Fireye 4-128-1 Firetron Cell 320735-701 Fail-Safe Reliability: The spring return

Fail-Safe Reliability: The spring return mechanism ensures the system returns to a safe normally closed state if power is interrupted

Its direct-mount design allows for seamless integration into high-pressure lines

such as exhaust damper controls

The equal percentage characteristic compensates for the non-linear heat transfer of coils

Fireye 4-128-1 Firetron Cell 320735-701 Fail-Safe Reliability: The spring returnThe Fireye 4 128 1 Firetron Cell is a high sensitivity cadmium sulfide photocell engineered exclusively for use with the Fireye 48PT1 lead sulfide infrared scanner. Designed for precise flame detection in industrial and commercial burner applications, this component monitors infrared radiation emitted by combustion. The 4 128 1 operates as a resistive element that decreases in resistance upon exposure to infrared energy, providing the primary signal
