Equipped with 8 digital input points and adopting 24VDC power supply (with a voltage tolerance of -15% ~ +20%), it supports both sink and source input types to meet the connection needs of different industrial sensors and switches. It boasts excellent stability—even if the power supply is momentarily interrupted for up to 5ms, the device can continue to operate normally, effectively avoiding data loss or control interruptions caused by transient power failures. With an insulation resistance of over 5 megohms and strong noise immunity (8kV air discharge ESD protection and 2kV power line EFT protection), it can maintain stable operation in complex factory electrical environments.
