FCT18-BcR Industrial Asymmetrical Flashing Relay

Starting in Closed State with Adjustable On/Off Timing

Model: FCT18-BcR Series | DIN Rail Mount

Product Overview

The FCT18-BcR is an advanced asymmetrical flashing relay engineered for industrial signaling and alert systems. Featuring a unique starting-on design, this relay begins in the closed state when the control signal is applied, then alternates between open and closed states based on preset timing intervals. With its high-precision timing (±0.1%), robust construction, and universal voltage input (12-240V AC/DC), it’s the ideal solution for demanding flashing applications.

Key Technical Advantages

Universal Voltage Input

Operates with 12-240V AC/DC, compatible with global industrial power standards.

Asymmetrical Flashing

Starts in closed state with fully adjustable on/off timing cycles for custom flashing patterns.

Ultra-Compact Design

Space-saving 18mm width (90×18×64mm) for high-density control panels.

Exceptional Timing Accuracy

Time setting accuracy ∆< ±0.1% ensures precise flashing intervals.

Independent Timing Control

Separate adjustment for on and off durations (0.1s to 100 days) for custom flashing patterns.

Industrial Robustness

Designed for -20°C to +60°C environments with EMI resistance.

High-Capacity Output

16A C/O contacts (1 or 2 sets) for driving industrial lighting loads.

Button Setting & Locking

Precision time setting via tactile buttons with locking protection to prevent accidental changes.

  • Immediate visual identification of machine status
  • Reduces equipment downtime

Emergency Beacon Systems

Controls emergency beacons and strobes with distinctive flash patterns during critical situations.

Key Benefits:

  • High-reliability operation during emergencies
  • Custom patterns for different emergency types
  • Compliance with safety regulations

Conveyor Status Indicators

Signals operational status, jams, or maintenance requirements on material handling systems.

Key Benefits:

  • Immediate visual identification of issues
  • Reduces production downtime
  • Simplifies troubleshooting

Maintenance Alert Systems

Activates flashing alerts when equipment requires maintenance or calibration.

Key Benefits:

  • Proactive maintenance scheduling
  • Reduces unexpected breakdowns
  • Extends equipment lifespan

Timing Sequence

fct18-bcr-function-diagram

Flashing Operation:

1
Control signal (S) applied – output (R) starts in closed state
2
After preset time (T) – output switches to open state
3
After preset time (T) – output switches to closed state
4
Cycle repeats until control signal is removed

Wiring Diagram

fct18-bcr-wiring-diagram

Connection Guide:

Standard DIN rail mounting with screw terminals for secure industrial connections:

  • A1/A2: Power supply terminals (12-240V AC/DC)
  • S: Control signal input
  • 11/12/14 & 21/22/24: Output contacts (C/O)
  • T1/T2: On/Off timing adjustment

Parameter Setting

Time Adjustment Protocol:

1
To set new parameters, press and hold the button until the LED starts flashing.
2
Adjust the on and off timing parameters to desired values.
3
Press and hold the button until the LED stops flashing to save settings.
4
For the new settings to take effect, power cycle the device.
