SELF-POWERED LOOP ISOLATOR ARDETEM Coding 1 channel loop isolator ARDETEM reference: ATIS-H SFERE reference: ELIT93-H 2 channel loop isolator ARDETEM reference: ATI2S-H SFERE reference: ELIT940-H • The ATIS/ELIT solves common point problems which may occur on the measure loops and also reduces the rejection of the disturbances induced on the cables. • The ATIS/ELIT isolates the sensors or transmitters from the process receivers PLC's, recorders, etc.) • The transparency to the HART protocole allows the user to communicate with the digital protocole HART via the ATIS/ELIT. • HART PROTOCOLE TRANSPARENCY • 1 or 2 isolated measure channels • Isolation between input / output • Transfer ratio 1 / 1 • High transmission accuracy • High load impedance • Powered by the input signal • Reduced dimensions ons Insulation of current loops. Insulation of measure transmitters from the PLC boards. Insulation of 4-20mA signals from thermocouples which may start to have insulation problems when the temperature increases. Application example with a temperature sensor with hart digital output: 24 Vdc supply insertion pyrometer t° sensor with HART digital output I = 15mA T° = 150°C —TLTL HART communication HART console The ATIS/ELIT transmits the measure information in the form of a DC current, + the HART digital pattern with a galvanic partition of 2kV.
