The Power Over Ethernet (PoE) access control panels below have the capability to supply up to 12Vdc@650mA for readers and auxiliary devices inclusively. This is achieved by way of their respective terminal blocks (TB).
A couple of examples of auxiliary devices include a DC door strike or a PIR motion detector.
DC Door Strike
Use the transient clamping shown below to protect the relay contacts and to reduce electromagnetic interference (EMI emissions). Always protect against accidental overloads by wiring in an inline fuse to the C (common) side of the relay as shown below.
