Engineered for ABB Bailey INFI 90 Serial Device Connectivity
This module connects serial devices to the INFI 90 control system. It provides reliable serial communication for the ABB Bailey INSPM01 unit. You will find this interface in systems with barcode scanners or weigh scales. Unlike basic converters, this version supports multiple protocols. It handles both RS232 and RS485 devices on two independent ports.

Functional Architecture and Port Configuration
This module connects to the INFI 90 backplane for data exchange. It uses two independently configurable serial ports for flexible wiring. You can set each port for different baud rates and data formats. Moreover, the module includes a dedicated microcontroller for protocol handling. This component manages all serial timing without host intervention. Consequently, the controller focuses on control loops rather than serial data management.
Installation and Operational Guidelines
The ABB Bailey INSPM01 consumes 100 mA at 24V DC during operation. It buffers up to 16 KB of data per communication port. You must set the DIP switches for the correct RS mode. Always use terminated cables for RS485 networks longer than 100 meters. This practice prevents signal reflections and data corruption. Furthermore, the module supports ASCII, Modbus RTU, and 3964R protocols. This feature matches various third-party serial device requirements.
Physical Characteristics and Environmental Limits
This serial module has a rugged, industrial-grade plastic housing. Its moderate 0.50 kg weight allows for easy rack installation. The layout follows ABB Bailey standard INFI 90 specifications. Therefore, it fits securely into any INFI 90 I/O rack. The module includes LED indicators for port activity and status. In addition, it maintains stable operation between 0°C and 60°C ambient temperature. You can store this unit safely between -25°C and 85°C.
