Function description
5.1.2
Supply voltage
The PMCprimo C2 has two supply voltages:
}
X40a/1,3
Supply voltage for the device and the digital outputs (24 VDC)
}
X40a/2,4
Supply voltage for the encoder (5 V, 24 VDC)
The voltage is connected directly to the Mini-I/O connector X41/1,2.
Internally the two supply voltages are galvanically isolated. The two earths can be connec-
ted externally.
5.1.3
Digital inputs
The device has 8 digital inputs.
The inputs are compatible with EN 61131-2, Type 1.
The time behaviour of the digital inputs depends on the method of use:
}
With normal use, the inputs have a filter time of ≤ 600 μs.
}
If the inputs are used as reference inputs, the reaction time to 0/1 or 1/0 pulse edges is <
5μs.
The inputs can be used as reference inputs, to poll the position of the encoder for ex-
ample.
5.1.4
Digital outputs
The device has 8 single-pole digital outputs.
Signals at the output
}
"0" signal (0 V) at the output:
– Output is high impedance
– No current to the load
}
"1" signal (+24 V) at the output:
– Output is low impedance
– Current is supplied to the load
– The maximum current strength per output is 0.5 A.
All digital outputs are protected against short circuit and overload.
The outputs can be used to connect relays, valves or inputs from another controller, for ex-
ample.
