Technical parameters

Performance	Indicators
Input circuit	8/16/32
Input mode	Active wet contact (DC12V) or passive dry contact
Bus way	Half duplex RS485 (Modbus RTU), three-core shielding wire is recommended
Bus capacity	≤32
Switch event resolution	The ability to distinguish successive displacement of multiple contacts. When the displacement interval of any two contacts is greater than 1 millisecond, The ability to differentiate units (less than 2ms) is reflected in the SOE
Remote scanning speed	The scanning time of all channels for one week is 1ms
Remote signal debouncing time	All channels adopt a unified debuffing time of 1ms(configurable)
Event sequence logging (SOE) capacity	1600 groups
