Technical/electrical characteristics of the inputs and outputs.
6.7.1
Digital inputs.
All digital inputs are galvanically isolated up to 500 V through opto-couplers. All digital inputs
meet the standard IEC61131-2 type 1 and type 3.
6.7.2
Digital outputs.
All digital outputs are galvanically isolated up to 500 V through opto-couplers. All the digital
outputs have the following characteristics:
6.7.3
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).
Activation level.
From +11 V DC on and between 2.1 mA and
2.6 mA.
Deactivation level.
Under +10 V DC or 1.5 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 LO1 LO2: 25 µs.
Rest of pins: 75 µs.
For the PWM and synchronized switching, only pins LO1 or LO2 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.
