AutomationDirect FC-33 Isolated Signal Conditioner

The AutomationDirect FC-33 Isolated Signal Conditioner is a field-configurable, single-channel signal converter with galvanic isolation that protects downstream equipment while mapping input signals to a matching isolated output. It accepts one input channel in either current (0–20 mA or 4–20 mA) or voltage (0–5 VDC or 0–10 VDC) and provides a corresponding isolated output on one channel, with the output selectable as current (0–20 mA or 4–20 mA) or voltage (0–5 VDC or 0–10 VDC). The device operates from a 24 VDC supply and is designed for 35 mm DIN rail or panel mounting, housed in plastic with removable screw-terminal plugs for straightforward wiring. The FC-33 is described as field-configurable, enabling you to tailor input and output ranges to your sensor and PLC or control-system requirements without swapping hardware, making it ideal for interfacing sensors to automation equipment while maintaining electrical isolation between input and output. Typical uses include isolating sensor signals in process control and instrumentation, converting common signal types for downstream instrumentation, and eliminating ground-loop issues in multi-point installations, all within a compact package that fits standard industrial mounting rails.
