About 1746-IB32

The 1746-IB32 SLC 500 24V DC Digital Output Module by Allen-Bradley is a 32-point current sinking input module with 24V DC input voltage with an 8-point group per common. It has a temperature-dependent sinking voltage range of 15-30V DC at 50 0C and 15-26.4V DC at 60 0C and has an overall backplane electrical rating of 0.050A at 5V DC and 0.0A at 24V DC respectively. The 1746-IB32 offers isolation from the backplane tested at 1500V AC for 60s between the backplane and the I/O and it has a 1500V 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 minimum voltage across its circuit in the ON state is 15.0V DC and in its OFF state, it has a maximum voltage drop of 5.0V DC and a maximum leakage current of 1.5mA. The 1746-IB32 module has a maximum signal delay time of 3ms across its inputs in the ON and the OFF mode and it has an overall nominal input current of 5.1 mA at 24V DC nominal voltage. It has a maximum 0.2W power dissipation on each input point and it has a 6.67 aggregate power dissipation on the module. The 1746-IB32 has an operating temperature bracket between 0 and 60 °C (32 and 140 °F) at 5-95% non-condensing humidity and it has an operational vibrational withstand of 1G at 5-200Hz and a shock rating of 30G.
