Delta Tau’s Brick range of versatile and powerful stand alone controllers has been extended to include the new Geo Brick LV low voltage model for controlling all types of low voltage servo and stepping motors. The latest product completes a family of motion controls to suit all types of machinery and motion applications. Also released is the latest Brick Controller, a fully programmable motion controller based around a powerful Turbo PMAC platform.

The new Geo Brick LV provides control of up to eight disparate motor types and like its high voltage counterpart, the Geo Brick LV features an integrated high performance Turbo PMAC controller. It also includes up to eight configurable low voltage amplifiers capable of running any type of motor from DC servo, synchronous AC servo to stepper technology.

Readily programmable for virtually any kind of motion control application, the versatile PMAC2 controller offers advanced features which include S-curve acceleration and deceleration, cubic B-spline interpolation and optional multi-move look ahead for velocity and acceleration limiting. Amplifiers within the new low voltage Brick are rated at 5A continuous, with a 10A peak facility at 48V.

Among the options available are a MACRO interface that complements the USB and Ethernet interfaces which are fitted as standard. There are also facilities for adding analogue inputs and digital I/O that in many applications eliminates the need for a separate PLC to be used to provide standard machine control functions.

The new Brick controller is an open architecture controller utilising the intelligence and capability of its embedded Turbo PMAC having the ability to store programs locally, and its built-in PLC execution makes it suitable for virtually any kind of automation application. This tried and tested architecture allows for complete machine motion and logic control.

This product has 4 or 8 (optional) axes of analogue +/- 10V filtered-PWM (12-bit resolution) or pulse and direction outputs as standard. Options are available for dual true-DAC analogue outputs at 18-bit resolution or direct-PWM with current loop. Feedback with quadrature incremental encoders is standard. Options for sinusoidal, resolver or serial encoders are available.

The controller provides a standard I/O capability of 16 inputs and 8 outputs at 12-24V fully protected and isolated with separate commons for each bank of 8 inputs. Outputs are rated for 1A each and are thermal-fuse protected. Outputs can be current sinking or sourcing depending on use of common emitter or common collector connections. Additional I/O is an option (up to 64 inputs and 32 outputs). Also an option for up to four 16 bit analogue inputs is available.

The Brick Controller’s functionality doesn’t stop there with features such as extensible I/O via ModBus TCP master, or ModBus TCP slave for third party HMI hardware. Our PC-based HMI package connected through USB 2.0 or Ethernet makes the Brick Controller a powerful single source solution.
