AC motor 5 A | 0-10 Volt control | TK monitoring

Transformer fan speed controller with Modbus RTU communication for manually or demand-based fan speed regulation. The supply voltage ranges from 115 to 230 VAC. It can be used for single-phase motors. The maximum motor current (combined) is 5 A. Modbus communication is used to control the RTVS8 series. To adjust the requested fan speed, a Sentera HVAC sensor, potentiometer (SPV series), Modbus I/O module, or BMS system can be used. The fan speed can be adjusted manually or automatically based on the temperature, relative humidity, CO2 and air quality (TVOC). The fan speed is controlled by gradually varying the motor voltage. The autotransformer technology produces a perfect sinusoidal motor voltage. This ensures that the motor runs quietly. The electrical noise from the autotransformers is reduced by a special impregnated coating. Surface mounting is possible (IP54 protection).

This analogue to Modbus converter is equipped with 8 analog inputs that are configurable through the Modbus RTU protocol. 4 out of the 8 inputs can be set to support the following types: 0-10 VDC, 0-20 mA or 0-100% PWM signals. The remaining 4 inputs can be configured to handle 0-10 VDC and 0-20 mA signals. The analogue input data is transmitted to Modbus RTU Input Registers. The module is powered by a 24 VDC Power over Modbus (PoM) supply, which means that both the power source and Modbus RTU communication are established through the RJ45 socket. This module is designed for easy installation on a DIN rail within an electrical cabinet.
