The 5B42 is an isolated process current input module that provides an isolated, regulated 20 V supply voltage, measures 4-20 mA process-current input signal, and generates an output of +1 to +5V or +2 to 10V. The module circuitry can withstand 240v rms at the input screw-terminals and is hot swappable.
The 5B42 is a single‑channel, isolated signal‑conditioning module that accepts 4‑20 mA process‑current inputs and provides regulated isolated supply voltage. It offers true three‑port isolation (input‑output‑power) with up to 1500 V rms isolation and delivers low‑noise, low‑impedance voltage outputs of +1 V to +5 V or +2 V to +10 V.
The modules are compact (2.27" × 2.37" × 0.595"), hot‑swappable, and can be mixed and matched on backplanes. They include built‑in filtering, protection against 240 V rms over‑voltage, and meet hazardous‑area (Class 1, Division 2) approvals. Detailed pin‑out diagrams, mechanical dimensions, and environmental ratings are provided.
