FAQ
AMB300 modules are powered by the AMB310 collector via the two-bus line, no separate power supply needed.
AMB310 has 2 downstream two-bus ports, each supporting up to 80 modules, total up to 160 modules.
AMB300-Z monitors 1 large-area array temperature; AMB300-D4/15 monitors 4 single points (15mm spacing); AMB300-D1 monitors 1 single point. Models with -H or -TH suffix support humidity monitoring.
Accuracy is ±3℃ in the range -10…85℃, and ±5℃ in the range 85…150℃.
AMB310 supports auto-addressing and manual addressing. Enter the auto-addressing interface via buttons, set the starting address, and addresses are automatically assigned; or manually assign addresses to individual modules.
Maximum line length per port is 250m. It is recommended to use CAT6a or higher oxygen-free copper Ethernet cable or 1.5mm² copper wire (for ant clip wiring).
Summary
The AMB300 solution offers non-contact temperature monitoring, eliminating physical contact with live busbars. The AMB310 collector supports up to 160 modules via two-bus, reducing wiring complexity. Array and single-point options cover different monitoring needs. With ±3℃ accuracy in the critical -10…85℃ range and optional humidity sensing, it provides comprehensive insight into connector health while simplifying deployment and maintenance.
