Li-ion Tamer LT-ACC-HUB-POE-HON Gen 3 PoE Hub

The Li-ion Tamer LT-ACC-HUB-POE-HON is the PoE hub for the Li-ion Tamer GEN 3 lithium-ion battery off-gas detection system, which detects the venting of battery electrolyte solvent vapours that occurs early in a lithium-ion cell failure so that mitigation can take place before thermal runaway.

The hub originates the daisy-chain of sensors, distributing power and CANbus communications to them, and is itself powered over Ethernet from a Li-ion Tamer PoE Ethernet switch. It is intended mainly for larger systems, or where it would be difficult to provide 12 VDC power at each hub.

Key features

• Accepts up to 12 sensors (monitoring or reference sensors), split in any way between the Chain A and Chain B ports
• Powered via PoE from a Li-ion Tamer PoE Ethernet switch (LT-ACC-POE-4 or LT-ACC-POE-24), so no local power supply is needed at the hub
• Output port connects to the PoE Ethernet switch, which carries both data and power
• Multi-colour status LED shows normal operation, gas detected on the chain, missing terminator and communication errors
• Push button: press once to display sensor positions on the sensor LEDs, press three times to reconnect the sensors
• Mounting holes spaced to standard rack unit spacing; optional DIN-rail kit LT-ACC-HUB-MKT
• Only one hub type should be used per controller: do not mix LT-ACC-HUB-PWR-HON and LT-ACC-HUB-POE-HON on the same controller
