F3YD18-0N Yokogawa Transistor Output Module

Product Overview

The Yokogawa F3YD18-0N is an 18-point sink-type transistor output module for the FA-M3 series, providing high-current DC switching for industrial actuators and control devices. With 2A per point and 18A per common, it can directly drive solenoid valves, small DC contactors, and indicator lamps without external relay expansion. Fast 1 ms response time and photocoupler isolation ensure reliable, noise-immune operation in demanding automation environments.

FAQ

• Q: What is the maximum current per point? A: 2A per point with 18A total per common, allowing direct drive of most industrial 24V DC loads.
• Q: Can I switch AC loads with this module? A: No, F3YD18-0N is DC-only. For AC loads, use F3YC08-0C or F3YC16-0N relay output modules.
• Q: Does it have short-circuit protection? A: The module includes active clamp surge protection. For overload conditions, ensure external fusing or circuit breakers are sized appropriately.
• Q: What happens during a CPU error? A: Output behavior is configurable per group to either HOLD the last state or RESET to OFF during CPU failure.
• Q: Is this an official Yokogawa catalog model? A: F3YD18-0N is available through authorized Yokogawa industrial supply channels. For the closest officially cataloged equivalent, F3YD14-5A (14-point, 0.5A) is listed in FA-M3 general specifications.

Installation Guide

1. Power off the FA-M3 system and external 24V DC supply.
2. Insert F3YD18-0N into any available I/O slot.
3. Connect DC loads to the terminal block observing proper polarity for sink outputs.
4. Apply external 12-24V DC power to the module power terminals.
5. Configure CPU error response (HOLD/RESET) via WideField3 as required by your safety strategy.
6. Restore power and test each output channel via ladder logic or monitor function.
7. Verify load currents do not exceed 2A per point or 18A per common.

Selection Tips

• Use F3YD18-0N when you need 18 high-current transistor outputs (2A per point) in a single module.
• For 14-point applications at 0.5A, F3YD14-5A is the standard catalog equivalent.
• For 8-point high-current (1A) applications, F3YD08-6A offers a compact alternative.
• Always size the external power supply for total load current plus module overhead (10 mA).
• Use shielded cables and separate high-current wiring from sensitive signal lines to minimize EMI.
