Allen Bradley 1794-OB32P 24VDC Output Module 32 Channels

The AB 1794-OB32P is a FLEX I/O digital 24V DC module featuring 32 electronically fused outputs grouped into 2 groups of 16 outputs, each with separate voltage sources. This module provides self-protection against temperature overloads and shocks.

Key features include:

• 32 yellow status indicators
• Compact dimensions: 1.8 x 3.7 x 2.1 inches
• DIN rail mounting compatible
• Requires 1794-TB32 or 1794-TB32S terminal base units
• On-state output voltage range: 10V DC to 31.2V DC
• Maximum on-state output voltage drop: 0.5V DC
• Current output: 1 mA to 500 mA per channel (14A total per module)
• Group current ratings: 6A (Channels 0-15) and 8A (Channels 16-31)
• Maximum output surge current: 2A for 50ms (repeatable every 2s)
• Off-state output leakage current: 0.5 mA
• External DC supply range: 10-31.2V DC with 5% AC ripple
• Fast response times: 0.5ms OFF to ON, 1ms ON to OFF
• Continuous isolation voltage: 50V between field and system
• Thermal dissipation: 18.1 BTU/hr at 31.2V DC
• Power dissipation: 5.3W at 31.2V DC

The 1794-OB32P is a sourcing discrete output module ideal for controlling 24V DC components including indicating devices, sounding devices, and electrical loads such as relay coils and solenoid-actuated devices.
