METZ CONNECT ADU-C12C12 analógovo-digitálny prevodník, 2-kanálový, RS485 Modbus RTU, DIN lišta 11043513

For industrial signal conversion where reliability and isolation are non-negotiable, the METZ CONNECT ADU-C12C12 stands apart with its 3-way galvanic isolation and configurable analog inputs. Unlike basic converters, this module accepts both voltage and current signals, making it adaptable to a wide range of sensors and control systems. With 12-bit resolution and Modbus RTU over RS485, it delivers precise, noise-immune data communication in demanding environments.

Highlights

• 2 configurable analog inputs: voltage (0-10V, 0-5V, ±10V, ±5V) or current (0-20mA, 4-20mA, ±20mA)
• 12-bit resolution for accurate signal conversion
• RS485 interface with Modbus RTU protocol
• 3-way isolation between input, output, and power supply
• Wide operating temperature range: -25°C to +70°C
• DIN rail mountable, IP20 protection

In daily use

Installation is straightforward: snap the module onto a standard DIN rail, wire your analog sensors, and configure via DIP switches or Modbus commands. The device operates from a 10-30V DC supply, and its isolated design prevents ground loops and interference. The RS485 port allows multi-drop networking, enabling up to 32 devices on a single bus. With a response time under 100 ms, it is suitable for real-time monitoring and control tasks.
