YOKOGAWA ISC40S-GG-T3-05 Central control module

Yokogawa Input Modules Overview

Yokogawa provides a variety of input modules for its industrial automation systems, particularly Distributed Control Systems (DCS) and Programmable Logic Controllers (PLCs). These modules are used to receive various signals from field devices (such as sensors, transmitters, switches, etc.) and convert these signals into a digital format that the control system can process.

Product Detailed Description

Yokogawa's input modules come in various types depending on the signal type being received and the system requirements. Common types include:

• Analog Input Modules:

• Receive analog signals (such as 4-20mA, 0-5V, 0-10V) from transmitters measuring temperature, pressure, flow, etc.

• Convert these analog signals into digital values for use by the control system.

• Typically offer high accuracy and resolution.

• Digital Input Modules:

• Receive discrete signals (such as 24V DC, 110V AC) from devices like switches and proximity sensors.

• Detect the ON/OFF status of these signals.

• Can be configured to detect Normally Open (NO) or Normally Closed (NC) contacts.

• RTD/Thermocouple Input Modules:

• Receive temperature signals from Resistance Temperature Detectors (RTDs) and thermocouples.

• Perform signal conditioning and linearization to convert them into temperature values.

• Support various types of RTDs and thermocouples.

• High-Speed Counter Modules:

• Used to receive fast pulse signals from encoders or other pulse-generating devices.

• Used for measuring speed, frequency, or position.
