AC motor 10 A | pressure control: 0 - 2.000 Pa | TK monitoring

This electronic fan speed controller provides precise fan speed regulation for 230 V single-phase motors with a maximum current of 10 A. It features an invertible analogue input signal, accepting either 0-10 / 10-0 VDC or 0-20 / 20-0 mA. It also includes a remote control input with selectable functionality (normal or timer), as well as an analogue input with normal or logic functionality for timer-based starts. The minimum and maximum output voltage can be set by internal trimmers or via Modbus RTU communication. The off value is also adjustable by trimmer or via Modbus. The device supports both kick start and soft start modes. It has one regulated output for the motor, one unregulated output (230 VAC / max. 2 A) for a 3-wire motor connection or voltage supply, and a low voltage supply output (+12 VDC / 1 mA) for an external 10 kΩ potentiometer. The device provides clear status indicators with a green LED for normal operation and a red LED for overheating. It also features an alarm output (230 VAC / 1 A) and is designed for DIN rail mounting.

Differential pressure controller with display for fans. A typical application is Variable Air Volume flow or VAV control. The supply voltage is 24 VDC. The operating range is 0 to 2.000 Pa. It controls fan speed to maintain differential pressure or air volume flow constant at the set point. Air velocity control is also possible in combination with a Pitot tube connection set: PSET-PTX. The setpoint can be adjusted via Modbus RTU communication. The sensor output controls EC fans, frequency inverters or AC fan speed controllers via 0-10 V. Another output type can be selected if necessary. The 7-segment LED display and the four LED indicators provide a clear visual indication of the transmitter status and the controlled values. The differential pressure setpoint and all other settings can be adjusted via Modbus RTU.

This 24 VDC switch mode power supply is DIN rail mounted and features a built-in Modbus RTU repeater. It offers protection against short circuit, overload and overvoltage. The maximum load is 900 mA or 20 W. The 24 VDC supply is only available via the output channel. All devices can be connected via terminal blocks or via the RJ45 connectors. The Modbus RTU communication of both channels is reinforced by the built-in half-duplex line repeater. The supply voltage is in the range of 85 to 264 VAC (50-60 Hz). This device is mounted on a DIN rail. The enclosure offers an IP20 protection against ingress of dust.

Set of nozzles and PVC tubes to connect a differential pressure sensor or controller to the ductwork. It contains 2 plastic nozzles (L 66.6 mm, D 6 mm) and 2 flexible, transparent PVC tubes with a length of 2 m and a maximum working pressure of 10.000 Pa. The screws to fix the nozzles in standard ductworks are also included. This set is designed for HVAC applications and can be used in combination with differential pressure transmitters, controllers or switches.
