Característica:

RTU modbus Rs485

4 Canales de entrada optoacoplados

4 Canales de salida a rele

Alimentación 12V

Comunicación de retransmisión: comunicación de red 485 de múltiples unidades, basada en el protocolo MBDBUS-RTU, la dirección de comunicación predeterminada es 1, el usuario puede modificar la dirección por comando

IN1 - IN4 son utilizados por el interruptor. 485 lee el estado del interruptor, no la salida del relé de control de entrada.

1. S1 botón de reinicio

2. D5 con el indicador LED

Descripción:

Salida de relé de 4 canales (uno normalmente abierto y otro normalmente cerrado)

STM8S103F3 MCU

Aislamiento optoacoplador de 4 canales
