features and benefits
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.
- 8-channel Voltage or Current Output
- Jumper Selectable Voltage or Current Output
- Individual Channel Configuration
- Open Wire Detection for Current Output
- Short Circuit Protection
- Power-on Value
- Safe Value
