Buy & Import 16 Channel 4-20mA to Modbus/RS232/RS485 A/D Converter from Shenzhen Sunyuan Technology Co., Ltd. - Wholesale Supply

This 16-channel analog-to-digital converter from Shenzhen Sunyuan Technology Co., Ltd. is designed for industrial signal isolation and long-distance transmission. It accepts a broad selection of voltage and current inputs, including 0-5V, 0-10V, 0-75mV, 0-±10V, 0-20mA, and 4-20mA signals, converting them for output over RS-485 or RS-232 interfaces. The module operates within a temperature range of -45°C to +80°C and has physical dimensions of 58mm x 87.5mm x 59mm.

The converter's architecture includes power supply isolation, signal linearization, and an integrated A/D conversion circuit. Each RS-485 serial port can connect up to 256 of these Isoad series modules, using either a character communication protocol or Modbus RTU. All user configuration, such as calibration values, address, baud rate, and data format, is stored in non-volatile EEPROM memory, ensuring settings persist through power cycles.

These modules are commonly sourced for integration into monitoring and control systems in manufacturing plants, process automation, and environmental monitoring. Buyers include system integrators and industrial equipment manufacturers requiring reliable signal conditioning. When ordering, confirm the specific input range (e.g., 4-20mA or 0-10V) and the desired output interface (RS-485 or RS-232) to match your existing control architecture.

Frequently Asked Questions About 16 Channel 4-20mA to Modbus/RS232/RS485 A/D Converter from Shenzhen Sunyuan Technology Co., Ltd.
The baud rate is user-configurable. You should specify your required baud rate (e.g., 9600, 19200, 38400) when placing your order, as it is stored in the module's non-volatile memory during configuration.

Sourcing 16 Channel 4-20mA to Modbus/RS232/RS485 A/D Converter from Shenzhen Sunyuan Technology Co., Ltd. - China Import Guide

Before placing an order for these A/D converters, verify the exact input range configuration you need for each channel, as this determines the model suffix. Confirm with Shenzhen Sunyuan Technology Co., Ltd. whether the RS-485 or RS-232 output version is in stock for your desired quantity, and request the current lead time for production or shipment.

For logistics, clarify the shipping terms (e.g., EXW, FOB Shenzhen) and the expected transit time to your destination. Since the module stores configuration in EEPROM, ask the supplier if they can pre-configure addresses or baud rates for your batch to simplify your installation process.

Upon receipt, a quality check should include verifying the physical dimensions match the 58 x 87.5 x 59mm specification and testing a sample module's communication on your RS-485 network. Ensure the isolation voltage rating of 3000 VDC is suitable for your installation environment, and confirm the operating temperature range of -45°C to +80°C meets your site's conditions.
