Resolution on analog output .......................................................................................................................... 10 bit
The analog output is galvanically isolated from the supply voltage (PELV) and other high-
voltage terminals. See section entitled Galvanic Isolation.
Control card, 24 V DC output:
Terminal number ................................................................................................................................................. 12
Max. load .................................................................................................................................................. 130 mA
The 24 V DC supply is galvanically isolated from the supply voltage (PELV) , but has the same potential as
the analogue and digital inputs and outputs. See section entitled Galvanic Isolation.
Control card, 10 V DC output:
Terminal number ................................................................................................................................................. 50
Output voltage .................................................................................................................................. 10.5 V ±0.5 V
Max. load .................................................................................................................................................... 15 mA
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-
voltage terminals. See section entitled Galvanic Isolation.
Control card, RS 485 serial communication:
Terminal number ......................................................................................................... 68 (TX+, RX+), 69 (TX-, RX-)
Terminal number 67 ....................................................................................................................................... + 5 V
Terminal number 70 ..................................................................................... Common for terminals 67, 68 and 69
Full galvanic isolation. See section entitled Galvanic Isolation.
Relay outputs:
Number of programmable relay outputs ................................................................................................................ 1
Terminal number, control card ............................................................................................. 1-3 (break), 1-2 (make)
Max. terminal load (AC) on 1-3, 1-2, control card ........................................................................... 240 V AC, 2 A
Min. terminal load on 1-3, 1-2, control card ...................................................... 24 V DC 10 mA, 24 V AC 100 mA
The relay contact is separated from the rest of the circuit by strengthened isolation.
See section entitled Galvanic Isolation.
Cable lengths and cross sections:
Max. motor cable length, screened/armoured cable ...................................................................................... 40 m
Max. motor cable length, unscreened/unarmoured cable .............................................................................. 75 m
Max. motor cable length, screened/armoured cable and motor coil .............................................................. 100 m
Max. motor cable length, unscreened/unarmoured cable and motor coil ..................................................... 200 m
Max. motor cable length, screened/armoured cable and RFI/1B filter ............................................... 200 V, 100 m
Max. motor cable length, screened/armoured cable and RFI/1B filter ................................................. 400 V, 25 m
Max. motor cable length, screened/armoured cable and RFI 1B/LC filter ............................................ 400 V, 25 m
Max. cross section to motor, see next section.
Max. cross section to control wires, rigid wire .................................................... 1.5 mm
Max. cross section to control cables, flexible cable ....................................................................... 1 mm
Max. cross section to control cables, cable with enclosed core .................................................. 0.5 mm
When complying with EN 55011 1A and EN 55011 1B the motor cable must in certain
instances be reduced. See EMC emission.
