Allen-Bradley 1734-OBV2S Safety Output Module

The Allen-Bradley 1734-OBV2S POINT Guard I/O safety digital output module provides four bipolar safety outputs across two output pairs for CIP Safety networks, enabling safe control of actuators and interlocks from a POINT Guard I/O system. It operates from a 24V DC field supply, with each bipolar output pair rated up to 1.25 A at 40°C (derating to 0.5 A at 55°C) and an aggregate module current of 2 A at 40°C (0.8 A at 55°C) across both pairs. Key electrical specs include an on-state voltage drop of about 0.33 V per bipolar pair, leakage current up to 1.0 mA, electronic short-circuit detection, and a safety test pulse width of 475 μs with a pulse period of 575 ms. Additional safety-related characteristics cover a sensor power supply current rating of up to 0.7 A per point at 40°C (0.3 A per point at 55°C) and a maximum field capacitance of 950 nF per output, supporting reliable operation in safety-critical applications such as interlocks, guards, and emergency-stop circuits within POINT Guard I/O configurations.
