Max. load .................................................................................................................................................. 130 mA
The 24 VDC supply is galvanically isolated from the supply voltage (PELV) , but has the same potential as
the analog 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 galvonically isolated from the supply voltage (PELV) and other high-
voltage terminals. See section entitled Galvonic 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.
For DeviceNet units, see VLT 2800 DeviceNet manual, MG.90.BX.YY.
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:
