DC/DC ConverterHK_S Series Physical Specifications EMS ESD IEC/EN61000-4-2 Contact ±8KV perf. Criteria B Design Reference 1. Ground Loop Problem In Signal Transmission And Ground Electric Potential Difference There are many reasons causing ground loop problem in instrument circuit, when the signal transmission and receiving devices connected to different location or different power supplies, it will lead to ground loop, which is common in long cable transmission. Most of the reason is that the equipment of the metal shell had physical contact with the ground, so that ground loop produces...

DC/DC Converter HK_S Series In the circuit of fig. 1, Sensor signal is converted into digital signals through the ADC, then sent to the current loop DAC and HART modulator through MCU, and form 3.5~20 mA signal output. Current loop DAC get power supply from the PLC bus of output 3.5~20 mA, and output 3.3 V and 2.5 V through the built-in voltage regulator, supply a small amount of power for MCU and HART modulator. In the transmission of fig. 1, there are ground electric potential differences between two-wire system instrument and PLC on the far side, causing the common mode interference. The disturbance...
