United Automation Dual Mode Firing Circuit DMFC12 230VAC, TRIAC Thyristor, DIN Rail Mount, 11 Pin Count DMFC12 230VAC

United Automation DMFC12 230VAC dual mode firing circuit incorporates advanced TRIAC thyristor technology designed for industrial and electronic control applications. Featuring an 11-pin configuration and DIN rail mounting, this device supports both phase angle and burst fire control modes or a combination of both, allowing initial startup in phase angle mode followed by burst firing for optimal load control.

The module offers adjustable soft-start functionality with a duration range of 0 to 30 seconds, enabling smooth ramp-up of power to connected loads, thereby reducing mechanical and electrical stress. Its current limiting capability, implemented via an external current transformer or hall-effect sensor, enhances protective functionality safeguarding connected equipment.

The firing circuit accepts a wide variety of input control signals, including 0-5V, 0-10V, 0-20mA, 4-20mA, or potentiometer adjustments, providing versatile interface compatibility. Power supply options include 24V DC or an AC supply between 18 to 24 volts, enhancing installation flexibility in diverse environments.

Designed for precise load management, the output power span and zero adjustment features allow fine-tuning of the output power delivered to the load. Trigger pulses are synchronized strictly to the zero-crossing points of the mains supply, significantly reducing radio frequency interference when used with resistive loads.

Certified to IEC 950 and compliant with I.E.E. wiring regulations (BS7671), the DMFC12 assures safety and regulatory conformity. The device operates reliably within a temperature range of 0°C to 70°C, making it suitable for typical industrial conditions. Mounting on standard DIN rails simplifies integration into control panels and automation systems.

This dual mode firing circuit is ideal for industrial automation systems, HVAC controls, manufacturing equipment, and laboratory applications where accurate and flexible thyristor triggering is essential. The compact design facilitates space-saving installations while delivering robust performance.

Supports single phase or phase-to-phase trigger with phase angle and burst fire control modes. Adjustable soft-start time from 0 to 30 seconds for smooth power ramp-up. Current limiting via external CT or hall-effect sensor for protection.
