I-87022W-G CR ICP DAS Analog IO Modules

The I-87022W is a Sink Type Analog Output Module that includes 2 Analog Output channels, and provides options for configuring power-on and safe values. It also provides a programmable Analog output range (0 ~ +10 V, +4 ~ +20 mA or 0 ~ +20 mA), and each Analog Output can be configured for an individual range. The module provides an RF immunity level matching that defined in the IEC 61000-4-3 standard. Voltage or current output is jumper selectable, and the module also features per-channel open wire detection for +4 ~ +20 mA output, together with ±4 KV ESD protection and 3000 VDC intra-module isolation.
