4 RELAY DIGITAL OUTPUTS OPTION 4DO (“PLUG IN”)
The option has 4 relay digital outputs. The instrument will manage 2 digital inputs and 6 digital outputs
(2 static and 4 relays). The pin-out is the same of the option before.
8.3.5)
2 ANALOG OUTPUTS OPTION 2AO (“PLUG IN”)
This option will allow to manage 2 digital inputs, 2 digital outputs and 2 analog outputs. See the
chapter 11.10) to program (0-20mA or 4-20mA) these outputs. The following table shows the pin-out:

Output is at galvanic insulation with maximum load impedance of 150
Ω
. The connection to other
peripherals as recorders, ammeters, remote indicators etc., must be carried out using a maximum
cable size of 2.5mm

.
If long distances must be covered, the wires connected to the EMA11 needs to be wired in a separate
channel from the power supply cables, if an intersection occurs between the power supply cable and
the analog wires, please remember to cross the intersection at 90 degrees, in order to cut the
generated magnetic fields.
