IC694MDL930

Description

1. Product Overview

2. Technical Specifications

• Input Channels: The module usually features a set number of input channels, for example, 8 channels. This allows it to connect to multiple analog sensors simultaneously, providing comprehensive data collection for a single process or multiple related processes.
• Input Signal Range: It can accept a wide range of analog input signals. Common ranges include 0 – 10V, 4 – 20mA, – 10 – 10V, etc. This flexibility makes it compatible with a variety of sensors that output different signal levels.
• Resolution: It offers a high – resolution analog – to – digital conversion, typically 12 – bit or 16 – bit. Higher resolution means more precise measurement of the analog signals, allowing for more accurate control of industrial processes. For instance, a 16 – bit resolution can detect smaller changes in a temperature sensor’s output compared to a lower – bit resolution.
• Accuracy: The module provides a certain level of accuracy in converting analog signals to digital values. For example, it may have an accuracy of ±0.1% of the full – scale range. This ensures that the data sent to the PLC is reliable and representative of the actual physical variable being measured.
• Isolation: Electrical isolation is provided between the input channels and between the inputs and the power supply. The isolation voltage is often around 2500V AC. This isolation protects the PLC from electrical interference and surges in the sensor circuits, enhancing the overall reliability of the system.
• Power Supply: It requires a 24V DC power supply with a tolerance of ±10%. This standard power requirement simplifies the integration of the module into existing industrial electrical systems.
• Operating Temperature Range: The module can operate within a temperature range of – 20°C to 60°C. This wide temperature tolerance allows it to be used in various industrial environments, from cold storage facilities to hot manufacturing plants.
• Dimensions: It is designed to fit into the Series 90 – 40 PLC chassis. The dimensions might be approximately 170 mm in length, 70 mm in width, and 120 mm in height.
• Weight: It is relatively lightweight, typically around 0.5 kg, which makes it easy to handle and install.
