Allen-Bradley 1746-FIO4V Overview
The Allen-Bradley 1746-FIO4V is a fast analog combination module built for the SLC 500 controller platform. It offers two configurable input channels and two voltage output channels in a single unit. This design helps engineers save rack space while handling mixed signal types. The module supports current inputs from 0 to 20 mA and voltage inputs from 0 to 10V DC. Its output range spans -10 to +10V DC, making it flexible for many control tasks.
Key Technical Specifications
This module delivers 12-bit input resolution and 14-bit output resolution. The update time is 512 microseconds, and the step response is 100 milliseconds for inputs and 2.5 milliseconds for outputs. It draws 55 mA from the 5V backplane and 150 mA from the 24V backplane. The bandwidth is 7 kHz, which suits fast analog applications. The module also provides 500V DC isolation between field wiring and the backplane.
Input and Output Configurations
You can set each input channel for current or voltage. For current, the nominal range is 0 to 20 mA, with a maximum of 30 mA. For voltage, choose 0 to 5V, 1 to 5V, or 0 to 10V DC. The output channels support standard voltage ranges, including 0 to 5V, 1 to 5V, 0 to 10V, and -10 to +10V DC. This flexibility lets you interface with sensors, valves, VFDs, and recorders.
Installation and Environment
Mount the 1746-FIO4V in a chassis using 14 AWG wiring. Keep it away from high-voltage AC or DC lines to reduce electrical noise. Also, avoid placing it near the rack power supply or in areas with high ambient temperature. The module operates in non-condensing humidity from 5% to 95%.
Practical Applications
Use this module to read process variables and send control signals. It works well in closed-loop control, monitoring, and data logging. The fast update time makes it suitable for applications requiring quick response, such as motion control or high-speed sorting.
