The TR-101 digital temperature relay is designed to measure and control the temperature of the device using four independent sensors connected in a two- or three-wire circuit, followed by displaying the temperature on the display.

The device can be used in various industries, utilities and agriculture.

The device allows you to perform the following functions:

• temperature measurement through four independent channels using standard sensors
• temperature regulation according to the proportional-integral-differential (PID) law, with the original key element (relay)
• two-position temperature regulation
• display the current measured temperature value on the built-in LED digital indicator
• transmitting to the computer the value of the measured temperatures of the monitored sensors using the standard Modbus RTU protocol
• determination of a break or a short circuit in the lines of connected sensors
• digital filtering and correction of the measured temperature
• programming with buttons on the front panel and through the PC
• saving settings when power is turned off
• protection of settings from unauthorized changes

The TR-101 has universal power and can use any voltage from 24 to 260V, regardless of polarity.
