Introduction

The M-7022 is a 12-bit, 2-channel analog output module that provides current and voltage outputs. The module features 3000 VDC intra-module isolation, and the current output's power source can be either internal or external via a jumper. Options are also provided to allow power-on and safe values to be set. The M-7022 supports Modbus RTU and DCON protocols, which can be configured via software. There are also options for configuring power-on and safe values. All hardware specifications are the same as the I-7022.
