Matching resistance: default NC, reserved 120R matching resistor, can be enabled by jumper cap. Wireless communication: 2.4GHz Wi-Fi (802.11 b/g/n), Bluetooth 5 (LE). – Relay channels: 1 channel. It integrates 2.4GHz Wi-Fi and low-power Bluetooth 5 (LE) dual-mode wireless communication, featuring excellent radio performance.

This product is an industrial standard isolated RS485 to PWM pulse output module. Four channels of frequency and duty cycle are independently adjustable. It adopts Modbus RTU protocol and includes built-in protection circuits such as power isolation, magnetic coupling isolation, self-recovery fuse, and TVS.

Onboard buzzer, RGB indicator light, power indicator, RS485 transmit/receive indicator, and CAN indicator for easy monitoring of device operational status. Output employs Darlington transistors with optocoupler isolation for enhanced drive capability, sink current up to 500mA, and built-in freewheeling diode protection.
