Highlights

• The Modbus RTU PWM Input 8CH is an isolated RS485 to 8-Ch PWM PWM input module, supports PWM pulse frequency and duty cycle detection. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS
• The inputs use high-speed optocoupler isolation and support high-frequency detection. Configurable device address (1~255), multi devices can be cascaded on RS485 bus
• Onboard voltage regulator, supports 7~36V wide range power supply. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference. Onboard watchdog, for stable output without crashing
• Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
• Rail-mount case design, support stacking combination, easy to install and safer to use. 3x LEDs for indicating the MCU status and signal transceiving status
