All about VLT 2800
Control card, analog output
Number of programmable analog outputs
Terminal number
Current range at analog output
Max. load to common at analog output
Accuracy on analog output
Resolution on analog output
The analog output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. See
chapter 5.1.1 Galvanic Isolation (PELV) for further information.
Control card, 24 V DC output
Terminal number
Maximum load
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 chapter 5.1.1 Galvanic Isolation (PELV) for further information.
Control card, 10 V DC output
Terminal number
Output voltage
Max. load
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. See
chapter 5.1.1 Galvanic Isolation (PELV) for further information.
Control card, RS-485 serial communication
Terminal number
Terminal number 67
Terminal number 70
Full galvanic isolation. See chapter 5.1.1 Galvanic Isolation (PELV) for further information.

Relay outputs
Number of programmable relay outputs
Terminal number, control card (resisitvie and inductive load)
Max. terminal load (AC1) on 1-3, 1-2, control card
Max. terminal load (DC1 (IEC 947)) on 1-3, 1-2, control card
Min. terminal load (AC/DC) on 1-3, 1-2, control card
1) The relay contact is separated from the rest of the circuit by strengthened isolation.
NOTICE
Rated values resistive load - cosΦ >0.8 for up to 300000 operations.
Inductive loads at cosΦ 0.25 approximately 50% load or 50% life time.
