FS-MC8N Keyence Multi-Output Unit for FS-N40 Series NPN

Keyence FS-MC8N Multi-Output Unit for FS-N40 Series

Core Technical Specifications

• Brand: Keyence
• Model: FS-MC8N
• Series: FS-N40
• Type: Multi-output unit
• Output type: NPN
• Separate control outputs: 8
• Common output: 1
• Common input: 1
• Unit expansion: Up to 8 expansion units; dual-output units count as 2
• Allowable passing current: 1,200 mA or less
• Indicators: STATUS (green/red), MEMORY (orange), LOCK (orange)

I/O and Signal Behavior

• Control output runs as NPN open-collector and handles 30 V max.
• Each output carries 20 mA max with residual voltage of 1.4 V for NPN.
• External input time adds 11 ms on top of connected expansion units.
• The design keeps response predictable across all eight channels.
• Separate outputs let you isolate faults without stopping the whole line.

Electrical and Power Data

• Supply voltage ranges from 10 to 30 VDC with 10% ripple P-P or less.
• The unit requires a Class 2 or LPS power source.
• Power consumption stays at 690 mW or less when the unit runs alone.
• At 24 V, current draw sits at 26 mA, excluding load.
• Low draw helps you share one supply across several units.

Environmental Durability

• Operating temperature spans -20 to +55 °C with no freezing.
• The housing resists vibration common on production equipment.
• The unit works reliably in tight cabinets and machine frames.
• Indicator LEDs stay visible for quick status checks.
• Approximate weight is 110 g, so mounting panels face little stress.

Installation Guide

• Mount the FS-MC8N on a DIN rail inside your control panel.
• Wire the 10–30 VDC supply to the correct terminals first.
• Connect each sensor to its separate output channel.
• Link expansion units in sequence and stay within the 1,200 mA limit.
• Check the STATUS LED for green before you start production.
• Confirm the MEMORY and LOCK LEDs show correct states after power-up.
