Controller

• This compact unit has analogue electronic circuits connected in blocks. 
• These blocks mimic the important parts of industrial controllers. 
• Clear diagrams on the front panel of the controller show the blocks, each of which has its own set of connection sockets. 
• The user connects the blocks in any way that they need and then connects them to their chosen products in the range. The controller also includes an interface with D/A (digital to analogue) and A/D (analogue to digital) connections.

The blocks include:

• Summing junctions.
• Phase lead. 
• Proportional and integral blocks.
• A function generator and digital voltmeter.
• A complete three-term PID (proportional, integral, derivative) block.
• Fully adjustable potentiometers that can work as setpoints or attenuators.
