by ICP DAS
|
|
|
|
Modbus RTU Based Data Acquisition Module With 6 Analog Inputs, Current Input
(±150mV, ±500mV, ±1V, ±5V, ±10V, ±20mA, 0-20mA, 4-20mA), 2 Analog Outputs, 3
Digital Inputs (with Counter) and 3 Digital Outputs. Supports Operating Temp

The M-7026 is a Modbus RTU based multifunction module with 6 analog inputs, 2
analog outputs, 3 digital inputs, and 3 digital outputs . It provides a
programmable input range on all analog inputs (+/-150 mV, +/-500 mV, +/-1 V,
+/-5 V, +/-10 V, +/-20 mA or 0 ~ +20 mA). The analog outputs are 12-bit at +/-5
V, +/-10 V, 0 ~ +20 mA or +4 ~ +20 mA. All digital outputs can be set as alarm
outputs. Each analog input can be configured for an individual range and
provides a high overvoltage protection of 240 Vrms. Voltage and current
inputs/outputs are jumper selectable.
