Detailed Description:
-
High-Density I/O Integration & Flexible Control: The module provides a total of 32 I/O points (16 inputs / 16 outputs) on a standard-width module. Its 16 digital outputs are relay type, with each relay contact capable of independently controlling AC or DC loads. This offers great flexibility for controlling loads of different natures such as solenoid valves, contactors, motor starters, and pilot lights.
-
Reliable Signal Acquisition: All 16 digital inputs accept 24V DC signals and support sink/source wiring, allowing reliable connection to various field switches and sensors.
-
Strong Load Adaptability: Relay outputs allow direct switching of load currents up to 2A, with a wide load voltage range (5-30V DC or 5-250V AC). This enables driving various actuators without the need for intermediate relays, simplifying peripheral circuits.
-
Electrical Isolation: Electrical isolation is provided between relay output channels, between outputs and inputs, and between them and the PLC’s internal circuitry. This effectively prevents interference and protects the PLC core.
-
Plug-and-Play & Easy Installation: The module connects to the S7-200 SMART CPU via a right-side bus connector and is powered by the system. All I/O points use removable screw-type terminals for convenient wiring and maintenance. Configuration is automatic using STEP 7-Micro/WIN SMART software.
-
Industrial-Grade Durable Design: The module is robustly designed for environments with vibration and electrical noise. The relays have a long mechanical life, meeting the reliability requirements of industrial applications.
