AC motor 7,5 A | 0-10 Volt control | TK monitoring

Transformer fan speed controller with Modbus RTU communication. Supply voltage is 115 - 230 VAC. The maximum motor current is 7.5 A The RTVS8 series is controlled via Modbus communication. The required fan speed can be set using Sentera HVAC sensors, potentiometers (SPV series), Modbus I/O modules or BMS systems. The fan speed can be controlled manually or depending on temperature, relative humidity, CO2 and air quality (TVOC). The fan speed is adjusted by gradually changing the motor voltage. Autotransformer technology produces a perfectly sinusoidal motor voltage. This ensures quiet operation of the motor. A special impregnated coating reduces electrical noise from the autotransformer. The housing can be surface mounted (protection class IP54).

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.
