features and benefits
The I-87017RW is an analog input module with an extremely high-quality protection mechanism where the overvoltage protection can be as high as 240 Vrms.
The input type can be set to either voltage or current.
The I-87017RW is an upgraded version of I-87017W, with the only differences being that the I-87017RW is more suitable for critically harsh environment.
The sampling rate for the I-87017RW is can be adjusted to either fast mode or normal mode depending on individual requirements.
The I-87017RW also provides 4 kV ESD protection as well as 3000 VDC intra-module isolation.
- 8-channel Analog Input
- Voltage or Current Input
- 240 Vrms Overvoltage Protection
- Adjustable Sampling Rate
