1715-OB8DE Digital Output Module | Allen-Bradley

Description

The Allen-Bradley 1715-OB8DE Digital Output Module is an 8-point safety digital output unit belonging to the 1715 redundant I/O system, engineered specifically for harsh industrial environments. It features 8 independent safety digital output channels with transistor output type, operating on 24V DC (with a working voltage range of 19.2V DC to 28.8V DC). Each channel supports a maximum rated current of 2A, making it suitable for driving mid-load industrial components. This module meets high safety standards, including SIL3 (per IEC 61508) and PL e (per ISO 13849-1), ensuring reliable performance in safety-critical applications. It has a fast response time of ≤10ms, enabling quick and precise control signals. Key functional features include configurable source or sink operation for each channel, a built-in diagnostic system for proactive monitoring, and a removable screw terminal block for secure and convenient backplane communication via the GuardPLC protocol. Common application scenarios include controlling motors, valves, and other actuators, transmitting alarm and event signals, and integrating with PLCs and other control systems for data collection and recording.
