1790D-0V16 24V dc 16 Sinking Output Base and Expansion Modules

Output Specifications (Allen‑Bradley Series)

• Output configuration – 16 non‑isolated sinking outputs for direct control of DC loads.
• On‑state voltage range – Minimum 10V dc, nominal 24V dc, maximum 28.8V dc matches field power requirements.
• Output current rating – 0.5 A maximum per output, 4.0 A maximum per common.
• On‑state voltage drop – 0.5V dc maximum ensures efficient power delivery to loads.
• Off‑state leakage – 0.5 mA maximum prevents false triggering when outputs are off.
• Output signal delay – Off to On: 0.5 ms max, On to Off: 1.0 ms max for fast response.
• Output indicators – 16 green status LEDs show real‑time output states per channel.
• Common type – 8 points per common with 2 COM groups for flexible wiring.

Wiring Configuration

• Field power connection – Wire Com 0 and Com 2 to Field Power (+) 24V dc; wire Com 1 and Com 3 to Field Power (-) GND.
• Internal connections – All Com 0 and Com 2 terminals connect internally; all Com 1 and Com 3 terminals connect internally.
• Connector type – 37-pin D-shell connector provides reliable, compact wiring interface.
• Wiring guidelines – Use appropriate gauge wires for 0.5A per output; observe common current limits of 4.0A maximum.
