240 Series Input Modules
Simplifying large-scale cryogenic temperature measurement
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.

Overview
Integrates seamlessly with industry-leading Lake Shore Cernox®RTDs, platinum RTDs and DT 670 silicon diodes, providing the ideal solution for performing temperature measurements over a PLC network
Native support for PROFIBUS, allowing this module to be integrated into a wide range of PLC networks
Temperature values are communicated directly with the PLC master device, removing the need to use additional costly analogue conversion equipment or complex PLC programming to generate temperature values
Measurement circuitry based on Lake Shore’s industry leading benchtop instruments, allowing for longer cable runs between sensor and module; ideal for applications where sensors must be located in hazardous environments
Normal mode with EMF-cancellation and signal filtering for the best measurement possible or high-speed mode for the fastest notification of a temperature change
A high-quality OLED display on the front of the unit provides helpful status and measurement data; this is in addition to being able to access this information via the PLC network or the local USB connection
Convenient pluggable connectors allow individual sensors to be disconnected for maintenance without losing readings from other sensors on the same module
Easy DIN rail mounting with integrated rear connections allowing power and fieldbus communications to be shared between modules
