MK33-LI-EX0
The single channel MK33-11Ex0-Li… loop isolators are used to operate intrinsically safe 2-wire loop powered transducers in explosion hazardous area and to transfer signals to the safe area.
The MK33-11Li-Ex0… types are single channel device with an input and output circuit of 0/4…20 mA. A green LED indicates that the device is powered.
The input circuit is isolated from the output circuit and from the supply voltage. Input signals are passed (1:1) without attenuation to the output located in the nonhazardous area.
Due to this function it is possible to connect this device to power supplying input circuits of a PLC and to install it in such applications which previously used Zener barriers.
Due to the 1:1 transmission characteristic of the loop powered transducer circuit, wire-break or short-circuit faults are shown as 0 mA or > 22 mA respectively.
For applications with HART® transducers, there are loop-isolaters available which not only transmit analogue signals but also transfer digital signals bidirectionally:
– IM33-11Ex-Hi/24VDC (page 3 – 43)
– IM33-22Ex-Hi/24VDC (page 3 – 45)
