Technical Manual 1.02, C350 Professional
Digital I/O
The C350 pro unit has eight digital inputs and eight digital outputs. Digital input 1-5 has
several operation modes. Please refer to the digital input section for additional information.
The digital outputs are integrated high performance "high-side" switches.
Digital outputs
The digital outputs control eight "high-side" switches. They function like a contact, where
one side is connected to the positive supply of the C350 unit, and the other is the output.
The switches are protected against short circuit, ESD and electronic kickback from
inductive loads such as relays etc. The maximum switchable inductance is 20mH and
must not be exceeded.
The digital outputs are supplied directly from the SUPP power pins, which also supplies
the rest of the C350 unit. As the power is also the C350 pro main power, a power-fail
would also affect the digital outputs.
The C350 pro unit offers a very advanced power management, which makes it possible to
have one or more outputs enabled while the unit is in low power mode. Please consult the
M2M Control IDE on-line help for more information.
Please note: Special attention to wiring must be taken; if the total current consumption of
the digital outputs exceeds 1A then PGND must be used as return path for the output(s).
If the total current consumption of the digital outputs exceeds 5A two SUPP and PGND
pins must be used for supply.
