The 240 Series is a cryogenic temperature sensor input module designed for integration with Lake Shore Cernox® RTDs, platinum RTDs, and silicon diodes in PLC-based control systems. It supports PROFIBUS-DP, Modbus RTU, and ASCII serial communication, enabling direct temperature value transmission without PLC-side conversion. The module features an onboard OLED display for real-time status and measurement data, easy DIN rail mounting, and pluggable terminal blocks for maintenance without disrupting other sensors. It accommodates sensor cable runs up to 300 m and offers normal mode with thermal EMF cancellation or high-speed mode (240-2P only) with configurable update rates from 1 ms. Measurement circuitry derives from Lake Shore benchtop instruments and supports native calibration files for accurate temperature conversion. Configuration is performed via USB using MeasureLINK™ software.
The new 240 Series offers a convenient, modular input solution for precision monitoring of cryogenic temperature sensors in large-scale applications employing distributed PLC-based control.
Lake Shore benchtop cryogenic instruments are trusted throughout the world for precision temperature measurement—now that same measurement performance can be achieved in widely distributed high energy applications like particle accelerators and fusion reactors as well as other large industrial sites.
