NTC thermostat W09C

relaywall-mountedwith temperature probe

Controller for refrigerating units, 3 inputs, 3 outputs and Real Time Clock This controller can perform real-time defrost cycles thanks to the Real Time Clock function. The 3 inputs for PTC or NTC temperature probes can be used to adjust the cell temperature, to measure the evaporator temperature and to measure an auxiliary temperature (eg product temperature). The 3 outputs can be used to control the compressor, the defroster, the evaporator fans or, as an alternative to any of the previous functions, an auxiliary or alarm device. It can also be equipped with an internal buzzer for the acoustic signaling of alarms. As an alternative to the evaporator probe or the auxiliary probe, it is possible to have a digital input that can be programmed to perform various functions such as cell door signal, defrost commands, the selection of a different temperature control, the signaling of a external alarm, the activation of a continuous cycle, the activation of the auxiliary output etc. FUNCTION - Controller for refrigeration units, Controller DIMENSIONS - 75 x 122 mm DISPLAY - 1 display with 3 digit POWER SUPPLY - 100… 240 Vac INPUTS - 1 digital, NTC, PTC-NTC NUMBER OF OUTPUTS - 1, 2, 3 OUTPUTS - Relay DIGITAL INPUTS - 1 INTERFACE - RS 485 with external module A30, TTL Modbus SPECIAL FUNCTIONS - Acoustic alarm (buzzer), Duty cycle function, Energy saving, Real time clock, Remote display (TVR) CONTROL - ON/OFF EXTRACTABILITY - Not extractable, With fix terminal block DEFROST CONTROL - At intervals with electric heating or hot gas / reverse cycle, At intervals with for compressor stop, electric heating or hot gas/reverse cycle, With Real Time Clock for compressor stop
