ETL-2255 is a 8-channel DI (Wet/Dry Contact) and 8-channel DO (Sink-type) module. Each input channel can function as a 32-bit counter, while each output channel can be configured with a power-on value and safe value, ensuring the module’s safe operation in applications with hazardous voltages.

The module features a T1L design that supports transmission distances of up to 1000 m and includes a builtin 2-port Ethernet switch, facilitating a daisy-chain topology. This feature offers flexibility in device configuration, simplifies installation, and reduces infrastructure costs.

The module features optical-isolated 3000 Vrms transient overvoltage protection and does not support channel-to-channel isolation. Additionally, it provides EMS (EFT/ESD/Surge) protection and 3000 VDC I/O isolation to enhance noise protection capabilities in industrial environments.
