Auxiliary Powered Signal Converters Introduction to the ACT20M Series ACT20M Series The Weidmüller ACT20M range of isolators and converters brings the benefits of technology development to signal isolators. This provides all the features required in isolators and converters in a space saving 6mm housing. Benefits include 2.5kV: 3 way isolation, accuracy to 0.05% with ambient operation of -25° to +70°C on most models. Simplified power supply wiring is achieved with direct connection or via the DIN Rail Bus to supply power to all modules. Applications Use the ACT20M Series for: • Isolation and conversion of input signals prior to control system • Splitting one input signal into two output signals for simultaneous outputs up to 300Ω per output • Standardisation of control system input cards utilising converters for nonstandard inputs • Providing electrical safety between field device faults and control system • Eliminating errors in the control signal caused by ground loops • One product required for all signal requirements Standard features of the ACT20M Range Include: General Data D.6 Supply voltage 24V DC ± 30% Storage temperature -40°C ... +85°C Insulation voltage 2.5kV Rated voltage 300V Pollution degree 2 Overvoltage category III IECEx ratings Ex nA IIC T4 Gc Length x Width x Height 114.3 x 6.1 x 112.5 mm Clamping range 2.5 / 0.5 / 2.5 (nominal / min. / max.) mm² Output load impedance 0-600Ω or 2 x 300Ω WAUS Signal Products Main Line 2013 Auxiliary Powered Signal Converters Auxilary Powered, Universal Signal Isolator/Converter + + + Output Tx - + - + V mA - - Input - + Supply + - Supply ACT20M-UI-AO-S Connections ACT20M-UI-AO-S The ACT20M-UI-AO-S is the flagship model.

This is the simplest method of isolating the signal passed from one device to another to eliminate electrical interaction between them. It is often used to fix unexpected loop isolation problems as it requires no additional wires to be installed. You simply break the problem loop and install the device.
