GENERAL DESCRIPTION
The thermocouples or mV-level signal from the hazardous field is picked up by this product, converted to the standard current or voltage signal which is isolated with the hazardous area and transmitted to the control cabinet, PLC, DCS, display meter etc.. The product is equipped with cold junction compensation. Furthermore, it is armed with RS485 digital bus interface, which makes network configuration and the input or output configuration possible in many application fields. It is an intelligent safety barrier, and the type or range of the thermocouples can be set through the host computer, moreover, cold junction compensation can work automatically.
FEATURES
● 3-port isolation (input, output and power
supply)
● High accuracy (0.1% F.S.)
(Accuracy decreases with the smaller
range)

● Isolation voltage
(Between Hazardous area and safe area:
2500VAC)
● Low temperature drift (35PPM/°C)
● Digital bus (RS485)
● Programmable input/ output
● Alarm indications
● High reliability(MTBF>1,000,000 hours)
● Surge protection
