Descrição

WObit • Condicionador de sinal para strain gauge, saída 4-20mA, interface RS485

O WDT11-I é um transdutor universal para sensores de força de strain gauge. Graças ao conversor digital, o sistema permite-lhe medir com precisão a força e convertê-la num sinal de 4-20 mA e digital (RS485).

A interface RS485 integrada com o protocolo MODBUS permite a comunicação direta de um ou vários módulos com um PLC ou um painel HMI. É possível ligar até 32 módulos num único bus.

A configuração do módulo é feita através da porta USB e do software associado. Para além das definições do dispositivo, o software também permite visualizar os valores de medição actuais.

Características:

  • Medição a partir de um strain gauge (4 ou 6 fios)
  • Conversão de valores para unidades seleccionadas
  • Taxa de amostragem e filtragem de sinal configuráveis
  • Saída analógica: (0)4-20 mA
  • Interface RS485 com protocolo MODBUS
  • Conector USB para configuração do dispositivo
  • Botão incorporado e conetor de tara externo
  • Indicação do estado do LED
  • Fonte de alimentação do aparelho 12-24 VDC
  • Montagem numa calha DIN ou em suportes
