SM-C series safety relay

·Universal shell: 22.5mm universal shell, with strong versatility in appearance and size.

·Three-proof paint coating on the circuit board: protect the circuit board from moisture, insulation, water and dust, and prevent parts from loosening to meet G3 anti-corrosion standards.

·Convenient wiring: the power supply is represented by red and black, the input terminal is represented by S plus number, and the input terminal is represented by number.

·All-localization: All-localization devices are adopted, with high cost performance and worry-free quality.

·Support a variety of equipment input: emergency stop button, safety door, PNP safety light curtain, expansion module.
