The IRIS uniscan Ex is a fail safe flame monitor and amplifier, mounted completely into one enclosure. Its purpose is to monitor gas or oil flames in process heaters, or the smaller utility boilers. The operating voltage range is 18 to 27VDC, so that losses or fluctuations in the voltage have no effect within these parameters. The flame on output is a 24VDC signal. As well as gain and drop out time adjustments a high band pass filter with four positions is provided for better discrimination. A DIN rail mounting power supply module, to provide a 24VDC output from a 115/230VAC input is available if required. A commissioning module is also available. It is battery powered, and is capable of powering the UNISCAN on the boiler front for approx. one hour. This enables an evaluation on performance, without the need for separate power supplies and wiring.
