70-IDC15

70-IDC15 application field and working principle are key concepts to understand when considering I/O Relay Modules. An I/O Relay Module is a type of device that is typically part of a electronic system, which is designed to operate and control a number of physical outputs from a single control input. 70-IDC15 refers to a 15 slot input/output relay module, so is designed to have 15 actuation points.The field of application for the 70-IDC15 Relay Module has multiple uses and can be employed in a range of electrical applications. It is primarily designed to be used in applications such as motor controllers, control systems, timers and control and protection circuits. Additionally, the 70-IDC15 Relay Module can be used in environments where situations of a large number of input signals need to be monitored, such as in door alarm systems or factory control systems.In terms of the working principle of the relay module, it has a protective function as well as a control function. The module is connected to a power source. An input signal is applied to coil terminals of the relay. The coil will then be energised, thereby increasing the current. This causes a magnetic field to be generated and the contacts to move, thus activating the relay and allowing it to switch a circuit.The 70-IDC15 Relay Module is available from various electronic competitors as either pre-assembled units ready for connection, or as component parts ready for assembly. It is commonplace design for the relay module to hold up to 15 groups of output contacts and includes a self-locking feature, which is not able to be de-energised until the input signal is re-applied. The contacts are separated by a sealing diode, to prevent any backflow of current.To increase the longevity and improve the protection capabilities of the 70-IDC15 Relay Module, a semiconductor device is emplaced on the control board of the relay. This serves to protect the contacts against electrical wear due to the load current being too great or any interference due to electromagnetic fields.Additionally, a current problem with the 70-IDC15 Relay Module is that it may be too slow to operate, due to the time taken for the contacts to move and for the magnetic field to be generated. To speed this process up, a quantity of associated components are used to increase the speed of the response. These components typically include contactors and other resistive components, which increase the speed of the switching.The 70-IDC15 Relay Module can also be integrated into other electronic systems, such as those used for controlling the output of audio or video signals from a device. In this case, the relay module would enable signals to pass through the circuit when the contacts are closed and stop the signals when the contacts are open.Finally, because the 70-IDC15 Relay Module operates with a controlled physical output, the resulting electrical signals can be used for a range of applications, such as switching lights, generating alarms, or controlling industrial machinery. The wide range of applications mean that the 70-IDC15 Relay Module is a versatile component in the field of electrical systems and is a very useful addition to any home, industrial or commercial electrical system.
