Technical/electrical characteristics of the inputs and outputs.
5.9.1
Digital inputs.
All digital inputs are galvanically isolated through opto-couplers. All the digital inputs have
the following characteristics:
5.9.2
Digital outputs.
All digital outputs are galvanically isolated through opto-couplers. All the digital outputs have
the following characteristics:
5.9.3
Analog outputs.
Use shielded cables connecting their meshes to the corresponding shield pin. All the analog
outputs have the following characteristics:
Characteristic.
Value.
Nominal voltage.
+24 V DC (b18 V DC and +30 V DC).
High threshold "1".
Over +18 V DC.
Low threshold "0".
Under +9 V DC.
Typical consumption of each input.
5 mA.
Maximum consumption of each input.
7 mA.
Characteristic.
Value.
Nominal voltage.
+24 V DC (b18 V DC and +30 V DC).
Output voltage.
2 V less than the supply voltage.
Maximum output current.
500 mA per output.
Minimum cycle on.
Pins LI/O1 LI/O2: 25 µs (optional).
Rest of pins: 75 µs.
For the PWM and synchronized switching, only pins LI/O1 or LI/O2 may be used. Depending on the
input receiving the PWM pulse and the cable, an external load resistor (at least 10% of rated current;
if 24 V, 470
/ 2 W) improves signal quality and noise immunity.
Characteristic.
Value.
Command voltage within range.
±10 V.
Resolution.
16 bits.
Minimum impedance of the connected device.
10 k
.
Maximum cable length (unshielded).
75 mm.
