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 galvanica lly isolated from the supply voltage (PELV) and other high-
voltage terminals. See section entitled Galvanic Isolation.
Control card, 24 V DC output:
Terminal number ................................................................................................................................................ 12
Max. load supplied from mains / 24 V external ................................................................................... 240/65 mA
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 section entitled G alvanic 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 D C 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.
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.
See section entitled Galvanic 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.
External 24 Volt DC supply:
Terminal nos ................................................................................................................................................ 35, 36
Voltage range ................................................................................................ 21-28 V (max. 37 V DC for 10 sec.)
Max. voltage ripple ..................................................................................................................................... 2 V DC
Power consumption with/without mains supply ................................................................................. <1W/5-12W
Reliable galvanic isolation: Full galvanic iso la tion if the external 24 V DC supply is also of the PELV type.
Sensor supply (T63, T73):
Terminal nos ............................................................................................................................ 201, 202, 203, 204
