1、 Product Overview
HCK981 high-precision two-wire signal isolator receives various current and voltage signals on site, transmits them through isolation, and outputs 4-20mA current signals. This isolator is powered by a two-wire circuit, with complete electromagnetic isolation between the input and output circuits. Mainly used for DCS and PLC systems for circuit power supply.
This isolator is made of ABS flame-retardant resin housing material, with a small volume, compact structure, and a housing thickness of only 6.2mm. The modular meter core design allows for low power consumption without the need for zero and full potentiometer calibration. Meets the requirements of IEC61000 for electromagnetic interference resistance.
