METZ CONNECT Analog Signal Converter KMAi-F8 Spring-Force Terminal (110731)

With an accuracy of less than 0.2% of full scale, the METZ CONNECT KMAi-F8 analog signal converter delivers precise signal conversion for industrial automation. This DIN-rail mounted device transforms RTD sensor inputs (Pt100, Pt1000, Ni100, Ni1000, NTC, PTC, potentiometer) into standard analog outputs (0-10V, 0-20mA, 4-20mA) selectable via DIP switches. Its 3-way isolation ensures signal integrity and safety, while spring-force terminals allow quick, tool-free wiring. Operating from 18-30V DC, it consumes less than 1.5W and withstands temperatures from -25°C to +70°C, making it suitable for demanding environments.

Overview

The KMAi-F8 is a compact, single-channel analog signal converter engineered for reliable signal conditioning in control panels and machinery. It accepts a wide range of temperature sensors and potentiometers, converting their signals into industry-standard voltage or current outputs. Configuration is straightforward using DIP switches, eliminating the need for software. The device provides galvanic isolation between input, output, and supply, protecting connected equipment from interference and ground loops. Its push-in spring-force terminals reduce installation time and ensure vibration-resistant connections. Housed in a polyamide enclosure with IP20 protection, it is designed for DIN rail mounting (TS35) in electrical cabinets.
