The Limit control L91 is an over temperature or a high limit safety device with a latching output that could remove the power while the process is in abnormal condition, for example the process higher than high limit set point or lower than the low limit set point.
The high temperature limit controller takes an input from the universal input which is fully programmable for PT100, thermocouple types J, K, T, E, B, R, S, N, L, C, P and 0~60mV. The controller equipped with 2 Amp form C relay as limit control output and equipped with the optional RS-232 or RS-485 communication, retransmission output and transmitter power supply.
As a professional and experienced manufacturer, we supply high-performance and quality temperature controllers, which are also called temperature control, electronic temperature control, electronic temperature controller, and PID controller.
