Digital Outputs
2 pulse / state digital outputs are available on the device. In option it is possible to have others pulse / state
digital outputs or simply others state digital outputs.
The technical features are:
-
Compliance with CEI EN62053-31 (Class A devices)
-
Maximum of digital output available: 8
-
Isolation level: 4KV
RMS
for 60 sec.
-
Output type: Photo-MOS (solid state); a
“non-closed Output”
is comparable to an open contact
-
Output voltage/current: 10÷300V

“Pulse”
output mode:

-
Pulse output period adjustable from 60ms to 1000ms
-
Pulse polarity programmable (active closed or active open)
-
Programmable pulse “weight”.
Output protections: varistor for transients;
current limiting to be provided externally.
The PhotoMOS have a behaviour identical to a mechanical contact which closes. Therefore, there are not problems with the
polarity.
Digital Inputs (option)
The EMS can be equipped with isolated Digital Inputs.
The Digital Inputs are available only with the relative option.
The technical feature are:
-
Number of Digital Input: 2 or 4 depending on the option version
-
Input Configuration: independent inputs (no common pins)
-
Isolation level 3.5KV
RMS
for 60 sec
-
Voltage Input Range: 24, 48, 115, 230Vac/dc (only one of the available options to choose in the order)
-
Nominal Input Current: max 5mA each @ all nominal voltages
-
Input Filter: Digital
-
Basic Operation Mode: pulse counter, status, change of time-band
-
T
ON_min
30ms; T
OFF_min
30ms;
The Voltage input must be defined before to order the instrument.
The AC/DC digital input are independent (no common pin) and can be wired without polarity care.
Analog outputs (option)
The instrument can be equipped with analog outputs. The options available allow to have 2 or 4 analog outputs matched or not
with 2 digital outputs. Each output can operate independently of others in voltage or current. The technical features are:
-
Isolation level: 3.5KV
RMS
for 60 sec
-
Lenght of connection: up to 1200m
-
Resolution: 12 bit (4096 values)
