Connectors¶
1. Micro USB host¶
Warning
Max 250 mA
2. SD¶
Micro SD slot to expand storage
3. Contactor¶
Drive contactors and check stuck condition.
| Pin | Signal | Description |
| 1 | N | Neutral |
| 2 | N | Neutral |
| 3 | Ns | Neutral out sense (not used) |
| 4 | LAs1 | Line out sense A input 1 |
| 5 | CL2 | Contactor 2 Live terminal |
| 6 | CL1 | Contactor 1 Live terminal |
| 7 | LBs1 | Line out sense B input 1 |
| 8 | LAs2 | Line out sense A input 2 |
LAs1, LAs2 and LBs1 are connected to optocouplers to detect high voltages at the output of the contactor, to detect a welded contact.
Contactor coils can be driven by internal relays output. Connect the main one on pin 2 and 6, and the secondary one to pins 1 and 5.
