Current Transformers: EJH provides a family of current converters with patented technology. These modules are very reliable and high-accuracy class.
ET201
Loop-powered current transducer
ET201 is an AC current transducer (CT) for 4..20 mA current loops (loop powered 2 wires technology). The module's main features are high precision, extremely compact size and wide configurability: eight pre-calibrated ranges, DIP-switch selected. ET201 allows extremely low consumption and low output ripple and quick response to variations.

ET201DC
DC Current Transducer to DC current (4..20 mA - loop powered)
ET201DC is an isolated, contact-less loop powered direct current transducer. The device’s function and look are very similar to those of an active standard CT, but with the remarkable feature of measuring the continuous component of the pass-trough current. For its electrical endurance, ease of use and compact dimensions, the ET201DC fits every kind of current measurement to 40 Adc.

| Note: | Patent pending product (new inductive measurement technology) |
ET201DC100
Passive current transducer 100 Adc for 4..20 mA current loop
ET01DC100 is an isolated and passive, contact-less loop powered direct current transducer. The T201DC100 has functions and look very similar to a standard current transformer, but it has stress features of measuring the continuous current component that pass-through it. For its electrical endurance, ease of use and compact dimensions, the T201DC100 fits every kind of current measurement to 100 Adc.
