M5174P Datasheet FLAME DETECTOR

Manufacturer: Mitsubishi Electric

General Description

Monolithic integrated circuit M5174P is designed for the use of the flame detection circuil.

It is composed of current amplifiers, a thyristor circuit, a couple of the relay drivers and a internal voltage regulator.

The current limiting circuit of the driver and internal two sets of shunt circuits parallely connected with relay protect the relay against the danger in an abnormal state of no signal flame.
