M5174P Description
Monolithic integrated circuit M5174P is designed for the use of the flame detection circuil. It is posed 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.
M5174P Key Features
- Fail-safe system (The operating mode of two degrees of redundancy.)
- Available input flame current
- 50,uA(max.)
- Minimumtollelance for operating threshold input current
