The S1SD-1AI-2U is a 1-channel isolating amplifier and signal splitter from Pepperl+Fuchs. It supplies 2-wire transmitters, processes current or voltage input signals, and provides two identical isolated outputs configurable as 0/4-20 mA, 0/1-5 V, or 0/2-10 V. This device ensures reliable signal transmission with galvanic isolation between field and control circuits.

Q1: What is the main function of the S1SD-1AI-2U?
A1: It powers a 2-wire transmitter, receives its 4-20 mA signal (or a 0-10 V signal), and splits it into two identical, isolated output signals for sending to two separate control devices .
Q2: What types of output signals does it provide?
A2: It provides two outputs, each configurable for 0/4-20 mA, 0/1-5 V, or 0/2-10 V signals .
Q3: What are the supported input signal types?
A3: The module accepts 0/4-20 mA signals from 2-wire transmitters or 0/2-10 V signals from voltage sources .
Q4: How is the S1SD-1AI-2U powered?
A4: It can be powered via its screw terminals or through the optional Power Bus system for easier wiring.
