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 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

does work automatically.

One independent power supply is required. Moreover, within

the product power supply, input and output are mutually isolated.

Field devices connected and regions:

J, K, T, E, S, B thermocouple, millivolt signal sensor;

Zone 0, Zone 1, Zone 2, IIA, IIB, IIC, and hazardous area of

T4~T6.
