Introduction
The I-87028CW is an 8-channel current output module that features channel-to- channel isolation and also has qualification for 4 KV ESD protection and 1000 VDC intra-module isolation. Options for configuring power-on and safe values are also included.
The I-87028UW is a source type analog output module that includes 8 single-ended analog output channels, and allows a programmable output range on all analog outputs channels(0 ~ 5 V, +/-5 V, 0 ~ 10 V, +/-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. Voltage and current outputs are jumper selectable, and the module also features per-channel open wire detection for +4 ~ +20 mA outputs, together with 4 KV ESD protection as well as 2500 VDC intra-module isolation. Options for configuring power-on and safe values are also included.
Applications
Building Automation, Factory Automation, Machine Automation, Remote Maintenance, Remote Diagnosis, Testing Equipment.
