Temperature controller-archiver TCA4-2/220V

T=(-45,0º...+125,0ºC), Us=220Vac, Pt100, Output 4A/220V, 95x49x113mm

Price 139.13 EUR no VAT

The single-channel digital temperature controller-archiver TCA4-2/220V is a microprocessor device with a 4-digit display, which serves to measure, regulate and archive temperatures in the range from -45,0º to +125,0ºC. The temperature controller with data logger uses a Pt100 temperature sensor as a sensing element for measuring the temperature and it has one output relay. Temperature regulation is carried out by two-position law "on/off". The device is designed for installation in a dashboard (panel montage).

FEATURES

The digital single-channel temperature controller-archiver TCA4-2 is a compact microprocessor device which is used for archiving, measuring and regulating temperatures within the range from -45,0º to +125,0ºC. The temperature controller-archiver has one input and one output. The input of the device is designed for operation with a 2-wire or 3-wire temperature sensor Pt100, and his output is a relay contact. The temperature regulation is carried out in a simple two-position law of control (ON-OFF). The temperature controller-archiver has a built-in EEPROM memory saving the recorded current temperature and status of basic parameters (T, h, Mode) each minute in real time. The memory installed in the device allows storage of 8192 recordings (with an option of 16384 recordings). The temperature controller-archiver is designed for incorporation into an industrial network, working with RS485 a standard data exchange protocol on a two-wire line. On the rear panel of the archiver a “6P4C” telephone plug is mounted through which it communicates with a computer.

Short description

The single-channel digital thermal controller archiver TCA4-2 is an electronic device that serves for measuring, controlling and archiving temperatures in the range from -45,0ºC to +125,0ºC. The thermal controller archiver uses a Pt100 temperature sensor as a sensitive element for measuring temperature. The main purpose of the thermal controller archiver is to store the measured temperature for a certain period of time.
