GE HE693RTD601 RTD I/O Modules
PACSystems RX3i Programmable Controllers
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.

Programmable Controllers
The Millivolt Input Modules allow Millivolt level signals, such as bridged strain gages
(load cells) to be directly connected to the PLC without external signal processing
(transducers, transmitters, etc.) All analog and digital processing of the signal is
performed on the module.
