Product information
Product information The ACT20P-UI-AO-DO-LP-X converts and isolates current, voltage, potentiometer and temperature sensor
signals (mA, A, mV, V, potentiometer, RTD and TC). The transmit function between the input and output can be
set via the configuration program either to predefined functions (x0.5, x, x2) or via a freely definable function
table. The device is powered via the output current loop.
Features
• Configuration and monitoring are performed via FDT/DTM-Software „WI-Manager“.
• The active or passive signal inputs for RTD, TC, potentiometer, mV, V, mA and A are completely electrically
isolated.
• The TC signal input has internal cold-junction compensation.
• Alarm output (for example, for limit monitoring, sensor error detection and more)
• 3-way galvanic isolation between input, output/supply and alarm output.
