The ET-2228CI is Channel to Channel Isolation analog output module that includes 8 differential 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 programmable 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 3750 VDC intra-module isolation. Options for configuring power-on and safe values are also included.
The ET-2224CI has the same specifications as the ET-2228CI but provides 4 differential analog input channels.
