KSA-2000-EX series explosion-proof isolation safety barrier

overview

The KSA-2000-EX series explosion-proof isolation safety barrier is an intrinsically safe explosion-proof electrical product designed according to the requirements of GB3836 and IEC61508 standards. The product uses high-quality semiconductor devices and SMT surface mount technology, and is widely used in intrinsically safe explosion-proof systems such as petroleum, chemical, metallurgical, and power industries. Not only can it be used in conjunction with various two - and three wire transmitters, two-wire intelligent (HART) transmitters, intelligent (HART) electromagnetic flow meters, electrical converters, electrical valve positioners, intrinsic safety solenoid valves, level switches, NAMUR proximity switches, symbol fieldbus (FF) protocol intrinsic safety instruments manufactured by multiple domestic and foreign instrument companies, but it can also be used in conjunction with simple equipment such as dry contact switches, thermocouples (J, K, T, E, B, S, etc.), strain gauges, and thermal resistors (Pt100).
