features and benefits
The “Z” version is another milestone in the development of I-87018 and a testament to excellence by ICP DAS R&D team.
I-87018ZW is specifically designed for extremely accurate thermocouple measurement.
It features automatic compensation for each channel.
Current input and voltage input are supported.
Another feature is that ten of its input channels can individually be configured with different kinds of analog input.
I-87018ZW also got open thermocouple detection and many protection mechanisms.
- Current Input, Voltage Input and Thermocouple Input
- 240 Vrms Overvoltage Protection
- Individual Channel Configuration
- Open Thermocouple Detection
- Temperature outputs consistency
- Stable temperature output in the field
- 3750 Vrms Photo Isolation
