AutomationDirect FC-B34 NSNBC01 Programmable Logic Controller Module

The FC-B34 is an isolated, single‑channel signal conditioner from AutomationDirect that converts a bipolar input signal into a unipolar output suitable for PLC analog inputs. It accepts a bipolar voltage input with ranges such as ±100 mV, ±50 mV, ±5 V, ±10 V, and ±15 V, and provides a configurable output channel that can drive either current (0–20 mA or 4–20 mA) or voltage (0–10 VDC or 0–5 VDC). The unit operates from 24 VDC and features a fully isolated input/output path to protect the controller and minimize ground loops. It mounts on a 35 mm DIN rail or panel, with removable screw-terminal plugs for easy wiring, and includes a 4-position terminal block attached to the module plus a 2-position terminal block and a data sheet insert. Constructed with a plastic housing for compact panel or DIN‑rail installations, the FC-B34 is RoHS-compliant and EU REACH compliant. This signal conditioner is commonly used to condition and isolate sensor signals for PLC or process instrumentation, enabling reliable translation of bipolar sensor outputs to PLC‑friendly unipolar signals.
