Carrier Wave Repeater
Detailed Product Description
Carrier Wave Repeater
Brief Introduction
Carrier wave repeater is used to extend the carrier wave communications distance,suitable for the recording system whose carrier wave centralizing machine is far away from the carrier wave meter. 1 to 4 sets of the carrier wave repeaters can be installed in the wire to extend the carrier wave communication distance.
This series product conforms to GB/T 698-1999 standard.
Function and Features:
(1). Characteristic of single-rate or multi-rate;
(2) Easy installation and use: It can work once it is connected to the A,B,C phase lines of the low-voltage grid (AC 220/380V). Among them, the C phase and zero line can supply the power for the repeater electronic wire.
(3) Carrier wave communication parameter: spread spectrum series 15 digits, central frequency 120K, bandwidth 15KHz;
(4)Agreement indication function: When the multi-rate repeater is powered, the B, C two phases communication indication light and A phases indication light (labeled D109) flicker 3 times.
When the single-rate repeater is powered, the B, C two phases communication indication light and A phases indication light (labeled D109) flicker once.
(5) Communication indication function:When the repeater receive the data, the B, C two phases communication indication light flicker once. When sending the data, A, B, C phases communication indication light flicker once.
