United Automation FC11AL, Thyristor Trigger Module

Phase angle trigger module for resistive & inductive loads. The MONO-LINK firing system is ideal for use with inductive loads via triac or thyristor on single phase-to-neutral, phase-to-phase supplies.

Remote power transformer for increased reliability and wide operational voltage capacity
MONO-LINK® gate-to-gate firing
High isolation opto-coupled output
Voltage control or 4-20mA current loop
Adjustable soft-start function
Auxiliary 5Vdc output for manual control
Status indication

Power transformer NOT included

The number of complete mains cycles during fixed repeating periods (typically 1 to 10 seconds) is varied, thus altering the duty cycle or on-/off-time ratio. Trigger pulses coincide with the zero-crossing times of the mains supply thus ensuring no RFI is produced when using resistive loads.
