Intrinsically safe relay circuit
WebThe ISS-105 is a “smart” five-channel intrinsically safe relay and pump controller. The ISS-105 can be configured for a wide variety of applications including alternating or non-alternating duplex, duplex separate pump stop (SPS), triplex and quadplex applications. It can be set up for pump-up or pump-down applications or can be used as a ...

WebJul 31, 2024 · An intrinsically safe circuit is a commonly used type of protection for equipment that is used in hazardous areas. This type of protection is used, for example, in explosion-protected measuring and control devices. Limitation of current and voltage in the circuit prevents excessive heat and the formation of ignitable sparks.
