Allen-Bradley 1746-FIO4I Fast Analog Combination Module

The Allen-Bradley 1746-FIO4I is a fast analog combination module designed for use with the SLC 500 series. This module features two (2) analog input channels with 12-bit resolution, configurable for 0-20 mA or 0-10 VDC input signals, and two (2) 0-20 mA analog output channels with 14-bit resolution. It supports both fixed and modular SLC-500 hardware, and is particularly useful for applications with limited expansion space, as it combines both analog input and output functionality in a single module.

Key Features & Specifications:

• Inputs: Two (2) voltage or current inputs (0-10 VDC or 0-20 mA)
• Outputs: Two (2) 0-20 mA analog outputs
• Input Channels: 12-bit resolution, selectable voltage or current inputs, with a maximum voltage of ±7.5V DC and maximum current of 30 mA.
• Output Channels: 14-bit resolution, 0-20 mA range, 21 mA full-scale output, 5% overrange capability.
• Accuracy: ±0.440% of full scale @ 25°C for input, ±0.298% for output at 25°C.
• Conversion Time: 7.5 µs every 512 µs, with a 100 µs step response for inputs and 2.5 ms for outputs at 95%.
• Bandwidth: 7 kHz
• Resolution: 12 bits for inputs, 14 bits for outputs
• Update Time: 512 ms
• Wiring: Shielded, Belden #8761 (recommended), with a max wire size of 14 AWG (2.5 mm²)
