Danfoss VLT CDS 303 User Manual

Analog Output
Number of programmable analog outputs 1
Terminal number 42
Current range at analog output 0/4 to 20 mA
Max. load to common at analog output 500 Ω
Accuracy on analog output Max. error: 0.5 % of full scale
Resolution on analog output 12 bit
The analog output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals
Control Card, 24 V DC Output
Terminal number 12, 13
Max. load 200 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.
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
Control Card, RS-485 Serial Communication
Terminal number 68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61 Common for terminals 68 and 69
The RS-485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from
the supplier voltage (PELV).
Control Card, USB Serial Communication
USB standard 1.1 (Full speed)
USB plug USB type B device plug
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. The USB
ground connection is not galvanically isolated from protection ground. Use only isolated laptop as PC connection to the
USB connector on the frequency converter drive
Relay Outputs
Programmable relay outputs 2
Relay 01 Terminal number 1-3 (break),1-2 (make)
Max. terminal load (AC-1)1) on 1-3 (NC), 1-2 (NO) (Resistive load) 240 V AC, 2 A
Max. terminal load (AC-15)1) (Inductive load @ cosφ 0.4) 240 V AC, 0.2 A
Max. terminal load (DC-1)1) on 1-2 (NO), 1-3 (NC) (Resistive load) 60 V DC, 1 A
Max. terminal load (DC-13)1) (Inductive load) 24 V DC, 0.1 A
Relay 02 (CDS 302 only) Terminal number 4-6 (break), 4-5 (make)
Max. terminal load (AC-1)1) on 4-5 (NO) (Resistive load) 400 V AC, 2 A
Max. terminal load (AC-15)1) on 4-5 (NO) (Inductive load @ cosφ 0.4) 240 V AC, 0.2 A
Max. terminal load (DC-1)1) on 4-5 (NO) (Resistive load) 80 V DC, 2 A
