Product Details：

Product Dimensions：

RELIANCE analog modules are designed to interface industrial control systems, such as Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS), with analog signals from field devices and to send analog control signals to actuators. These modules are crucial for monitoring and controlling continuous variables like temperature, pressure, flow, level, and speed.

Product Details

Functionality:

Analog Input Modules: Receive continuous electrical signals (typically voltage or current) from field sensors and convert them into digital values that can be processed by the control system.
Analog Output Modules: Receive digital values from the control system and convert them into continuous electrical signals (typically voltage or current) to control analog actuators like valves, drives, and positioners.

Types (Common Examples):

Analog Input (Voltage): Accepts voltage signals within a specific range (e.g., 0-10V, +/-10V).
Analog Input (Current): Accepts current signals, most commonly 4-20mA.
Analog Output (Voltage): Outputs voltage signals within a specific range (e.g., 0-10V, +/-10V).
Analog Output (Current): Outputs current signals, typically 4-20mA.
Thermocouple/RTD Input Modules: Specialized for direct connection to temperature sensors, with built-in cold junction compensation and linearization.

Key Features (General):

High resolution and accuracy in signal conversion.
Electrical isolation between channels and the backplane.
Filtering capabilities to reduce noise.
इंडिकेशन LEDs for status and diagnostics.
Configurable parameters (e.g., input range, filtering).
Robust design for industrial environments.
Compatibility with RELIANCE control systems (and potentially others).
