Features At A Glance

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 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
Onboard watchdog, for stable output without crashing
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

Primary Function

Supports Sending Modbus RTU Protocol Commands Via RS485 To Acquire PWM Pulse Signals

Industrial Grade Isolated Protection

Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for industrial environments with high requirements.
