features and benefits
The I-87017RCW is an 8-channel current input module that is specifically designed to measure current only.
Its user-friendly design saves both time and effort when measuring a current thanks to a built-in resistor, meaning that current can now be measured directly.
The I-87017RCW is much more suitable for critically harsh environments since it also has 4 kV ESD protection and +/-200 VDC common voltage as current input protection, and also features 3000 VDC intra-module isolation together with open wire detection for +4 to +20 mA input.
The sampling rate for the I-87017RCW is adjustable, meaning that either fast mode or normal mode can be selected.
- 8 Current Input Channels
- ±200 VDC Common Voltage Protection
- Supports both Fast and Normal Mode Sampling Rates
- Overcurrent Protection
- Built-in Resistor to simplify Current Measurement
- Open Wire Detection for +4 to +20 mA input
