Allen-Bradley 1715-OB8DE Digital Output Module

Product Description

The Allen-Bradley (AB) 1715-OB8DE is a high-reliability digital output module belonging to the 1715 I/O system family, designed for seamless integration with Rockwell Automation's ControlLogix, CompactLogix, and Micro800 PLC platforms. Engineered for hazardous and harsh industrial environments, this module features intrinsic safety (IS) certification, robust channel-to-channel galvanic isolation, and enhanced electromagnetic interference (EMI) resistance, ensuring stable operation in explosive atmospheres (Zone 2/22) and extreme temperature/humidity conditions. Its compact, DIN rail-mount design optimizes control cabinet space, while plug-and-play connectivity with the 1715 I/O backplane simplifies installation, commissioning, and replacement. The 1715-OB8DE delivers precise, fast-switching digital output performance, making it an ideal solution for discrete control applications in process and manufacturing industries requiring compliance with global safety standards.

Key Functions

The core function of the 1715-OB8DE module is to convert digital control signals from Rockwell Automation PLCs into isolated 24 V DC output signals to drive field actuators such as solenoid valves, relays, contactors, and indicator lights in hazardous environments. It features 8 independent output channels with configurable sink/source operation, built-in short-circuit and overcurrent protection to safeguard both the module and connected devices from electrical damage. The module provides real-time diagnostic capabilities via Rockwell's RSLogix/Studio 5000 software, enabling monitoring of channel status, detection of open circuits/short circuits, and generation of diagnostic alarms for predictive maintenance. It supports hot-swap operation to minimize system downtime during module replacement, and offers deterministic output response times (≤1 ms) to meet the strict timing requirements of high-speed discrete control processes. Additionally, it complies with intrinsic safety standards (ATEX/IECEx) for safe operation in explosive atmospheres, eliminating the need for external safety barriers in Zone 2/22 applications.

Application Scenarios

The Allen-Bradley 1715-OB8DE digital output module is widely deployed in hazardous industrial environments across multiple sectors. In oil and gas upstream/midstream operations, it controls emergency shutdown (ESD) valves, pipeline isolation valves, and wellhead control actuators in Zone 2 hazardous areas. For chemical and petrochemical plants, it drives batch process valves, mixer motors, and safety interlock devices in explosive atmospheres containing flammable gases/vapors. In pharmaceutical manufacturing, it controls clean room equipment, dosing pumps, and packaging machinery in Zone 22 dust hazardous areas while complying with GMP standards. It is also ideal for food & beverage processing plants for controlling filling machine actuators, conveyor systems, and temperature control valves in potentially explosive environments (e.g., grain silos, sugar processing). Additionally, the module is used in mining operations for controlling ventilation fans and conveyor systems in underground hazardous areas, in power generation facilities for driving auxiliary equipment in turbine enclosures, and in automotive manufacturing for controlling robotic grippers and assembly station actuators in paint shop hazardous zones.
