FAQ
Q1: What is the Allen-Bradley 1746-IH16 used for?
The 1746-IH16 is a 16-point digital input module for Allen-Bradley SLC 500 PLC systems. It monitors high-voltage DC signals from compatible industrial switches, sensors, and control devices.
Q2: What input voltage does the 1746-IH16 support?
It is designed for nominal 125V DC signals and has an operating range of 90–146V DC.
Q3: How many input points does this module provide?
The module provides 16 digital input points, with all 16 points sharing a common.
Q4: What does sinking input mean?
A sinking input module is designed for a compatible DC wiring arrangement in which current flows into the input circuit from the field device. Check the wiring diagram and polarity requirements before connecting field signals.
Q5: What is the input response time?
The maximum specified signal delay is 9 ms for both the ON and OFF transitions.
Q6: How much backplane power does the module require?
It draws 85 mA from the 5V DC backplane supply and does not draw current from the 24V DC backplane supply.
Q7: Can all 16 inputs be switched on simultaneously?
The permitted number of simultaneous ON inputs depends on the input voltage and ambient temperature. At 125V DC and 60°C, all 16 inputs can be ON simultaneously. At higher input voltages, the allowable number may be lower.
Q8: What should be checked when replacing a 1746-IH16?
Confirm the SLC 500 chassis compatibility, 125V DC input requirements, wiring polarity, common-terminal arrangement, and current operating condition of the module. Because this is a legacy product, inspect used or refurbished units carefully before installation.
