Description
Parameters and specifications:
Function: SDSS-FEX-4A is mainly used for the output control of frequency converter, which can process analog signals, such as 0 ~ 10V/5V voltage signals or 0/4 ~ 20mA current signals.
Connection mode:
Impedance matching: Select the PLC output module according to the input impedance of the inverter to achieve impedance matching between the two.
Voltage range: When the voltage signal range of the inverter and PLC is different, appropriate measures need to be taken, such as series resistance for voltage division, to ensure that the two work within the normal voltage range.
Shielding measures: In order to prevent the weak current control signal from interference by external strong signals, it is recommended to use shielded cables or stranded cables.
Operating voltage and frequency: Although the specific voltage and frequency range is not explicitly given in the search results, ABB inverters can usually convert AC voltage into DC voltage, and convert DC voltage into AC voltage with adjustable frequency and voltage through inverter devices to meet the needs of motor speed regulation.
Functions:
Sdss-fex-4a is mainly used in the inverter system as an output module to adjust the speed of the motor or other related parameters according to the control signal of the inverter or PLC.
By combining with the frequency converter, SDCS-FEX-4A can realize the stepless speed regulation of the motor to meet the needs of various industrial automation applications.
