Control card, analog output:
Number of programmable analog outputs 1
Terminal number 42
Current range at analog output 0/4 - 20 mA
Max. load to common at analog output
500
Accuracy on analog output Max. error: 1.5 % of full scale
Resolution on analog output 10 bit
The analog output is galvonically isolated from the supply voltage (PELV) and other high-voltage terminals. See
section entitled Galvonic 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 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 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.
For CANopen/DeviceNet units, see VLT 2800 DeviceNet manual, MG.90.BX.YY.
Relay outputs:
1)
Number of programmable relay outputs 1
Terminal number, control card (resistive and inductive load) 1-3 (break), 1-2 (make)
Max. terminal load (AC1) on 1-3, 1-2, control card 250 V AC, 2 A, 500 VA
Max. terminal load (DC1 (IEC 947)) on 1-3, 1-2, control card 25 V DC, 2 A /50 V DC, 1A, 50W
Min. terminal load (AC/DC) 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.
Note: Rated values resistive load - cosphi >0.8 for up to 300,000 operations.
Inductive loads at cosphi 0.25 approximately 50% load or 50% life time.
