Technical data
| Input circuit | 32 circles | ||
| Input mode | Active wet contact (DC 12 V) or passive dry contact | ||
| busbar | Half-duplex RS485 (Modbus RTU), three-wire shielded cable is recommended | ||
| Bus capacity | ≤32 | ||
| Switch event resolution | The ability to distinguish between consecutive displacements of multiple contacts. If the displacement interval between any two contacts is greater than 1 millisecond, the ability to distinguish units (less than 2 ms) is reflected in the SOE. | ||
| Remote scanning speed | The scan time of all channels for one week is 1 ms | ||
| Debounce time of the remote signal | All channels use a uniform debounce time of 1 ms (configurable). | ||
| Event Sequence Logging (SOE) capacity | 1600 groups |
