RTA202F230 - RTA200 Series Temperature Controls For Heating

Temperature Control

RTA202F230 - Electronic Thermostat Range 65T95 °C, 230 Vac rta series electronic thermostats are ideal for all air-conditioning, refrigeration and heating applications where greater precision than that offered by an electromechanical thermostat is required. rta series features two models, available in various versions: - RTA200 with adjustable differential; - RTA202 with fixed differential and manual reset. Other characteristics of these instruments include: - the use of an NTC probe that can be installed up to 50 meters away, allowing a series of control functions to be included in just one electrical panel, avoiding the need for expensive sealed devices; - compact and modular dimensions (dimensions and measurements to DIN standard). These represent an ideal economical solution for air-conditioning and refrigeration applications. They allow the user to install a series of control functions in the electrical panel, without requiring expensive sealed devices; in fact, these can be connected to any CAREL NTC probe with remote installation of up to 50 meters. The model RTA202* is specifically used in applications where a safety thermostat with manual reset is required, for example, in water-cooled chillers as the anti-freeze thermostat. They also have extremely compact dimensions (2 DIN modules) and feature DIN rail mounting.
