The Br-EFB is used when you need to close a servo loop to control analog pneumatic and hydraulic cylinders, DC motors, or stepper motors. These are used in animated shows, motion bases, industrial systems, special effects, fountains, and more.
An EFB card measures the position of a movement, compares this with the position it is being told to be at, and opens or closes the valve (or turns on of off the motor) to get the movement to where it should be. The Br-EFB does this thousands of time each second. The Br-EFB also supports ‘compliance’, which adds force feedback to the loop.
- Up to eight axis of PID Electronic Feedback. Up to four axis when using compliance, or two axis with differential compliance (plus two more EFB or one compliance axis)
- Resolution of eight or twelve bits for each axis being controlled. Sixteen bit resolution A/D for feedback
- Twelve bit resolution PWM outputs rated at five amps can run most servo valves and small motors
- Highly oversampled PIDD loop for outputs smooth enough to run even the largest motion bases
- Self adjusting initial setup, and automatic adjustment while running. Auto settings can be overridden
- Analog endpoints can be adjusted anywhere within the range of movement, and even reversed
- Accepts DMX-512 or serial RealTime data from a PC•MACs system during programming. Can be used as a part of a permanent PC•MACs system. Error checking prevents glitches from bad data.
- Operates as a ‘Smart’ Brick or ‘Dumb’ Brick. Use ‘Smart’ Brick Mode when you are using a ‘Smart’ Brick Brain as a time code reader to synchronize with an external source of time code (LaserDisc, DVD, Smpte, etc.).
- Use ’Dumb‘ Brick mode when you just need it to trigger and play a prerecorded show
- Four MByte of Flash memory for a capacity of over two hours at 30 FPS and sixteen channels. The flash is factory expandable to eight MBytes, or external storage can be used if needed.
- Once downloaded, show data is retained for approximately forty years, with or without power applied. A ?Write Protect? switch can protect show data from accidental changes. Up to 255 shows can be loaded onto a Br-EFB at one time.
- Two line x sixteen character LCD screen for status and configuration. You can ‘jog’ an axis or make minor adjustments using the encoder knob. LED indicator for Heartbeat, DMX-512 and Brick Net status, and errors.
- Networkable! In ‘Dumb’ Brick mode, four optoisolated inputs can be used to start, stop, pause, continue, or access shows. Can be controlled and Configured through the networked RS-422 port.
- Fits any ‘Brick’ card cage. These are available with from one to sixteen slots, rack mounted or not.
- Z-Brick output allows up to sixty-four Z-Bricks. Each Z-Brick adds thirty-two digital outputs.
- The Br-EFB runs on any voltage from nine to 24VDC
