The sensor module for voltage measurement, current measurement and temperature measurement for the temperature sensor PT100 EXDUL-392 has four ground-related or two differential 16-bit A / D voltage input channels with bipolar input voltage ranges (+/- 0.63 V, +/- 1.27 V, +/- 2.55 V, +/- 5.1 V, +/- 10.2 V), as well as via 2 bipolar current inputs (+/- 20mA), which are adjusted to 4..20mA. For temperature measurements with PT100 sensors, the module has 3 measuring units, each with its own power source and measuring inputs. The conversion initiation including the associated configuration of the A / D components (area / channel selection) takes place via software command.In addition, the module has a digital input and a digital output with galvanic isolation via high-quality optocouplers and additional protective diodes. Special high-performance output optocouplers can handle a switching current of up to 150 mA. The module is supplied with the necessary operating voltage via USB or an external voltage source.
