After the collaborative robots from UR and new electric linear axes were added to the system world of the test stand at the end of last year, the company is now launching the next module offensive at Control 2018: new low-voltage sources, new proportional pressure modules and additional multiturn individual drives are intended to expand the area of mechatronic function and load testing of components and assemblies.

Test more electrical appliances

With the addition of DC modules for low-voltage devices that can be regulated in volt and ampere steps, Inotec is completing its range of electrical supplies for the Smarttester. While the first Schuko sockets for currents up to 20 amps and voltages up to 280 volts AC were added to the range at the end of last year, the new connections now also cover the DC ranges of 12 volts, 24 volts and 48 volts. This means that the Smarttester can now be configured for testing mains voltage components (for household appliances or tools) as well as for test series with small devices (toothbrushes, razors) that are operated with up to ten amps of current via a mains adapter or battery.

The new supply module provides two voltage sources that can be regulated independently of each other. The test specimens are then switched via a smart tester and its software sensors can monitor - and document - all relevant operating states and parameters. The new extra-low voltage connections cover up to 800 watts of total power and have overload, short-circuit and temperature protection.

Modern proportional technology

Also new are pneumatic modules with proportional pressure technology. These are modern, controllable 5/2-way valves with a six-millimeter connection and switching LED for each connection. They are preselected and controlled via the software of the universal test bench. The Smarttester can now be used to implement test scenarios with pneumatic actuators whose pressure (force) can be changed within a control range of zero to ten bar. With a control accuracy of plus/minus one percent, the performance of actuating and positioning systems can be tested under practical conditions or complex long-term tests can be carried out with placement and assembly units.
