+86 153594082755 A Genset Controller · Woodward easYgen-1500 Series
Woodward 8440-1809 easYgen-1500-55B is the 5 A current-input variant of the panel-mounted easYgen-1500 generator-set controller. Official product specification 37180 identifies the part number and provides the electrical, mechanical, environmental and ordering data for this exact model.
Woodward 8440-1809 easYgen-1500-55B combines engine start/stop sequencing with generator measurement, alarm and protection functions for compatible single-genset applications. The installed configuration determines sensing ranges, discrete I/O behavior, engine interface and breaker-control logic.
The controller uses a 186 × 138 mm panel cutout and has overall dimensions of 219 × 171 × 61 mm. The front reaches IP54 with clamp fastening or IP65 with screw fastening, while the rear is IP20; approximate unit weight is 800 g.
When replacing Woodward 8440-1809 easYgen-1500-55B, verify the 5 A CT circuits, voltage sensing, supply, terminal assignments, panel sealing method, firmware and saved configuration. Compare protection thresholds, engine timers, breaker logic and alarm outputs before returning the genset to automatic service.

Woodward 8440-1809 easYgen-1500-55B is the easYgen-1500 model with 5 A current-transformer inputs. The complete 55B designation and part number separate it from the 1 A variant and must be confirmed on the nameplate.
Woodward 8440-1809 easYgen-1500-55B is intended for compatible single-generator control applications combining engine sequencing, electrical measurement, alarms and protection. The configured I/O and breaker logic must match the engine, generator and switchgear design.
Woodward specification 37180 gives a 186 × 138 mm panel cutout and 219 × 171 × 61 mm overall dimensions for Woodward 8440-1809 easYgen-1500-55B. Confirm rear clearance, terminal access and gasket condition before installation.
The front of Woodward 8440-1809 easYgen-1500-55B is listed as IP54 with clamp fastening or IP65 with screw fastening when professionally installed. The rear is IP20 and therefore requires protection inside a suitable control panel.
Verify supply, protective earth, 5 A CT secondary wiring, generator voltage sensing, phase relationships, engine I/O, breaker circuits and output loads before energizing Woodward 8440-1809 easYgen-1500-55B. Never open a live CT secondary.
Restore only the correct configuration for Woodward 8440-1809 easYgen-1500-55B, verify measurement scaling and engine timers, then function-test start/stop, alarms, protections, breaker commands and emergency shutdown before enabling unattended or automatic operation.
No direct substitution should be assumed. Woodward 8440-1809 easYgen-1500-55B uses 5 A CT inputs, while the adjacent variant uses 1 A inputs. CT circuits, part number, configuration, terminal assignments and protection scaling must match.
Provide the complete part number, easYgen-1500-55B designation, revision, serial number, firmware, configuration file, CT ratio and secondary rating, generator voltage, panel fastening method and I/O drawings to validate the exact replacement.
Woodward product specification 37180 explicitly lists Woodward 8440-1809 easYgen-1500-55B and provides ordering, dimensional and technical information. Use the applicable operating manual and saved site configuration for detailed installation and commissioning values.
