Description
The Controller is for use with most products in Control Engineering range, but it will work with any other compatible laboratory equipment. 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 experiment module. The blocks include: • Proportional and integral blocks • A complete three-term PID (proportional, integral, derivative) block • Fully adjustable potentiometers that can work as setpoints or attenuators • A function generator and digital voltmeter • Summing junctions • Phase lead The controller also includes an interface with D/A (digital to analogue) and A/D (analogue to digital) connections. This allows the user to connect their product from the CE range to a suitable computer (not supplied) for computer control and data acquisition. The controller includes a copy of Control Software (see separate datasheet for details). The Controller is a more advanced alternative to the Interface, as it has the additional analogue control features.
