The DT1623 Ix… AC current transmitters produce a square wave output with a frequency range of 400–2000 Hz,
proportional to the true root mean square (TRMS) of the input signal, for the processing unit.
By using the frequency output – in the case of a PLC signal processor – a costly analog input can be replaced with a
counter input.
The devices can be operated with a 24 VDC power supply.
The inputs of the transmitters are separated from the network to be measured by a broadband measuring transformer.
The inputs comply with the requirements of the CAT III measurement category.
The devices can be ordered in three versions with 6 measuring ranges, according to the type table above. Within the given type, the measuring range can be selected with the front-panel “Hi-Lo” switch.
The inputs can be permanently overdriven up to twice the nominal measuring range.
In the I5/1 measuring range version, the current to be measured can be connected via a terminal block, in the higher measuring ranges, the current to be measured wire must be threaded through the opening in the box.
A green indicator on the front panel indicates the operating status of the device, a continuous light indicates correct operation, a flashing light indicates an error status.
The device is designed as a terminal block, width: 17.5 mm.
The transmitters fully comply with the requirements of the EN 60688 standard.
