FCT18-BP Industrial Interval Relay
Precision Interval Timing for Industrial Automation
Product Overview
The FCT18-BP is a high-precision interval timing relay designed for industrial automation. Engineered to provide reliable interval timing without control signal functionality, it activates immediately upon power application and opens after a preset interval. With its compact 18mm DIN rail design and wide operating voltage range (12-240V AC/DC), the FCT18-BP is the ideal solution for applications requiring precise interval timing without complex triggering mechanisms.

Timing Sequence
Timing Operation:
When power is applied, the output (R) closes immediately.
The timing period T starts simultaneously with power application.
After the preset time (T), the output (R) opens.
The output remains open while power is present.
