Introduction

The M-7002 module features 16-bit resolution, 4 differential analog inputs, 5 digital inputs, and 4 Form A relay outputs.The analog channels on the module offer programmable input ranges of ±150 mV, ±500 mV, ±1 V, ±5 V, ±10 V, ±20 mA, 0-20 mA, and 4-20 mA, while the digital outputs can be set to provide an alarm with short circuit and overload protection.

Each analog channel can be configured individually and is protected against high over-voltage input up to 240 Vrms. The input type (voltage or current) can be selected via a jumper. The M-7002 offers two sampling rates: fast mode and normal mode. Additionally, The M-7002 is qualified for 4 kV ESD protection and has intra-module isolation of up to 2500 VDC.
