What are the functions of signal relay?
Signal relay is composed of two parts, including contact system and electromagnetic system. The electromagnetic system consists of a coil, a fixed core, a yoke iron and a movable armature. The contact system consists of moving contacts and static contacts, which plays an important role whether it serves as the core component of relay signal system, or as the interface component of electronic or computer signal system. The functions of DPDT DC signal relay are as follows.
