NTC thermostat W09Y

relaywall-mounteddigital

Controller for refrigerating units, 3 inputs and 3 outputs 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 set, 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, 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 CERTIFICATIONS - CE
