The
Embedded Power Line Carrier Modem 101 is a circuit module which can
be integrated into and become part of the user's system. It is a
device for transferring data over the power cable at the low voltage
end of the power transformer of a 3-phase/ 4-wire distribution
network. A pair of the PLC Modem 101 connected on the same phase and
neutral line of the power network can provide bi-directional data
communication at a baud rate up to 1200 bps.
Schematics:
1. 1-Phase Type Principle
(PLC101-5,PLC101-12)
2. 3- Phase Type Principle
(PLC103-12)
Features:
¡ô A
circuit module built with SMT components.
¡ô
Single-phase and 3-phase types are available.
¡ô In
a multi-drop communication environment, a 3-phase modem can be
connected to several single-phase PLC modems.
¡ô
PLC Modem and users' existing devices (systems) connected to the
same Neutral Line.
¡ô Baud
Rate of PLC is 600/1200bps.
¡ô
Transparent to the communication protocol of user's devices
(systems).
¡ô Operates
at the low voltage end of a power transformer of a 3-phase/ 4-wire
distribution network.
¡ô
Designed to operate under industrial environment.
