Controller for distributor assembly (hat rail) ITR 79 remote sensor, electronic

Technical data

Application

Housing colour:

grey, like RAL 7035

Control and monitoring of the tem- perature in large halls, greenhouses and floor heating systems. The de- vices have sensor rupture and sensor short-circuit protection. Sensors are not a part of the deliv- ery scope (except for ITR 79.804) For available sensors, see the ‘Sen- sor Technology’ chapter. Use sensors according to the speci- fied sensor number (for example, for sensor number 4: all sensors with this number can be used, e.g., KF-4). Avoid parallel routing of sensor wires together with mains voltage-bearing wires ore use shielded wires.

Ambient temperature: Permissible atmospheric humidity:

−10 … +40 °C

Max. 95% rel. humidity, non-condensing

Operating voltage:

230 VAC, 50 Hz

Max. switching current:

NO contact: 10 (2) A, NC contact: 5 (1.5) A The resistance of the contact transi- tion results in a voltage drop across the contact. This can have a strong influence on very small switching signals.
