#1 VINCITORE

  • Configurable device address (1~255), multi devices can be cascaded on RS485 bus. Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. Supports DI/DO linkage control or DO toggle control
  • 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 & anti-electrostatic
  • The output utilizes Darlington transistors with optocoupler isolation, provides stronger driving capability with up to 500mA sinking current, built in flyback diode protection. Rail-mount case design, support stacking combination, easy to install and safer to use
  • Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the output for a while and then close it automatically. Multiple LEDs for indicating the input & output status, MCU status and signal transceiving status
