It also provides a programmable analogue output range (0 ~ 5 V, +/-5 V, 0 ~ 10 V, +/-10 V, +4 ~ +20 mA or 0 ~ +20 mA), and each analogue output can be configured for an individual range.
The output value for each channel can be set to be stored before the module is powered down, so the last output value can be restored when the module is re-started. The options for voltage or current output of the I-87028UW are selectable via jumpers.
The module also features per-channel open wire detection for +4 ~ +20mA output. Together with 4 KV ESD protection as well as 2500 VDC intra-module isolation, and provides an RF immunity level matching that defined by the IEC 61000-4-3 standard.
This current output module is made for use in industries such as building automation, factory automation, machine automation, remote maintenance, remote diagnostics, and for testing equipment.
