TRW230-200.34 Wpps-20A K1=30A LON

The installation unit TRW230-100.14 for refrigerating chambers and cooling cells unites control and power section in a complex and at the same time optically fastidious way. That way, the cooling regulation contains all functions and components, in order to control compressors with electrical power of up to 2,2kW at 230V directly and to connect it to the LON field bus system. The control has a 2-pole main switch with an integrated overload safety fuse, as well as six potential-afflicted relays for a compressor, a cooling valve, oil sump heating, a ventilator, a defroster and light. Together with the separate clamp-strips for N + PE, this permits a fast and easy assembly without any additional wiring.
A potential-free alarm relay with adjustable switching sense and two analogue inputs for temperature sensors are standard. A special characteristic, however, are the four digital switching inputs to register the external switching status of pressure and interactive switches. In connection with the freely adjustable functions of the control, the latter, for example, is intended for the pump down operation mode and other applications. The LON interface FTT10 permits communication with super-ordinate systems.
The delivery programme includes two PTC temperature sensors with a cable length of 4 meters each.
