Mains Unit, SK TU4-24V-…
The Mains Unit is used for the production of the 24V control voltage for the FI from the available mains
voltage (115V/ 230V/380V/500V). With this, a separate external 24V control voltage is not necessary.
An analog output is also available for the connection of a potentiometer.
• Mains unit for 100-240V, SK TU4-24V-123-B
• Mains unit for 380-500V, SK TU4-24V-140-B
• +24V- output voltage
• 1x analog input (e.g. potentiometer)
• 1x impulse output
• Status LED = 24V
• Max. permissible continuous current: 420mA
The Mains unit SK TU4-24V-…can only be used in combination with an SK TI4-TU-NET adapter unit.
Details of the control connection are described in the Section for the Adapter Unit (Section 3.5.1.2)
A connection and parameterisation example is described in Section 3.4.1.
To process current setpoint values (0(4)-20mA), the enclosed bag contains a 500
Ω
resistor, for connection
between terminals 11 and 14. Matching of the relevant input of the frequency inverter is made via parameter
(P420).
Setpoint Parameter [Array] Setting
0 … 20mA P420 [-02] or [-03] {26}
4 … 20mA P420 [-02] or [-03] {27}
