LINE POWERED RINGING INTERFACE UNIT

This Housed PCB board has the basics of the Ringing Interface to drive an input to a PLC, Crestron or Access Control input I/O unit etc. for signalling purposes via the LAN system. No external power required. It is recommended that the device that is being driven has an isolated input for the PCB. Isolation should be greater than 3kv.  If not available we recommend the use of the RD-RLY01 unit which has greater than 7kv isolation from the line and it is PTC approved.
