Introduction

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