The 1756-IF4FX0F2F is an Allen-Bradley (Rockwell Automation) ControlLogix analog input module. Here’s a breakdown of its key features and specifications:
Module Details:
Series: ControlLogix (1756 platform)
Type: Analog Input Module
Model: 1756-IF4FX0F2F
Channels: 4 isolated analog inputs
Input Types: Voltage (±10V DC) and current (0–20 mA or 4–20 mA)
Resolution: 16-bit (high precision)
Isolation: Channel-to-channel and channel-to-backplane isolation for noise immunity
update Rate: Configurable per channel (up to 1 ms per channel)
Diagnostics: Over/under-range detection, open wire detection (for current inputs)
Connector: Removable screw terminal (RTB) or 16-pin Euro-style connector
Key Features:
Flexible Input Ranges: Supports both voltage (±10V) and current (0–20 mA, 4–20 mA) signals.
Isolated Channels: Prevents ground loops and improves signal integrity.
High Resolution: 16-bit ADC for precise measurement.
Configurable Filtering: Adjustable filtering to reduce noise.
Open Wire Detection: Alerts if a current loop is broken (for 4–20 mA inputs).
LED Indicators: Status LEDs for power, communication, and channel activity.
Typical Applications:
Process control (pressure, temperature, flow monitoring)
Industrial automation (machine monitoring, feedback systems)
Data acquisition systems
Compatibility:
Works with ControlLogix chassis (1756-A4, A7, A10, etc.)
Programmable via RSLogix 5000 or Studio 5000 (Rockwell’s PLC programming software)
Wiring Notes:
Voltage Inputs: Wire to terminals (+/-) with proper shielding.
Current Inputs: Requires external 24V DC loop power or use of 2-wire transmitters.
Termination: Uses a 1756-TBCH or similar terminal block.
Ordering Information:
Catalog Number: 1756-IF4FX0F2F (Firmware version-specific variants may exist)
