High Accuracy 8Channel Modbus RTU PWM Pulse Input Module Supporting 30V Input And RS485 Communication Interfaces Multicolor

Features: High Precise 8Channel Input with 0.01 resolution and ±5‰ accuracy, supporting frequency detection from 400Hz to 50KHz and 0-100% duty cycle for industrial equipment monitoring. Isolated RTU Communication features RS485 interfaces with rate (4800-256000) and address configuration (1-255), enabling seamless bus cascading and host computer connectivity. Industrial Grade Protections integrates power/magnetic/opticals isolation with TVS tubes and selfrecovery fuses. Wide Voltages Compatibility operates on DC7-36V power supply, accepts 3.3V-30V inputs, and incorporates watchdog circuit with reverse polarity protections for stable continuous operate. DIN Rails Mounting Design with stackable structure, 3status LEDs for monitoring, &35mm rails installation for efficient industrial deployment.
