Interface relays Connecting links between logic and load Solid-state coupling relays Electronic control units have been inherent parts of advanced automation technology for a long time. Already in the early seventies, they superseded bit by bit contactor and relay control systems that were usual by then. With them, the power consumption of control systems working with extra-low voltage could be reduced to a minimum. However, the energy demand of the power level for driving motors, magnetic clutches or hydraulic cylinders has not changed up to now. They still need a high amount of electrical...

CANopen Requirements and application fields for fieldbus systems Control equipment in machines and installations becomes more and more complex. However, sensors and actuators are often conventionally wired. But with increasing complexity and performance also the time needed for engineering, installation, wiring, commissioning and maintenance increases. Such work becomes more confusing, error-prone and also more costly. An alternative is the use of bus systems. Some advantages of fieldbus systems are listed below: Advantages of fieldbus systems - Wiring becomes clearer when actuators and sensors...

CANopen DOLD offers devices for two-wire transmission that can be used in their basic function (plug & play) without programming tool. The following describes most simple easily implementable application examples. Attention: To achieve a transmission in plug & play mode it must be ensured that one input module, e.g. IP 5502, with the address set to 1 is connected to the CAN bus. Simple remote control Using DOLD’s input modules IP 5502 and output modules IP 5503 it is easily possible to transmit input signals to output relays over large distances via two-wire cables without programming (e.g....
