    GENERAL CHARACTERISTICS The PMS-620N meter is equipped with one current input 0-20 / 4-20mA and one voltage input 0-5 / 1-5 / 0-10 / 2-10V. Current input has additionally overcurrent protection circuit, which protects standard resistor. The selection of active input is realized by software, and selected input can be changed at any time.
