The Yokogawa VMA0055 is a dc voltage and current measurement and simulation module for use with the Yokogawa YPC 4000 Series multi-function tester. The module features the functionality of a DVM and loop calibrator for terrific versatility. When used with other YPC functions, the VMA / YPC combination provides valuable functionality not available in other devices. Measurement ranges include ±500 mV, ±55 V, and ±100 mA. Sourcing capabilities include ±1000 mV, 0 to 24 V and 0 to24 mA. The VMA module will also simulate transmitter outputs when connected to a loop or it can be used to temporarily supply 24V dc loop power to unpowered devices during commissioning or calibration activities.
The Yokogawa VMA0055 goes far beyond the ±50 volts / mA measurement capability of the YPC base unit and has its own isolated power supply so common ground problems are not an issue.
