Description
OMRON K3NX‑AD1A‑FLK4
Technical Specifications: Analog input configurable for voltage or current signal; input range supports standard industrial analog signal levels; sampling rate high‑speed configurable; FLK4 terminal‑block connection mode; power‑supply DC24V; operating temperature ‑10‑55°C; storage temperature ‑25‑70°C; humidity 10‑90%RH without condensation; panel‑mount housing; digital LED display window; multiple status LED indicators; weight approx 140g.
Functional Features: Supports field analog‑transmitter signal acquisition; high‑brightness digital local readout for on‑site observation; parameter configuration via front‑panel keys; scalable alarm‑output functions; FLK4 screw‑terminal‑block wiring simplifies field‑connection work; compact panel‑mount structure fits standard control‑cabinet panel cut‑out dimensions; built‑in signal filtering suppresses industrial‑site noise interference.
Application Scenarios: Industrial‑site pressure, temperature, flow analog‑signal monitoring; production‑process physical‑quantity local display; sensor‑transmitter signal conversion and re‑transmission; control‑cabinet panel‑mount measurement display; spare‑part replacement for legacy K3NX‑series instrumentation.
Performance Parameters: High‑measurement accuracy within rated operating conditions; built‑in digital filter reduces signal‑jitter influence; meets industrial‑instrument electromagnetic‑compatibility requirements.
Material Composition: Black flame‑retardant plastic panel housing; internal FR‑4 PCB with analog‑digital conversion chip; high‑brightness digital LED display; FLK4‑type brass nickel‑plated screw‑terminal block; front‑panel membrane operation keys.
Structural Features: Standard panel‑mount rectangular housing; front‑side digital display window and setting keys; rear‑side FLK4 terminal‑block for power‑supply and signal wiring; housing‑mounting clips for fixing into cabinet‑panel cut‑out.
Working Principle: Field analog voltage or current signal enters through FLK4 terminal block. Signal passes through conditioning circuit and analog‑to‑digital conversion chip to convert continuous analog quantity into digital numerical value. Digital value drives front‑panel LED display for local readout. Internal logic unit executes comparison with set threshold values and triggers alarm‑output action when measurement value exceeds threshold.
Installation Requirements: Insert unit into standard cabinet‑panel cut‑out and fasten with mounting clips; perform wiring work under power‑off status; analog signal cables adopt shielded cables; separate analog‑signal wiring from high‑power motor cables; cabinet‑panel location avoids direct heat‑source radiation.
Usage Notes: Supply voltage must comply with DC24V rated specification; confirm input‑signal type and range match field transmitter output; avoid condensation and corrosive‑gas environment; check FLK4 terminal‑block screw‑tightness periodically.
