Native fieldbus integration
The 240 Series modules connect with PROFIBUS‑DP compatible networks, giving PLCs direct access to temperature values. This eliminates the need for additional I/O modules and complex conversion algorithms within the PLC to generate values when working with cryogenic temperature sensors.
The ability to communicate temperature directly with a PLC has many advantages:
- Commercially supported solution with proven results
- No additional I/O modules required to energize or read the temperature sensor
- The process of converting from measured voltage or resistance to temperature units does not need to be programmed into the PLC’s control logic.
Internally converting to temperature units represents the greatest reduction in time, cost, and risk when building a control system that includes cryogenic temperature management. Creating code that generates temperature values reliably can take days and the ability to maintain that code then becomes a liability if the attached sensor ever needs to be changed. Lake Shore 240 Series modules are the only low-risk option available for cryogenic temperature control in a PLC network. Direct instrument connection via USB makes configuration and maintenance easy and can be used for permanent temperature monitoring in systems not compatible with PROFIBUS-DP.
