouple configurations
(IC695ACC600 contains 2 CJCs)
Isolated RTD Input module (also
supports Resistive) provides eight isolated
differential Resistive or RTD input channels.
Each channel can be individually configured
for 2, 3, 4 wire RTD or Resistance.
