Digital Logic Unit - Microcontroller Based Digital Control System | User-friendly Interface, Manual And Auto Modes, Fault Analysis With Safety Interlocks

we are engaged in manufacturing and supplying of Digital Logic Unit in Bengaluru, Karnataka, India. The microcontroller based Digital Logic Unit (DLU) controls and monitors the system features and safety interlocks of the DSA series Power Amplifier. The logic unit acts as a user friendly interface between the user and the equipment and can be operated both in manual and auto modes.

System parameters and trip interlocks are displayed on the alphanumeric display of the feather touch membrane keyboard front panel. Soft start and controlled shut down is offered with an online key on the front panel.

Shaker and amplifier safety interlocks are monitored and indicated on the front panel through a microcontroller chip. Interlock signals are routed through isolators and buffer network for proper latching and to prevent false triggering.

The signals are latched on to the fault analysis section of the microcontroller. Only after all faults are resolved, the system is allowed to go Online and increase the gain. Major system interlocks associated with DSA series of amplifier are over current, field fail, displacement limit, cooling shaker, over temperature, etc.
