Honeywell U2-1010S-PF Flame Detector

The Honeywell U2-1010S-PF is a sophisticated flame detector designed for critical fire safety applications in industrial environments. This detector utilizes advanced sensing technology to provide reliable and rapid detection of various types of flames, ensuring the safety of personnel and equipment.

Input Power Supply: 22-26 VDC, 120 mA max (approximately 3.5 watts)

Remote Communication: 2 wire RS485 compatible with Modbus RTU protocol.

Flame And Fault Relay Contact Ratings:1 A, 30 VDC (Resistive).

U2-1010S-PF Maximum load current of 1A must be de-rated at temperatures higher than 50C ambient according to 1%/C, or 10mA/C. For example, the maximum current at 70C = 1A – (20C x 10mA) = 0.8A

U2-1010S-PF:

500 Ohm Load Max

File Select Input logic high: 21VDC min

File Select Input logic low: 16VDC max

U2-1010S-PF Ambient temperature: -40 to 70 ºC (-40 to 158 ºF)

Enclosure: IP66

Weight: 2.8 kg (6.1 lbs)

Physical Dimensions: Diameter: 11.7 cm (4.6 inches)

Length: 15.5 cm (6.1 inches)

Finish: Silicone free powder coated

The U2-1010S-PF model viewing port is designed for interface to a

1" NPT (M) fitting. The viewing head can be mounted in any orientation, any angle, upward or downwards.

It is recommended that earth ground is applied at the labeled earth ground screw connection on the housing. It is recommended the drain wire be connected to earth at power supply.

To reduce noise interference from ignition transformer or other high voltage sources, make sure all high voltage cables are in good condition and are at least 300 mm (12") away from U2 wiring.
