FCT18-2T Industrial Power On Delay Time Relay
Dual Independent Timing Channels with Retrigger/Restart Functionality
Product Overview
The FCT18-2T is an advanced power on delay time relay featuring dual independent timing channels with retrigger/restart control functionality. Designed for complex industrial automation systems, it provides two separate timing controls in a single compact unit. Each output channel operates independently with its own timing sequence, offering unparalleled flexibility for sophisticated control applications. With its 18mm DIN rail design and wide operating voltage range (12-240V AC/DC), the FCT18-2T is the optimal solution for demanding applications requiring multiple independent timing sequences.

Dual Timing Sequence
Independent Timing Operation:
R1 Contacts
The timing period T1 starts on power-on. At the end of T1, R1 closes.
Closing of S opens R1.
Opening of S restarts T1. At the end of T1, R1 closes.
R2 Contacts
The timing period T2 starts on power-on. At the end of T2, R2 closes.
Closing of S opens R2.
Opening of S restarts T2. At the end of T2, R2 closes.
