Product Details：

Product Dimensions：

Eaton Relay Input Modules are crucial components in industrial automation systems, designed to interface between field devices and control systems. They provide a reliable means of detecting and transmitting digital signals, often used to monitor the status of switches, sensors, and other devices.

Product Details

Functionality:

These modules receive input signals from field devices and use electromechanical relays to provide electrical isolation and signal amplification.
They convert the input signal into a format suitable for the control system, typically a digital signal.
The relay aspect of these modules provides electrical isolation between the field devices and the control system. This helps to protect sensitive control electronics from voltage spikes and other electrical disturbances.

Types:

Eaton offers a variety of relay input modules with different voltage ratings, number of channels, and relay contact configurations.
These modules can be used for both AC and DC input signals.
Variations include differing amounts of input channels per module.

Key Features:

Electrical isolation between field devices and control systems.
Robust design for industrial environments.
LED indicators for status monitoring.
Variety of voltage ratings and contact configurations.
Compatibility with various industrial control systems.

Product Parameters

Voltage Ratings:

Input voltage ranges vary depending on the module type (e.g., 24V DC, 120V AC, 230V AC).
