25SU5 Controls Amplifier

Brand: Fireye, Inc

The Fireye Type 25SU5 Model Control, combined with remote Flame Scanners, comprises a repetitive self-checking flame safeguard system that confirms the flame presence and absence to provide reliable ignition and flame failure protection.

The Fireye 25SU5 Control enables the construction of integrated safety interlock systems for single and multiple burner fired apparatus including power, industrial process, and electric utility furnaces and boilers that fire gas, oil, pulverized coal or a combination of fuels on a continuous basis.

The 25SU5 Control may also be employed in the safety control circuits of supervised manual and semi-automatic burner management systems as the primary safety control.

This flame safeguard system monitors flame to supervise burner and pilot performance throughout the entire burner load range.
