The WB-MCM8 inputs work on the principle of "dry contact" - shorting the input to ground ignd causes the input to work. | |||
There is an indication of the status of inputs from 1 to 8 and the status of the device on the front cover. | |||
When a pulse arrives at the WB-MCM8 input, the corresponding LED lights up, the value of the input state changes, and the value of the counter of operations of this input increases. The values of all operation counters are recorded in the non-volatile memory of the device. The number of counters is 32 bits. | |||
For each input, the debounce time parameter can be changed. Starting with firmware version 1.2.0, it is possible to measure the pulse frequency at the input. The maximum measured frequency is achieved when the debounce time parameter is set to 0 and depends on the revision of the device - from ~1.2 to ~3.2 kHz. | |||
