The 369B1844G5004 (MDO53) is a 16‑channel relay‑based discrete output module engineered by GE for the Nexus and Nexus OnCore control platforms. Each channel on the 369B1844G5004 provides a dry relay contact capable of switching up to 12 A resistive AC loads at 250 V, directly driving contactors, solenoid valves, annunciator panels, and motor starters. The 369B1844G5004 operates from a 24 V DC system power supply and includes per‑channel LED status indicators, channel‑to‑channel isolation at 1000 V AC, and 3000 V AC isolation to system backplane. With removable Euro‑style terminal blocks and a compact screw‑mount form factor, the 369B1844G5004 simplifies field wiring and maintenance in demanding industrial environments.
Gas and steam turbine control – fuel valve actuation, trip circuit management
Boiler control and burner management systems (BMS)
Emergency shutdown systems (ESD) requiring high‑integrity relay outputs
Motor control centers (MCCs) – direct switching of contactors and motor starters
Power generation balance‑of‑plant (BOP) equipment control
Oil and gas pipeline valve control and compressor station logic
Industrial automation – conveyor systems, pumps, agitator control
Hazardous location installations (Class I Division 2 / Zone 2) – with IECEx certified variants
16 high‑current relay outputs: Each channel is an independent dry contact relay rated for 12 A resistive AC loads, eliminating the need for external interposing relays in most applications.
Per‑channel LED diagnostics: A dedicated green LED for every output channel indicates the real‑time relay state — instant visual confirmation of load energisation status during commissioning and troubleshooting.
High galvanic isolation: 1000 V AC channel‑to‑channel, 2500 V AC channel‑to‑ground, and 3000 V AC channel‑to‑system — blocks cross‑talk, surge transients, and ground loops in high‑EMI environments.
Removable Euro‑style terminal block: Front‑accessible, 16‑pin spring‑clamp or screw terminal block allows complete disconnection of field wiring without de‑terminating individual conductors — simplifies module replacement.
Redundant 24 V DC power reception: Draws operating power from dual redundant 24 V DC system rails; if one power source fails, the module continues uninterrupted operation from the remaining healthy supply.
Transient suppression ready: Relay contacts are prepared for optional snubber networks or varistors; users can add suppression components directly to the terminal block for inductive load switching (contactors, solenoids) without external interface modules.
Industrial temperature tolerance: Operates reliably from 0 °C to +60 °C with storage capability down to –40 °C — suited for turbine enclosures, outdoor cabinets, and unheated industrial buildings.
Hazardous location certification: Available in variants with IECEx / Class I Division 2 approval for installation in potentially explosive atmospheres (gas zones, refineries, fuel handling areas) when housed in appropriate enclosures.
Executes discrete control commands from the Nexus iDPU controller by closing or opening the 16 built‑in electromechanical relays, thereby energising or de‑energising field devices.
Electrically isolates the low‑voltage control circuitry from the high‑power field loads via relay contacts and optical isolation, protecting sensitive electronics from voltage spikes.
Provides immediate feedback to the control system through relay state detection circuits and LED indication, enabling the controller to verify that commanded outputs are actually executed.
Drives both AC and DC loads from the same output channel, reducing the need for separate AC/DC interface modules in mixed‑load control cabinets.
Maintains output states during controller scan updates; the module latches the last received command until a new instruction arrives, ensuring stable load control without output chatter.
Performs continuous self‑diagnostics of relay coil integrity and contact operation; any discrepancy triggers a module‑level fault LED and reports status back to the iDPU controller for annunciation.
Q1: What is the 369B1844G5004 used for?
A1: The 369B1844G5004 is a 16‑channel relay output module that drives field actuators such as contactors, solenoid valves, annunciators, and motor starters in GE Nexus OnCore control systems.
Q2: How many output channels does the 369B1844G5004 provide, and what is their switching capacity?
A2: The 369B1844G5004 provides 16 independent AC relay output channels. Each channel is rated for 12 A resistive / 7.5 A inductive at 250 V AC, or 12 A resistive / 6 A inductive at 30 V DC.
Q3: Does the 369B1844G5004 require an external relay board?
A3: No. The 369B1844G5004 (MDO53) integrates 16 electromechanical relays directly on the module, so external relay boards are not needed. However, when large‑capacity DC control circuits are required, an extension relay board may be added.
Q4: What isolation ratings does the 369B1844G5004 provide?
A4: It provides 1000 V AC channel‑to‑channel, 2500 V AC channel‑to‑ground, and 3000 V AC channel‑to‑system isolation for reliable performance in high‑voltage industrial environments.
Q5: Is the 369B1844G5004 hot‑swappable?
A5: The 369B1844G5004 does not support live insertion. The module should be installed or removed only after the connected 24 V DC system power has been de‑energised to avoid damage to relay contacts or backplane circuits.
