ASAP Semiconductor LLC
Relays a variety of applications depending upon their design and configuration. When controlling high current loads, the electrical relay only requires a small amount of current to pass through the coil, allowing for the contacts to activate the larger load similarly to an actuator or switch. Electrical relays may also drive multiple outputs with a single input, managing several independent circuits. Lastly, relays also may be used to transmit varying forms of electrical signals, such as controlling an AC... (read more) -

Codesys Group
Logic and motion control in one IEC 61131-3 system In addition to PLC logic, many machines also require motion control. Until now, both "disciplines" have usually been handled separately, each configured with its own software and executed on different hardware. The computing power of current control architectures enables logic and motion control to be executed on a single device. In addition to reduced hardware costs, you also benefit from more efficient engineering: By integrating CODESYS Motion CNC Robotics into the CODESYS Development System...
