The IOM-PWM8 module is designed to control a fan, drives, and other devices using a pulse-width modulated signal and control the rotation speed using a pulse counter from a rotation sensor. Up to 8 devices can be connected to the module. PWM level, measured number of pulses, module configuration are transmitted via RS485 interface via Modbus RTU protocol in Slave mode.
