Feature: 1. Powerful Processor: The programmable logic circuits PLC control board features the for WS3U processor with a 32 bits chip, delivering fast computing speeds and ample storage space for efficient operatings. 2. Reliable Communicating: With a download speed of 38.4Kbps (can be adjusted to 9.6Kbps in special circumstances), the programmable logic module controller unit supports direct programming, downloading, debugging, and monitoring with for GX Developer or for GX Works2 software. 3. Efficient Power Supply: The PLC controller industrial control board operates on DC 24V power supply. It has a static current of 30mA when output relays are not activated, with an increase of 10mA for each activated relay. The total current draw when all relays are open on the for 3U‑14MR model is 70mA (1.44W). 4. Versatile Load Capabilities: Equipped with 5A current relays, the programmable controller relay delay module is designed for long term use below 3A. The transistor based outputs can drive up to 1A of current, with a continuous usage limit of 500mA. 5. Comprehensive Features: The PLC programmable logic controller comes with 6 built in analog inputs, 3 voltage inputs ranging from 0‑10V, 3 current inputs ranging from 0‑20mA, and 2 analog outputs (0‑10V voltage). It also includes 2 60K count high speed inputs, support for 3 AB phase inputs, and up to 8 channels of 100K pulse outputs for versatile control and monitoring applications.

For MODBUS: Built In Clock: Built In. Package List: 1 x PLC Control Board Note: Installation and Usage Guidelines: 1. To prevent overheating, please install the machine in a wall mounted manner. Sufficient space should be left above and below for heat dissipation. 2. Maintain a gap of at least 50mm between the programmable controller host and other equipment or structures. Keep away from high voltage lines, high voltage equipment, and power equipment as much as possible. 3. Avoid dust, oil pollution, erosive environments, pay attention to electrostatic guard (avoid direct contacting of hands with circuit board lines). 4. Use rubber isolation columns for fixation.
