Product Description

Brief Description:

      This apparatus transmits the in thermocouple(TC) or thermal resistance(RTD) signal to isolated current or voltage signal in a circuit or two isolated circuits, and the input, output, and power supply are galvanically isolated from each other.

    It can be used together with modular instrumentation and DCS, PLC and other systems,to offer signal isolation, signal conversion, signal distribution, signal processing and otherfunctions to field instrument, thereby enhancing the immunity of automatic control system in the industrial production process, and ensuring system stability and reliability. This product has many varieties, such as 1 in/1 out, 1 in/2 out,,2 in/2 out, with input/output magnetic isolation.

    Compared with other similar products, this apparatus has the advantages of fast response time, low power loss and quite well temperature characteristics.


Panel light indication:

Light indicating: PWR (green) remains shining during normal operation;

Light indicating: ALM light glitters (red) at occurrences of input signal fault, and remains shining at occurrence of input excess.


Input signal:

Thermocouple:K, E, S, B, J, T, R, N.

2/3-wire RTD resistance:Pt100, Cu100, Cu50, BA2, BA1 etc.

Signal type and range can be specified at your order and may also be programmed by user.
