Conversion of the output voltage (0...+10 V) into an output current (0...20 mA or 4...20 mA) is possible with option VME- DAC812-20mA for 4 or 8 channels. Software Support Simple commands control the VME-DAC1612 via VMEbus so that no driver is necessary. However, drivers for all popular Electrical Isolation operating systems are available. Fast magnetic coupling barriers IL715 and DC/DC-converters perform the electrical isolation between VMEbus and analog process section. growing with the Wiring The P2 connector links both the external power supply inputs of the analog section and the process signals to the system. esd challenge Phone: 800-732-8006 • Fax: 800-732-8093 • Web: http://www.esd-electronics-usa.com• Email: us-sales@esd-electronics.com esd electronics, inc.
