Características
GL7-M
10 canales, termopar de voltaje y amplificador RTD, alto aislamiento por canal, 100 muestras / sa 1 muestra / h, 20mV a 50V F.S. y 1-5V F.S.
Módulo de entrada múltiple universal de 10 canales de temperatura / voltaje para termopar, RTD y señales de entrada de voltaje escalado. Para un entorno mixto de prueba y monitoreo que requiere varios datos de medición física, el GL7-M funciona como una solución de plataforma de datos muy útil. Max 10 módulos por unidad principal GL7000. Se puede lograr un intervalo de muestreo de 10 ms (100 muestras / seg) para las 10 unidades (100 canales) y sincronizar hasta 5 unidades GL7000 con 10 módulos cada una para un sistema máximo de 500 canales. El rango máximo de voltaje de entrada es 60Vp-p.
