RDI-D-R, or Reverse Differential Inductive-Differential Relays, is a type of electrical relay that is commonly used in industrial control systems. It is typically used as a protection device in electrical circuits, such as those used in automated production process. It works by sensing the current in a circuit and will trip or open when a certain amount of current is sensed.The RDI-D-R is essentially two relays in one; a reverse differential relay and a differential relay. The reverse differential works as an over-current protection device, while the differential relay increases the sensitivity of the reverse differential relay, providing a tighter control over the current. Together, these two relays ensure that circuits do not become overloaded, preventing damage to electrical components and potential fire hazards.The RDI-D-R works on the principle of induction. A current is passed through a coil of wire and this induces a current in a second coil due to electromagnetic induction. This secondary current is used to monitor the current in a circuit and to detect any deviations from an expected value. If a predetermined level is exceeded, the RDI-D-R trips, thus cutting the power to the circuit. In the field of snap action, limit switches, RDI-D-R can provide an effective way to protect circuits against damage. For example, in automated production processes, which use large feeder belts and roller systems, it is important that the current passing through these systems not exceed a predetermined value as this could result in damage to the machine or even a fire hazard. By installing an RDI-D-R, this can easily be monitored and any excess current can be safely cut off. In the same way, RDI-D-R can be used to provide protection in other parts of a production process. For example, if the current in an electrical motor exceeds a safe level, the RDI-D-R can be used to trip the circuit and provide protection against overheating. Similarly, it can be used in combination with limit switches to provide protection against overloads and faulty equipment.RDI-D-R also has potential applications in other fields, such as in industrial process control or fault finding. By monitoring the current in a circuit, it is possible to detect variations in the expected load and detect any faults. This ability is useful in industrial process control, as it can be used to detect and respond to any issues before they cause damage or accidents.Overall, RDI-D-R is an important element of many industrial control systems. It provides an effective way to protect circuits and other electrical components and can also be used to detect faults and respond to any issues that arise. In the field of snap action, limit switches, RDI-D-Rs can be a valuable addition to an automated production line and can ensure that the system runs safely and efficiently.
