Other AbstractThe invention relates to a fault-state cutoff protection circuit for a safety instrument transmitter. Specifically, the invention relates a safety instrument transmitter suitable for industrial process control, and a fault-state cutoff protection circuit thereof. In terms of function, when dangerous invalidation occurs to the safety instrument transmitter, the protection circuit switches a power-supply circuit of the safety instrument transmitter from a normal work state to a safe state, that is, cuts off the power-supply circuit of the safety instrument transmitter. In terms of system structure, the fault-state cutoff protection circuit of the safety instrument transmitter includes the power-supply circuit and the protection circuit which includes devices such as a reference voltage device, D triggers, a reset management device, an or gate device, a diode, a triode and a field-effect tube and the like. The fault-state cutoff protection circuit for the safety instrument transmitter has the characteristics of being low in power consumption, high in universality and stable and reliable and the like.
