This 16-input voltage analog I\/O module delivers precise signal conversion with 16-bit resolution and programmable filtering, making it an ideal replacement for older modules requiring ±10V, 0-10V, or 1-5V DC signals. Designed for the SLC 500 platform, the 1746-NI16V occupies a single slot (except slot 0) and integrates seamlessly with the backplane.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 16 voltage channels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution:\u003c\/strong\u003e 16 bits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBandwidth:\u003c\/strong\u003e 6–250 Hz (programmable filter frequencies: 6, 10, 20, 40, 60, 80, 100, 250 Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Types:\u003c\/strong\u003e ±10V DC, 1-5V DC, 0-5V DC, 0-10V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackplane Current:\u003c\/strong\u003e 125 mA at 5V; 75 mA at 24V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation:\u003c\/strong\u003e 500V AC for 1 second\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConversion Type:\u003c\/strong\u003e Sigma-Delta\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Response:\u003c\/strong\u003e 9–630 ms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 20 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e −25 to 60 °C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplication Scenarios\u003c\/h2\u003e\u003cp\u003eIn process control environments, the 1746-NI16V handles analog signals from pressure transmitters, temperature sensors, and flow meters. For example, a chemical plant upgrading from a 12-bit module can achieve finer resolution for batch control. In packaging machinery, the module’s programmable filter rejects electrical noise, improving signal integrity on high-speed lines. Its 500V isolation protects downstream PLC logic in industrial settings with ground potential differences.\u003c\/p\u003e\u003ch2\u003eInstallation Guide\u003c\/h2\u003e\u003cp\u003eMount the Allen-Bradley 1746-NI16V in any SLC 500 I\/O slot except slot 0 (reserved for the processor). Use the 1746-RT25G terminal block or pre-wired cables (Belden #8761 or equivalent) with Allen-Bradley 1492-AIFM8-3 or 1492-AIFM16-F-3 termination blocks. Always disconnect power before inserting or removing the module to prevent arcing. The module fits local or expansion chassis, occupying one slot.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe 1746-NI16V communicates with SLC 500 processors via the parallel backplane interface, drawing power from the chassis power supply. It works with all SLC 5\/02, 5\/03, 5\/04, and 5\/05 controllers. For applications needing isolated analog inputs, this module integrates directly without additional signal conditioners—simplifying system architecture. It is UL listed, C-UL approved, and CE compliant for Class I Division 2 hazardous locations.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing, verify your system voltage requirements (5V and 24V backplane currents available) and confirm slot availability in your SLC 500 chassis. The 1746-NI16V accepts voltage inputs only—for current inputs, consider the 1746-NI4I or 1746-NI8I.
