DIN rail mountable Temperature Controllers
Available from Eurotherm
Designed to offer outstanding control performance in a compact DIN rail package the RFS provides a comprehensive solution for a wide variety of applications: such as plastic manufacturing, packaging machinery and food processing applications requiring precise heat/cool control and process protection alarming.
Ideal as a slave PID loop to a programmable logic controller the RFS offers a cost effective alternative to performing loops in a PLC while at the same time improving loop performance. All inputs and outputs can be read directly over the Modbus communication interface by the supervisory host system. Additionally, the master can write to RFS outputs that are not assigned as alarm or status functions. This expands the available PLC and host supervisory system I/O, simplifies machine troubleshooting and provides the ability to perform remote diagnostics.
The RFS accepts one universal process input suitable for thermocouple, resistance thermometer or linear mV/mA and coupled with a responsive Smart PID self tuning algorithm it is equipped with special functions including soft start and non-linear cooling. Smart tuning automatically adjusts the PID sets according to the current process dynamics without the need to cycle the process and therefore has no detrimental effect on the current operating conditions.
