The I-87022W is a type of sink module with 2 analog output channels that offers configuration options for power-on values and safe values. It has a programmable output range of 0 to +10 V, +4 to +20 mA, or 0 to +20 mA, and each channel can be set to a unique range. The module also has RF immunity matching IEC 61000-4-3 standards and allows for voltage or current output selection via jumper. Additionally, it includes per-channel open wire detection for the +4 to +20 mA output and provides ±4 KV ESD protection and 3000 VDC isolation within the module.
