PLC200 – CAHN
Highest flexibility
and strongest performance in the field
CAN BUS HUB – POWER OVER CAN
The PLC200 system includes the CANH module, allows you to extend the CAN bus on four separate RJ45 connectors on each of which are expected the two CAN bus and power supply for external 24VDC (Power Over Can), such as Ringtone (BELL) and Emergency Panel (EMPA).. Each branch is galvanically isolated from the Bus at the back of the PLC. All branches are logically part of the same bus with the PLC base buses. Each branch is topologically a chain start, allowing otherwise impossible star connections. Each branch can be individually activated / deactivated via CANBUS. Local diagnostic indications: on each RJ45 port enabled (green LED), traffic on Bus (yellow LED, on the module, correct configuration (green LED) and abnormal operation (red LED)

Power over CAN (PoC) is a technology for wired CAN-bus local area networks that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. Doing so minimizes the number of wires that must be strung in order to install the network.
RJ45 plugs feature eight pins to which the wire strands of a cable interface electrically. Each plug has eight locations spaced about 1 mm apart into which individual wires are inserted using special cable crimping tools. The industry calls this type of connector 8P8C, shorthand for eight position, eight contact. Ethernet cables and 8P8C connectors must be crimped into the RJ45 wiring pattern to function properly. Technically, 8P8C can be used with other types of connections besides Ethernet; it is also used with RS-232 serial cables, for example. However, because RJ45 is the predominant usage of 8P8C, industry professionals often use the two terms interchangeably.
