Configured for serial synchronous encoder data acquisition in POINT I/O systems, the Allen-Bradley 1734-SSI (1734-SSI SSI Module) provides direct physical/electrical execution through a single SSI communication channel.

Model Identification & Configuration

The 1734-SSI is a Serial Synchronous Interface module designed for Allen-Bradley POINT I/O architecture. The module provides one SSI communication port for connecting SSI-compatible absolute position devices and transferring synchronous serial data through the POINTBus network.

Hardware Specifications

EtherNet/IP and POINTBus Data Integration

The 1734-SSI operates as a POINT I/O communication module within distributed I/O systems. The module exchanges SSI device data through the POINTBus backplane while maintaining modular I/O expansion capability.

The Allen-Bradley POINT I/O platform uses deterministic industrial communication methods for controller integration. Module configuration parameters are stored through the controller software environment and depend on the selected network adapter and controller architecture.

Firmware and I/O Configuration Compatibility

The module configuration requires matching firmware compatibility between the POINT I/O adapter, controller system, and installed I/O modules. Firmware flash compatibility should be verified before replacing modules in an active control architecture.

The 1734-SSI supports I/O density scaling through POINT I/O modular installation, allowing additional modules to be added according to system architecture requirements.
