Art. no.: 37256
CXE/AV Control Modul
Speed control unit for up to 2 fans for the following functions:
- Temperature control
- volume flow control
- pressure control
- Air velocity control
Integrated voltage supply for sensors: +24 V, max. 70 mA
Integrated analog outputs A1 and A2: 0-10 V, Imax 10 mA (short-circuit-proof)
Maximum load of relays K1 and K2: AC 250 V / 2 A
Maximum ambient temperature: +55 °C
Interference emission according to EN 61000-6-3
Interference immunity according to EN 61000-6-2
Setting of the desired speed through device or by external default, e.g. 0-10 V
Connecting pressure sensors (refrigeration), measuring range 0-30 bar, 0-50 bar
Connecting temperature sensors, device measuring range -27...+75 °C, Sensor measuring range -10...+120 °C
Connecting differential pressure sensors (air conditioning), measuring range 0-6000 Pa, acquisition of volume flows up to 65,000 m3/h
Connecting air velocity sensors, measuring range 0-1 m/s, 0-10 m/s
Connecting additional sensors, e.g. combination sensors, CO2, sensor signal 0-10 V / 0-20 mA / 4-20 mA
Several sensors can be combined with the CXE/AV universal control module. The actual value measured at the sensor is compared with the setpoint. This results in the 0-10 V output signal. Two 0-10 V outputs are integrated. These serve to activate EC fans, frequency inverters or other devices.
Optionally, connected field devices (frequency inverters/EC fans with plugged MODBUS add-on module) can be activated by the integrated MODBUS-RTU interface (MODBUS Master function). The device also contains two separate control circuits, a real time clock and timer functions.
The universal control modules are especially suitable for the following applications: Refrigeration, air conditioning, general ventilation tasks, clean room technology. For typical applications in the areas mentioned, fast start-up is possible by selecting pre-programmed operating modes.
