Isolated signal converter for process, temperatures, resistances and potentiometers. Output signal in 4/20mA and 0/10Vdc. Isolated 3 ways.

Configurable to measure 4/20mA and 0/10Vdc process signals, both active and passive. Provides excitation voltage to power the transducer when needed. Thermocouples J,K,N,E,T,R,S,C,B. Thermoresistances Pt100 (2 and 3 wires), Pt500 and Pt1000. Several NTC probes. Resistances and potentiometer signals.

Output signal configurable for 4/20 mA (active and passive) and 0/10 Vdc. Universal power supply from 18 to 265 Vac/dc. 3 way isolation between input, output and power circuits.

Customizables input and output signals ranges. Configuration through front push-button keypad and front display. Configurable information messages (input signal value, output signal value, configured label, signal percentage and process value). Manual "force" functions to generate low and high output signals, to validate remote instrumentation during installation. "Password" function to block non-authorized access to configuration menu. "SOS" mode to help on critical maintenance and repairs without affecting the manufacturing process.

Designed for industrial use, with potential integration into a wide range of applications. Optional customization.
