Introduction

The M-2228CI is an 8-channel analog differential output module with 3000 VDC channel-to-channel isolation. It provides a programmable output range on all analog output channels (0 ~ 5 V, 0 ~ 10 V, +4 ~ +20 mA, or 0 ~ +20 mA). Each analog output channel can be configured for an individual range and provides an RF immunity level matching that defined by the IEC 61000-4-3 standard. The module also features per-channel open wire detection for +4 ~ +20 mA outputs, together with 4 kV ESD protection as well as 3000 VDC intra-module isolation. Options for configuring power-on and safe values are also included.
