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