Resolution of switching event |
Distinguishing capability for bit changing in succession of multiple contacts. When the bit changing interval of any two contacts is more than 1ms, the distinguishing capability(less than 2ms) of the unit is reflected in SOE. |
| Remote communication scanning speed | Scanning cycle for all channels:1ms |
| Debouncing time of remote communication | Debouncing time is 1ms(adjustable) for all channels. |
| SOE capacity | 1600sets |
