Allen-Bradley 1734-OB8S POINT Guard I/O 8-Channel 24V DC Safety Output Module
Allen-Bradley 1734-OB8S is a POINT Guard I/O safety output module with eight solid-state outputs for POINT I/O (1734) systems.
Overview
The module provides eight solid-state safety outputs configurable for single-channel or dual-channel operation, switched from a 19.2-28.8V DC field power supply drawing 50 mA. Output current is 1 A per output at 40 degrees Celsius and 500 mA at 55 degrees Celsius, with 8 A per module at 40 degrees Celsius and 2 A at 55 degrees Celsius. Backplane current is 125 mA at 5V DC.
