Product Overview
PELCO PA30-0065-00-A1 is an industrial automation communication module designed for distributed control systems(DCS)and industrial networks.It supports high-precision clock synchronization,multi-mode loopback testing and anti-interference communication.It is suitable for complex signal transmission scenarios in the fields of power,energy,intelligent manufacturing,etc.
Technical parameters
Clock interface and synchronization
Clock type:Supports line clocks(extracted from external lines)and local clocks(generated via 2.048 MHz crystal).
Clock accuracy:frequency error≤32 ppm.
Clock mode:
The line-side sending end uses the system-side clock,and the receiving end uses the line-recovery clock.
Supports PRBS(pseudo-random bit sequence)test code stream insertion for communication link diagnosis.
Debugging and testing functions
JTAG interface:standard debugging interface,supports chip-level debugging and parameter configuration.
Loopback mode:
Local loopback:Verify internal signal integrity of the module.
Remote loopback:Test the external link connection status.
Payload loopback:Check the accuracy of data transmission.
Anti-interference design
Shielding and grounding:Adopt an isolation design to prevent induced current interference caused by the shielding layer closing loop.
Ground circulation suppression:Optimize the grounding strategy to avoid ground potential difference affecting the accuracy of logic circuits and analog signal.
Core functional features
High reliability communication
Supports multi-slot PRBS test code stream insertion to ensure the stability and data integrity of the communication link.
Flexible parameter configuration and fault diagnosis are realized through the JTAG interface.
Industrial-grade environmental adaptability
Anti-electromagnetic interference:shielding design and isolation measures to adapt to strong electromagnetic interference scenarios in industrial environments.
Wide temperature operation:The specific temperature range is not clearly marked,but it complies with the general standards of industrial modules(usually-40°C to 70°C).
Modular extension
Compatible with mainstream DCS systems(such as ABB,Schneider,Siemens,etc.),it supports collaborative work with other industrial modules.
Typical application scenarios
Industrial automation
As a communication node in the DCS network,clock synchronization and data transmission between devices are realized.
