Terminal nos. ground 20, 39
Reliable galvanic isolation: The 24 V DC supply is galvanically isolated from the supply voltage (PELV)*, but has the
same potential as the analog outputs.
* VLT 5001-5062, 525-600 V do not meet PELV.
Control card, RS 485 serial communication:
Terminal nos. 68 (TX+, RX+), 69 (TX-, RX-)
Reliable galvanic isolation: Full galvanic isolation.
Relay outputs:
1)
No. of programmable relay outputs 2
Terminal nos., control card (resistive load only) 4-5 (make)
Max. terminal load (AC1) on 4-5, control card 50 V AC, 1 A, 50 VA
Max. terminal load (DC1 (IEC 947)) on 4-5, control card 25 V DC, 2 A / 50 V DC, 1 A, 50 W
Max. terminal load (DC1) on 4-5, control card for UL/cUL applications 30 V AC, 1 A / 42.5 V DC, 1A
Terminal nos., power card (resistive and inductive load) 1-3 (break), 1-2 (make)
Max. terminal load (AC1) on 1-3, 1-2, power card 250 V AC, 2 A, 500 VA
Max. terminal load (DC1 (IEC 947)) on 1-3, 1-2, power card 25 V DC, 2 A / 50 V DC, 1A, 50 W
Min. terminal load (AC/DC) on 1-3, 1-2, power card 24 V DC, 10 mA / 24 V AC, 100 mA
1) Rated values for up to 300,000 operations.
At inductive loads, the number of operations are reduced by 50%, alternatively the current can be reduced by
50%, thus the 300,000 operations are maintained.
Brake resistor terminals (only SB, EB, DE and PB units):
Terminal nos. 81, 82
External 24 Volt DC supply:
Terminal nos. 35, 36
Voltage range 24 V DC ±15% (max. 37 V DC for 10 sec.)
Max. voltage ripple 2 V DC
Power consumption 15 W - 50 W (50 W for start-up, 20 msec.)
Min. pre-fuse 6 Amp
Reliable galvanic isolation: Full galvanic isolation if the external 24 V DC supply is also of the PELV type.
