Allen-Bradley 1746-OB32
SLC 500 Digital DC Output Module (32-Channel)
Product Overview
The 1746-OB32 is a 32-channel digital DC output module from Allen-Bradley’s SLC 500 series. It is designed for high-density, low-current applications and supports DC voltage ranges from 5 to 50V DC, with a nominal output of 24V DC. With sixteen (16) points per common, it allows efficient discrete output control in industrial automation systems. Each output channel can supply up to 0.5A (depending on ambient temperature), with a total module current capacity of 8A.
Ideal for energizing pilot lights, buzzers, horns, solenoids, and relays, this module can also be used in interposing relay applications for AC loads or signal isolation. It features 32 onboard status LEDs, one for each output point, for easy diagnostics.
