POCSAG Data Transmitter - POCSAG Data Receiver - POCSAG Data Encoder - POCSAG Radio Paging Products

E800PE Data Encoder 8 Dry Contact Trigger Inputs.

The E800PE is a compact digital POCSAG encoder suitable for most paging and data sending requirements. With the wide operating voltage range, the encoder offers a flexible means of data interfacing and message sending capabilities. Each of the eight trigger inputs can be used to store eight individual messages or programming commands. When used with the

TXF-2000E Data Transmitter detailed below, long range message paging (up to 1KM) or signal control commands to a data receiver such as the Y1727RY2 featured below with dual relay outputs. Connector lead supplied.


TXF-2000E POCSAG Data Transmitter - Long Range Paging  Telemetry Transmitter.

The TXF-2000E is a high power 100mW FM band data link and paging transmitter ideal for integration into OEM projects. When used with the EP800E data encoder most data relaying and message paging can be achieved. The transmitter and encoder can be used for long range security application, emergency signalling, fire alarm conversion to incorporate radio paging and reliable long range switching applications using the Y1727RY2 data receiver with relay outputs.
