MultiTek DC Current or Voltage 4kV or 1.5kV Isolation Tranducers

M100-DA1 DC current input 4kV isolation
M100-DV1 DC voltage 20 mV...11.9V input 4kV isolation
M100-DV2 DC voltage 12 V....600 V input 4kV isolation
M100-DA1I DC current input 1.5kV isolation
M100-DV1I DC voltage 20mV...11.9V input 1.5kV isolation
M100-DV2I DC voltage 12 V...600V input 1.5kV isolation

These isolators isolate the DC input signal from the DC Output signal, which is directly proportional to the input signal. There are two levels of isolation offered, the M100-DA1 / DV1 / DV2 have 4kV isolation and the M100-DA1I / DV1I / DV2I have 1.5kV isolation. A wide range of both D.C. Current and voltage inputs are offered.
Typically these isolators can be used to prevent earth loops, which occur when a measuring source, that is earthed, is connected to a computer or data logger that is also earthed. Another common use is to provide isolation on the inputs to a PLC.
All of the above isolators have either A.C. or D.C.
Auxiliaries which means they have an advantage over loop powered units, in that if for any reason the output lead should become disconnected, the input will not be saturated.

1. Non standard inputs / outputs only as far as technically acceptable.
2. A.C. Auxiliary in range 57.7 to 450 volts
3. Calibration at temperature other than 23°C
