YOKOGAWA SNT501-53 Optical ESB Bus Repeater Slave Module

Description

YOKOGAWA SNT501-53 Optical ESB Bus Repeater Slave Module is an industrial optical bus repeater module designed for use in industrial control systems, with suitability for critical applications such as nuclear power plants. As a slave module for the ESB bus, it extends the reach of optical ESB bus networks to support reliable data transmission in industrial environments.

Key physical specifications include dimensions of 81mm width, 117mm height, and 116mm length. It features ST local bus connections and ST local bus connectors, with a transmission speed of 500 kBit/s using copper cable transmission principles. Electrical characteristics include 500V AC 50Hz withstanding capability for 1 minute for both the test section bus/input and sensor power/ground wires; it draws 9V DC power communication voltage from the ST local bus, and supports a 24V DC I/O voltage.

For wiring, the module uses screw connections for terminal base wire attachment, accommodating rigid and flexible wires with cross-sections ranging from 0.2 square meters to 2.5 square meters, equivalent to AWG 24 to 12 gauge. This module is engineered to maintain signal integrity over extended bus runs, making it ideal for large-scale industrial automation setups requiring stable, long-distance data communication.
