Galvanic isolation • Transmitter power supply or loop receiver • HART protocol feature • Galvanic isolated output • DIN-rail mount, pull-out screw terminals • Pull-out power distribution by flat cable
PROF30-ISH galvanic isolations are designed to transfer a 4-20 mA current loop without electrical continuity and give transparency for “HART” numerical communications. This feature makes for numerous easy and safe inputs on DCS, while avoiding metrology problems on loop and more importantly destruction caused by common mode. PROF30 can supply a 2-wire transmitter and provide an analogue galvanically isolated recopy output. PROF30 have built-in independent housing, to be mounted on DIN rail 29 mm symmetric hat-profile. Connections are done through pull-out screw terminals. According to models, PROF30 need 48 to 230VAC or 24 VDC supply, dispatched by flat cables saving space and time during wiring, which provides maintenance flexibility.
