Description
The 781351-03 is a part of the Industrial Communication Interfaces category, specifically designed for the CompactRIO systems. This particular model, the cRIO-PB-S, is a CompactRIO Profibus DP Slave Module featuring a single port designated for Australia/New Zealand markets. Manufactured by National Instruments, it ensures high compatibility and performance.
This module stands out with its integrated flash memory for PROFIBUS DP Master Configuration Storage, providing reliable data retention. It supports a wide range of network baud rates, automatically detecting speeds up to 12000 kbits/s, and can handle input/output data sizes up to 240 Bytes each. Furthermore, the module is compatible with both CompactRIO reconfigurable chassis and NI Single-Board RIO devices, enhancing its versatility in application.
For communication, the module utilizes a 9-pin D-SUB port with an isolated RS485 interface, ensuring robust and secure data transmission. The process image data size can reach up to 8 kbytes, accommodating substantial data exchange requirements. Notably, the module is designed to support data rates ranging from 9600 bit/s to 12000 kbits/s, catering to a variety of industrial communication needs.
Ensuring safety and durability, the module features a 500 VDC isolation voltage, protecting both the device and its users from potential electrical hazards. Power efficiency is also a key aspect of its design, with a power consumption of only 2.5 W for both transmitting and receiving modes, making it an energy-efficient choice for industrial applications.
