Electrical connections

SIPROCESS UV600, gas connections and electrical connections

The SIPROCESS UV600 is supplied as standard with one or (optionally) two input/output modules. The logic function of the signal connections can be configured individually with the service and maintenance software specific to SIPROCESS UV600.

The signal connections are available at terminal strips X3, X4, X5 and X7 on the 12-pin plug connectors of the input/output modules. The scope of delivery includes the corresponding counterparts (plug connectors) with screw terminals.

Pin assignments

SIPROCESS UV600, pin assignments of digital inputs X3 (DI1 to DI8) and digital outputs X4 (DO1 to DO4) and X5 (DO5 to DO8)

Characteristics of the digital inputs:

• Floating optocouplers with common reference potential (DIC)
• Switching range 14 ... 42 V DC (external control voltage)
• The digital inputs can be operated either with positive or negative voltage
• With inverted switching logic, the logic function of the control input is active if no current is flowing through the control input
• Maximum voltage: ± 50 V

Characteristics of the digital outputs:

• Floating relay changeover contacts
• Single-pole changeover switch, three connections
• Maximum voltage: ± 50 V
• Connect inductive loads (e.g. relays, solenoid valves ...) via spark-quenching diodes only
• Maximum load-carrying capacity (standard): Max. 30 V AC, max. 48 V DC, max. 500 mA.

SIPROCESS UV600, pin assignment of the analog inputs X7 (AI1 and AI2) and analog outputs X7 (AO1 to AO4)

Characteristics of the analog inputs:

• The input signal is an analog current signal (standard 0 ... 20 mA, maximum 30 mA)
• The signal current must be provided by an external current source
• Load (internal resistance) of analog input: 10 ?
• Reference potential GND (see figure, analog inputs)
• Overcurrent protection: ± 1 000 mA
• Max. voltage: ± 50 V

Characteristics of the analog outputs:

• Analog outputs are floating (electrically isolated) and provide a load-independent current signal
• Signal range 0 ... 24 mA
• Residual ripple 0.02 mA
• Resolution 0.1%
• Accuracy 0.25% of full-scale value
• Maximum load 500 ?
• Maximum voltage ± 50 V
• Adjustable start or error state

Note for electrical isolation:

The electrical isolation is canceled if the negative poles of the analog outputs are connected to GND.
