Decentral Solutions
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 galvonically isolated from the supply voltage (PELV) and other high-
voltage terminals. See section entitled Galvonic Isolation.
Control card, 24 V DC output:
Terminal number ................................................................................................................................................. 12
Max. load supplied from AC lines / 24 V external ................................................................................. 240/65 mA
The 24 V DC supply is galvonically isolated from the supply voltage (PELV) , but has the same potential as
the analog and digital inputs and outputs. See section entitled Galvonic 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 DC 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 Galvonic Isolation.
Relay outputs:
Number of programmable relay outputs ................................................................................................................ 1
Terminal number, control card ............................................................................................. 1-3 (break), 1-2 (make)
Max. terminal load (AC) on 1-3, 1-2, control card ........................................................................... 240 V AC, 2 A
Min. terminal load 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.
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 power supply ................................................................................. <1W/5-12W
Reliable galvanic isolation: Full galvanic isolation if the external 24 V DC supply is also of the PELV type.
Sensor supply (T63, T73):
Terminal nos ............................................................................................................................. 201, 202, 203, 204
