1403-NSC

The communication module, 1403-NSC, from Allen Bradley’s Powermonitor II series is an essential component designed to enhance communication capabilities. This device employs the Remote I/O protocol, facilitating reliable data transmission in automated systems through its two active ports. It accommodates both RS-232 and RS-485 serial protocols, providing versatility for various applications.

Data transfer speeds are adjustable, with a baud rate ranging from 1.2 kbps to a maximum of 230 kbps, catering to different operational requirements. For connection, it utilizes daisy chain topology, enabling straightforward linking with other devices in a network. The termination resistance is designed to be either 84 Ω or 150 Ω, ensuring optimal signal integrity during communication.

The module primarily interfaces with the 1403-MM Master Module, effectively enhancing its data exchange capabilities. Isolation of the ports can withstand 500 V, which helps protect against electrical surges and enhances overall safety. A twinax cable—specifically the 1770-CD—is required for Remote I/O connectivity. Furthermore, the installation process utilizes a plug-in card format, making it easy to integrate into existing systems.

To aid usability, the 1403-NSC includes LED indicators for TXD, RXD, and RIO to provide real-time feedback on communication status. This combination of features makes the module suitable for dual-port communications in various industrial automation setups.
