The ETS-2260 is a cybersecurity module providing 6 digital input channels (Wet/Dry contact) and 6 electromagnetic relay output channels (Form A). Each input channel can function as a 32-bit counter, while each output channel supports configurable Power-on Value and Safe Value settings, allowing safe use in applications with hazardous voltages. A built-in 2-port Ethernet switch supports daisy-chain topology, enabling flexible device deployment, simplified installation, and reduced infrastructure costs.

To ensure stable operation in harsh industrial environments, the module features photo-isolation with 3000 V_rms transient overvoltage protection (no channel-to-channel isolation), as well as EMS protection (EFT/ESD/Surge) and 3000 V_DC I/O isolation, significantly enhancing the system's anti-interference capabilities. Moreover, the module supports I/O Pair-Connection functionality for DI-to-DO channel pairing with a remote module. Once configured, local DI data can be sent to a remote DO module in Push mode, or the local DO module can get remote DI data in Pull mode via Modbus TCP.
