1、 Instrument Overview:

The WP-8000-EX series thermocouple isolation safety barrier receives thermocouple signals or other millivolt signals from hazardous areas on site, and after isolation and linearization processing, converts them into linearized DC signals for output to the control system or other unit combination instruments in the safe area.
Intelligent thermocouple isolation safety barrier. The thermocouple type and range can be configured and set.
This isolation safety barrier requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
2、 Features:
The thermocouple temperature transmitter isolates the output.
Intelligent, capable of on-site configuration settings, and can also select fixed thermocouple types and temperature range inputs.
Modular core design, no need for zero and full adjustment, automatic dynamic calibration of zero and automatic compensation for temperature drift.
Equipped with a working power indicator light.
Intrinsic safety input circuit Exia) IIC, input circuit overcurrent protection.
● Plug and unplug terminal block, DIN rail card installation.
3、 Main technical parameters:
