Product Summary
The Allen-Bradley 1794-OB32P delivers thirty-two electronically protected 24V DC sourcing outputs. This module safeguards each channel individually against overloads. It drives pilot lamps, relays, and solenoid valves with precision. Engineers gain robust control for demanding industrial applications using this Flex I/O component.
Product Procurement & Buyer Guide
Why Choose Electronic Protection for Your System?
The 1794-OB32P integrates individual electronic fuses on every channel. This design eliminates the need for external fuses. It drastically reduces panel space and wiring complexity. You minimize costly downtime during fault conditions. The module automatically protects downstream devices from damage.
Understanding the Dual-Group Power Architecture
This module splits its 32 outputs into two groups. Channels 0 through 15 share a dedicated voltage source. Channels 16 through 31 use a separate power input. This group isolation allows you to power different load types independently. You can manage high-current devices on one group safely.
Matching Current Ratings to Your Application
The total module current reaches 14.0 Amperes. Group one handles a maximum of 6 Amps. Group two supports up to 8 Amps for demanding loads. Each individual channel delivers up to 500mA. This configuration perfectly suits high-density solenoid or indicator banks.
Compatibility with Terminal Base Units
The module requires either the 1794-TB32 or 1794-TB32S terminal base. These bases provide the physical connection to field wiring. They ensure a secure and reliable electrical interface. You must select the correct base for your wire size needs. Both options guarantee proper module fit and function.
Installation and Mounting Configuration
You mount the unit easily on a standard DIN rail. The open-type enclosure allows for flexible cabinet placement. The compact dimensions of 1.8 x 3.7 x 2.1 inches save space. Thirty-two yellow status LEDs provide immediate visual feedback. This setup simplifies commissioning and ongoing system checks.
Operational Voltage and Performance Parameters
The module operates with an on-state voltage from 10V to 31.2V DC. It delivers fast switching with a 0.5ms turn-on delay. The turn-off delay reaches a maximum of only 1ms. This speed ensures quick response for critical control sequences. The low 0.5V DC voltage drop maximizes efficiency.
