Signal Converter from Delta Ohm

Signal Converter HD 588

THE HD 588 MODULAR SIGNAL CONVERTER WITH 3-WAY GALVANIC SEPARATION FOR THE PROCESSING OF ANALOGUE SIGNALS
0-20mA
4-20mA
0-10V

Built inside a 2-module DIN box for 35 mm asymmetric guide, the converter offers, as well as a conversion of analogue signals between input and output, a complete galvanic separation among input, output and power supply. The 3-way circuital configuration ensures a definite decoupling of the sensor circuit from the external control circuit, preventing reciprocal influences in the presence of various measuring circuits.

The HD 588 converter module is made up of the following sections:
- Universal input stage with signal conversion from voltage into frequency.
- Universal output stage with signal conversion from frequency into voltage.
- Power supply stage.

Configuration can be modified through jumper connections, an important feature being the possibility of modifying the type of input and output without having to calibrate the converter again. By simple operations the HD 588 converter allows up to 9 different combinations between input and output.

Signal Converter HD 978TR3 - HD 978TR4

HD978TR3 and HD978TR4 are signal converters/amplifiers that can be configured
using mV input. The mV input signal range can be configured from -10mV to +60mV through a button, by using the HD778-TCAL simulator and the DeltaLog7 software or a gauge with mV output. HD978TR3 has a 4-20mA current output. HD978TR4 has a 0-10Vdc voltage output, with 0-1Vdc, 0-5Vdc and 1-5Vdc outputs available upon request.

A led signals the alarm situations and helps the user during the programming phases. The tool is also protected against polarity inversion.

The input and the output are electrically isolated so as to eliminate the problems caused by the reciprocal influence of the devices originating in the disturbances caused across the various grounding/earthing routes.

The tool is housed in a 2 DIN module container (width 35 mm) with normalized connection for 35 mm omega bars.The 4-20mA current output stage of HD978TR3 is a two-wired passive type and supplies power to the converter through the same current loop.
