Emerson SE4002S2T1B1 Discrete Output Card

Product Introduction

The Emerson SE4002S2T1B1 Discrete Output Card is an industrial automation module designed for controlling AC field devices through digital output signals. It is used in distributed control systems where reliable switching performance and stable process execution are required.

This module provides 8 independent output channels and supports 120V/230V AC high-side switching. It is designed to operate industrial loads such as relays, contactors, alarms, and other AC-driven equipment.

Each channel is electrically isolated, allowing independent switching operations and reducing interaction between output paths. This improves system stability and ensures consistent control performance in multi-channel industrial environments.

The module uses an 8-channel terminal block, providing a structured and organized wiring interface. This simplifies installation, reduces wiring complexity, and supports efficient maintenance in control cabinet systems.

The SE4002S2T1B1 is widely used in industrial sectors such as power generation, oil and gas, chemical processing, water treatment, and manufacturing automation systems.
