The Allen-Bradley 1203-GK2 serial communications module is a Series B SCANport interface designed for flexible connectivity with compatible industrial drives. Operating on either 24 Volts DC or 120–240 Volts AC, this module may potentially be applicable to both open and enclosed configurations depending on system design requirements. The 1203-GK2 is suitable for integration with SCANport-compatible Allen-Bradley drives such as the 1394 and 1305 series, providing reliable data communication across diverse automation architectures. It may possibly be used in industrial control environments throughout North America and Europe where robust communication modules are expected to enhance interoperability and network efficiency in distributed drive systems.
