The 1746-IB32 SLC 500 24 Volt DC Digital Output Module by Allen-Bradley is a 32-point current sinking input module with 24 Volt DC input voltage with an 8-point group per common. It has a temperature-dependent sinking voltage range of 15 to 30 Volt DC at 50 degrees Celsius and 15 to 26.4 Volts DC at 60 degrees Celsius and has an overall backplane electrical rating of 0.050A at 5 Volts DC and 0.0A at 24 Volts DC ngokulandelana. The 1746-IB32 offers isolation from the backplane tested at 1500 Volts AC for 60 seconds between the backplane and the I/O and it has a 1500 Volt AC dielectric withstand. The 1746-IB32's 32-input point is electrically-fused for protection over the external wiring and it has a maximum of a single 2.5A non-replaceable fuse per common.

The Allen-Bradley 1747-BSN is a backup scanner module. The 1747-BSN backup scanner is available with redundancy for remote I/O (RIO). I-1747-BSN ifakwe ukushintshwa kwesiteshi se-RS-232 sokuxhumana namadivayisi afana nokuxhumana kwe-opharetha. Le module nayo inesixhumanisi se-DH +. Le module iqoqo lamamojula ahambisanayo, eline-module elilodwa elitholakala ohlelweni oluphambili namanye amamojula ohlelweni lwesibili noma lwesipele. The main module controls all the remote I/O operations.
