Any of binary inputs I1...I4 may operate as counter input. This requires a change in the<br />
operating mode of input, which is made during its configuration. The counter can count<br />
„up” or „down”, and the range can be freely defined in range of 1 to 2 147 483 647.<br />
Counting "up" means that the counter value is increased by 1 for each detected pulse<br />
and after reaching the value set as "counter length-1" is reset to "0". Counting "down"<br />
diminishes the counter value by 1 for each detected pulse and after reaching the value<br />
set as "counter length-1" is reset to "0" to resume the value of defined maximum.<br />
Crossing the value of counter length sets counter flag for respective input.<br />
These flags may be used in events table to trigger rules.<br />
3.7.2. Relay outputs<br />
<strong>MT</strong>-<strong>021</strong> telemetry module has 4 relay outputs Q1 ... Q4. Outputs can operate in one of<br />
two functional modes:<br />
monostable<br />
bistable<br />
The outputs operate independently and are isolated from each other.<br />
Outputs are control by writing value to the internal register (No. 8 - OUT_CTRL flag).<br />
This can be made remotely via SMS or CLIP.<br />
3.7.3. Analog inputs<br />
<strong>MT</strong>-<strong>021</strong> provides two analog inputs marked as AN1, AN2 which can operate in<br />
following modes:<br />
AN1:<br />
PT100 sensor temperature readout<br />
voltage input - 0…5V/0…10V<br />
current input - 4…20mA<br />
