Technical Specifications Field‑side analog signal input, isolated standardized analog output. Auxiliary DC power supply for module operation. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Galvanic isolation between input and output channel.
Functional Features Completes galvanic isolation between field sensor circuit and control‑system circuit. Realizes analog signal filtering and level matching conversion. Front‑panel LED indicator displays module power‑on status. Supports continuous signal transmission under industrial interference environment.
Application Scenarios Spare signal conditioning module for industrial automation cabinet. Used for field sensor signal isolation processing in DCS and PLC system.
Performance Parameters Low‑distortion analog signal transmission performance. High‑isolation voltage withstand capability. Reliable industrial anti‑interference characteristic.
Material Composition Flame‑retardant plastic DIN‑rail module housing. Multilayer glass‑fiber epoxy printed circuit board. Isolation assembly, signal filtering and level conversion circuit. Screw‑type input‑output wiring terminals and DIN‑rail buckle.
Structural Characteristics Compact DIN‑rail module structure. Top and bottom edges equipped with screw‑type wiring terminals. Rear side with DIN‑rail fixing buckle. Power‑on status LED arranged on front surface.
Working Principle SCM‑1 obtains auxiliary working power. Field analog input signal passes through isolation and filtering circuit, converts to standardized analog output signal, and transmits to control‑system I/O module. Galvanic isolation blocks ground loop interference between field and control cabinet.
Installation Requirements Disconnect field sensor signal and module auxiliary power before replacement. Snap SCM‑1 onto standard DIN‑rail inside cabinet. Complete field‑side input wiring and control‑side output wiring. Restore auxiliary power supply, measure output signal value, verify signal conversion accuracy.
Usage Notes Signal wiring polarity must be correct. Hot‑plug under powered condition is prohibited. Confirm isolation voltage rating matches site environment requirement.
