Information About 172JNN21032
The 172JNN21032 is a Momentum expansion component installed between a compatible processor adapter and input/output base. Its Lexan housing incorporates a communication indicator and an accessible battery compartment. Operating power comes from the base through the assembled module connections. Serial-port availability depends on the processor combination, because processors with a dedicated Modbus port 2 can disable the adapter’s communication port while retaining its clock and backup functions.
Key Features:
- Selectable Serial Interface: Configures one communication port for RS-232 or RS-485 operation through software.
- Modbus Connectivity: Provides a general-purpose asynchronous serial interface with slave functionality.
- Time-of-Day Clock: Supplies onboard timekeeping with a specified accuracy of ±13 seconds per day.
- Battery Backup: Uses a replaceable 2/3 AA lithium battery for backup functions.
- Communication Indication: Includes a green activity light for monitoring serial-port traffic.
- Base-Supplied Power: Receives its operating voltage through the Momentum input/output base.
- RS-232 Auto-Logout: Supports automatic logout after a programming-panel cable disconnection to help prevent port lockup.
The 172JNN21032 delivers the reliability and precision required for serial communication and timekeeping in compatible legacy Momentum control systems.
