Product Overview
The Allen-Bradley 1771-IVN is a 32-point low-true digital input module for the PLC-5 platform. It accepts 10-30 V DC sinking inputs in four groups of eight, designed for applications requiring low-true logic compatibility with sourcing field devices.
Technical Specs
- Input points: 32 (4 groups of 8)
- Voltage category: 10-30 V DC
- Logic: Low true (sinking)
- Backplane current: 700 mA @ 5 V DC
- Wiring arm: 1771-WN
- Addressing: Supports 1/2, 1, and 2-slot addressing
Key Features
- High-density 32-point design reduces rack space per input point
- Group isolation limits fault propagation between input groups
- Low-true logic suits sinking-input applications
- Direct backplane interface with the PLC-5 processor
FAQ
- What does low-true mean? The inputs register as ON when the corresponding input image bit is cleared (0), opposite of standard high-true modules.
- Which wiring arm is required? The 1771-WN 40-terminal wiring arm.
- Is it compatible with PLC-2 or PLC-3? The 1771-IVN is designed for PLC-5 systems using 1771 I/O chassis.
Installation Guide
- Power down the 1771 I/O chassis.
- Insert the module into any slot except the leftmost (adapter/processor) slot.
- Attach the 1771-WN wiring arm and connect field wiring.
- Set the chassis addressing mode (1/2, 1, or 2-slot) per system design.
- Apply power and verify input status LEDs respond to field device states.
Selection Tips
- Select the 1771-IVN for low-true sinking inputs; use 1771-IBN for high-true applications.
- Confirm field device voltage stays within 10-30 V DC.
- Verify chassis power budget: 700 mA @ 5 V DC per module.
