5464-213 WOODWARD NETCON SIO

The Woodward 5464-213 is a NetCon Serial Input/Output Module (NetCon serial input/output module), used to connect the VME bus (VMEbus) or controller architecture with multiple serial communication ports.
✔ Acts as a serial port manager within the industrial control system
✔ Connects multiple RS-232/RS-485 devices
✔ Supports functions such as protocol conversion, data adjustment, and buffering
This module architecture is very common in large-scale control systems and is used to achieve physical and logical bridging between distributed I/O and the main control system.

5464-213 is a Netcon Serial Input/Output Module for turbine control systems in the WOODWARD 5400 series, connecting the VME bus to four serial communication ports.
The module manages four serial ports; ports A and B are RS-232 ports, and ports C and D support RS-232, RS-422, and RS-485 communication protocols.
The processor of the module is a 68030, which manages data transfer between the ports and the VME bus.
The module supports up to 4 KB of dual-port RAM and 64 KB of PROM.

Specifications:

Input voltage: 24 Vdc
Maximum operating current: 12 V
Operating temperature: -25°C to +70°C
Ports 1 and 2: RS-232, 110-38.4 Kbaud

                        Port A(J1)：RS-232  Low-speed point-to-point devices

                        Port B(J2)：RS-232  Backup/Redundant Serial Port

                        Port C(J3)：RS-232 / RS-422 / RS-485  More on-site equipment

                        Port D(J4)：RS-232 / RS-422 / RS-485  Complex on-site network

Common support network layer protocols include: Modbus RTU / ASCII & RS-232/RS-485 Industrial Standard Physical Layer
Power supply: 10 - 60 VDC

5464-213 can serve as a data exchange bridge between the control bus and heterogeneous serial devices, thereby bringing remote data back to the central controller/PLC, or distributing control instructions to the corresponding devices.

In a typical industrial control architecture:
√ 5464-213 as an I/O card or communication card
√ Conducts high-speed internal communication with the central control unit (such as MicroNet CPU) via VMEbus
√ The module only performs physical and logical serial port mapping and does not handle advanced logical judgments

From the perspective of communication functions, it can be combined with PLC or DCS systems through serial protocols:
✔ Connect RS-485/RS-232 terminal devices
✔ Bridge peripheral devices via protocols such as Modbus
✔ Can serve as a field I/O communication node for PLCs
