MTL CPY-C3-RAI141 Backplane Module

Product Description

The MTL CPY-C3-RAI141 is a backplane module engineered for the MTL4500 series intrinsic safety isolators. It provides seamless integration of Yokogawa analog input modules, supporting up to 16 channels of 4–20 mA signals. This module ensures safe, reliable signal transmission in hazardous areas, making it ideal for distributed control systems, emergency shutdown systems, and fire & gas monitoring applications. Moreover, its compact backplane design simplifies installation and reduces wiring complexity.

The module supports both single-channel and dual-channel MTL isolators, enabling flexible and redundant configurations for critical loops. In addition, it maintains intrinsic safety compliance for explosive atmospheres and high packing density for maximum channel capacity. Its innovative flat transformer technology ensures high reliability while minimizing power consumption.
