VLT ® 2900 Series 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 Ω Accuracy on analog output Max. error: 1.5 % of full scale Resolution on analog output 10 bit The analog output is galvanically isolated from the supply voltage and other high-voltage terminals. 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, but has the same potential as the analogue and digital inputs and outputs. 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 and other high-voltage terminals. 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. 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 (resisitvie 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. 80 MG.29.A3.02 - VLT ® is a registered Danfoss trademark
