DIN Rail 2000V Isolated 24-Channel DC Voltage Current Acquisition Module with Modbus RTU/TCP
Product Overview
This product is a high-precision real-time measurement module for 24 channels of DC voltage and current signals or AC/DC universal signal acquisition. Each channel uses an independent 24 bit AD chip and each channel is isolated from each other for true effective value measurement and 24 channel synchronous sampling detection. It has high accuracy, good stability, and fast sampling speed; Ethernet or RS485 communication options are available. Widely used in industries such as aging testing equipment and production automation testing support.

FAQ
Q1: Do these modules feature internal data logging storage?
A1: No. These are real-time acquisition and transmission modules designed to stream parameters instantly to a PLC, SCADA, or upper computer via Modbus. They do not contain internal flash storage for historical data logging.
Q2: Can I combine both voltage and current inputs in the 24-channel version?
A2: Yes. Model ZH-44243G-*4F2/#V*#A is specifically designed as a 24-channel combination collector supporting mixed voltage and current measurements.
Q3: What communication interfaces are available?
A3: The units support standard RS485 (Modbus-RTU) and optional RJ45 Ethernet (Modbus-TCP) network communication.
Q4: How are the devices configured?
A4: You can configure communication parameters and addresses via either onboard hardware DIP switches or software commands.
