I.Product Positioning and Core Functions
1.Target Application Scenarios
Contactor Expansion:
Combined with ABB AF and A series contactors,it increases the number of auxiliary contacts(e.g.,from two to four or six groups)to meet the needs of complex control circuits.
It is suitable for scenarios such as motor start/stop control and inverter start/stop signal transmission.
Circuit Breaker Status Feedback:
Installed on the side of ABB Tmax XT and Emax 2 series circuit breakers,it provides open/close status signals for real-time monitoring in PLC and SCADA systems.
Relay Signal Conversion:
Converts the main circuit on/off status into low-voltage/low-current signals to drive loads such as indicator lights,alarms,and intermediate relays.
2.Core Functions
Contact Expansion:
Provides one to four independent contact groups(depending on the model).Each group consists of one normally open(NO)and one normally closed(NC)contact,supporting parallel or series operation.Signal Isolation:
The contacts are electrically isolated from the main circuit,preventing high-voltage interference from affecting the control circuit and ensuring signal stability.
