Description

TeSys Deca low signal interface module, for control of contactors LC.D09-D115 (3P). Static relay interface controlled by a 24V DC input signal. To be used with contactors with 24-250V AC coils (B7 to U7), for contactors LC.D80-D115 the use is limited to 100-250V AC coils (F7 to U7). To be mounted on a coil wiring adapter LAD4BB for contactors LC.D09-D38, LAD4BB3 for contactors LC.D40A-D80A, and directly on contactors LC.D80-D115.
