Signal relays are a type of electromechanical switch that are actuated by an electrical signal. They are often used to initiate actions or activate machines in response to a current or voltage signal applied to one or more inputs. The D3221 signal relay is designed for use in a wide range of electronic applications. It can be used to switch low-level DC or AC signals.
Overview
The D3221 is rated for currents up to 2 amps, and it has two SPDT outputs. It operates on an environmental temperature range of -30° to +125°C, and it has a total contact resistance of 1000 milliohms. It has a dielectric strength of 100mV, a pick-up voltage of 75mV, and a drop-out voltage of 35mV.
Working Principle
The D3221 relies on a proven design that takes advantage of the inherently low resistance of a low-level signal in order to pass it through to the outputs. When a current or voltage signal is applied to the inputs, it is picked up by the contacts, which then close the internal electrical circuit. This closes the switch, which in turn triggers the output contacts, allowing the signal to be sent on to the downstream circuits.
Applications
The D3221 signal relay can be used in a variety of applications where low-level signal switching is needed. It is ideal for use in switching audio or video signals, digital signals, and other circuit-level signals. It can also be used as a switch to activate motors or other mechanical devices, and can be used as an interlock circuit to activate or deactivate multiple devices in sequence.
The D3221 signal relay is suitable for use in a variety of environments, including in medical equipment, automotive applications, and consumer electronics. In addition, it is RoHS compliant, which makes it an excellent choice for use in industrial or commercial applications.
Conclusion
The D3221 signal relay is an excellent choice for any application where low-level signal switching is needed. It provides reliable operation, low contact resistance, and a wide operating temperature range. It is also RoHS compliant, making it an excellent choice for a variety of industrial and commercial applications.
