Mitsubishi FX2N-16EYT-ESS/UL Programmable Controller Extension Block
The Mitsubishi FX2N-16EYT-ESS/UL is a 16-point digital transistor output extension module designed for the MELSEC-F PLC architecture. Built specifically to deliver high-speed, contactless solid-state switching, this module features a source-type (PNP) output circuit configuration. It is engineered to interface directly with 5V to 30V DC field devices, solenoids, pilot indicators, solid-state relays, and digital actuators without mechanical contact degradation.
From a marine and harsh industrial automation standpoint, the FX2N-16EYT-ESS/UL provides noise immunity, vibration damping, and electrical isolation via optical coupling. It integrates seamlessly into automated power management systems (PMS), ballast control monitoring, emergency shutdown (ESD) circuits, and marine auxiliary automation.

Key Features
- 16-Point Solid-State Sourcing: Delivers 16 discrete transistor source outputs (5–30V DC), eliminating contact bounce and mechanical wear.
- High-Speed Switching Response: Under 0.2 ms response time for both OFF-to-ON and ON-to-OFF transitions, ideal for pulse-driven solenoid control and high-frequency actuation.
- Optocoupler Circuit Isolation: Complete photocoupler insulation between internal PLC logic and field terminal wiring, protecting main CPUs from external spikes and back-EMF surges.
- Independent Group Commons: Features isolated common groupings (4/8 outputs per common bank) with 0.5A per-point and 1.6A per-group ratings.
- Multi-Class Marine Type Approvals: Fully compliant with major marine classification societies (DNV, Lloyd’s Register, ABS, ClassNK, Bureau Veritas, RINA, Korean Register).
Cross-Reference & Alternative Part Numbers
- FX2N-16EYT-C: Equivalent 16-point transistor output block using ribbon cable connector headers instead of screw terminals.
- FX2N-16EYT-ESS: Non-UL certified designation of the identical hardware block.
- FX2N-16EYR-ES/UL: 16-point mechanical relay output equivalent (used for mixed AC/DC loads up to 2A/point).
- FX2N-16EYS: 16-point triac output equivalent (specifically for 85–242V AC inductive load switching).
Applications in Heavy Industry & Marine Systems
- Marine Power Management Systems (PMS): High-speed trip sequencing, diesel generator auxiliary actuator triggering, and synchronized bus-tie breaker commands.
- Pneumatic & Hydraulic Solenoid Banks: Driving 24V DC hydraulic directional spool valves, bilge/ballast pump valve solenoids, and emergency quick-closing valves (QCV) where mechanical relay pitting is unacceptable.
- Engine Room Alarm Monitoring Systems (AMS): Rapid switching for strobe beacons, audible klaxons, and discrete telemetry feedback to wheelhouse consoles.
- Packaging & Conveyor Machinery: Diverter gate solenoids, optical rejector actuators, and automated indexing tables requiring under 1 ms continuous duty cycles.
Frequently Asked Questions
What is the difference between FX2N-16EYT-ESS/UL and standard FX2N-16EYT?
The suffix -ESS/UL indicates that the module features source-type (PNP) transistor outputs with UL and cUL industrial safety approvals for global installations. The standard Japanese domestic model (FX2N-16EYT) is designed with sink-type (NPN) transistor outputs where the load is switched to the negative/0V rail.
Can I connect the FX2N-16EYT-ESS/UL directly to a newer FX3U or FX3G CPU?
Yes. The FX2N-16EYT-ESS/UL is backward and forward compatible with the FX3U and FX3G terminal-type PLC main units. It plugs directly into the right-hand expansion bus ribbon connector without requiring special firmware configuration.
What is the maximum switching frequency and current limit per channel?
Each output channel handles up to 0.5A DC (5–30V DC). The module achieves an ON/OFF transition time under 0.2 ms. The aggregate current draw must not exceed 0.8A across 4 grouped points or 1.6A across 8 grouped points on a shared common terminal.
Does this module require an external 24V DC power supply to operate?
The internal logic circuit is powered directly from the base unit’s 5V DC bus (drawing 100 mA). However, an external 5–30V DC power source must be supplied to the field terminal block (+V commons) to drive the external load circuits.
