The PRG-1200-H operating end isolation safety barrier is suitable for intelligent (HART) valve positioners, electric/gas converters, etc. It transmits standard 4mA~20mA current signals from the safety side to the danger side, driving the on-site actuators to work. At the same time, the HART digital signal communicates bidirectionally between the safe and dangerous sides, and can be operated on intelligent (HART) valve positioners, electric/gas converters, etc. using a HART handheld device on both the safe and dangerous sides. This product requires independent power supply, with full isolation between the power supply, input, and output.
