METZ MR-F-AO4 módulo de saída analógica Modbus RTU, 4 canais, RS485, 16 bits, calha DIN 110835130270

Four 16-bit analog output channels with 3-way isolation and Modbus RTU over RS485 make the METZ MR-F-AO4 a precise actuator interface for industrial automation.

Overview

The METZ 110835130270 MR-F-AO4 is a Modbus RTU analog output module that converts digital commands into analog signals. It provides four individually configurable channels, each capable of voltage (0-10 V, ±10 V) or current (0-20 mA, 4-20 mA, ±20 mA) output. The module communicates over RS485 with baud rates from 1200 to 115200 bps and supports none, even, or odd parity with 1 or 2 stop bits. Configuration is done via DIP switches and Modbus registers.

What stands out

• Four 16-bit analog outputs for precise control
• 3-way isolation between supply, RS485, and analog outputs
• Wide supply range: 18-30 V DC, max 2.5 W consumption
