M4M 20 NETWORK ANALYZER USER MANUAL
45
Input
Slots 3 and 4 of the I/O menu for M4M 20 I/O contain programmable I/O that can be configured as follows:
I/O type I/O type
Pulse input Pulse output
Alarm output Output ON
Comm. output Output OFF
Selecting Pulse Input, the device counts detected pulses connected to input port, that should last at least
30ms. It is needed to consecutively set a pulse ratio associated to the pulse counter, and then a unit of
measurement to be associated to the pulses.
Setting page Description
1. Pulse ratio Manual value between 1 and 999999.
2. Unit
No unit, Wh, kWh, MWh, Varh, kVarh, MVarh, VAh, kVAh, MVAh, gal,
BTU, L, m^3, MCF, lbs, kg, klbs, Therm.
Analog output
Slots 5 and 6 of the I/O menu for M4M 20 I/O contain analog outputs that can be used to associate a
measured parameter to a current output value.
It is possible to define the parameter to be associated to the analogue output, as well as minimum and
maximum measured values to be linked to the output span.
Menu Description
Output span
0 - 20mA or 4 - 20mA.
