PLANT ENGINEERING

CONTROLLER FOR DISTRIBUTOR ASSEMBLY (HAT RAIL) ITR 79 REMOTE SENSOR, ELECTRONIC

TECHNICAL DATA

APPLICATION

Housing colour:

grey, similar to RAL 7035

Control and monitoring of the tempera- ture in large halls, greenhouses and floor heating systems. The devices have sensor rupture and sensor short-circuit protection. Sensors are not a part of the delivery scope (except for ITR 79.804) For available sensors, see the ‘Sensor technology’ section. Use sensors according to the specified 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 to +40 °C

Max. 95% rel. humidity, non-condensing

Operating voltage:

230 V AC, 50 Hz

Max. switching current:

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

Min. switching current:

Max. switching voltage: Min. switching voltage: Switching element: Switching contact: Electrical connection: Mounting / attachment:

230 V AC, 50 Hz

5 VAC, 50 Hz
