As a trusted supplier in the industrial automation sector, Rossonix Co., Limited brings you the reliable Allen-Bradley 1756-OBV8S Digital DC Safety Output Module. Established in 2011 and backed by ISO9001 quality management, we understand the critical need for robust safety components in modern manufacturing. This module is engineered to provide secure, isolated control outputs for your most vital machine safety functions, helping you protect personnel, equipment, and processes.
Integrating this module into your ControlLogix system enhances your safety architecture with dedicated, high-reliability channels. It is designed for applications where standard outputs are insufficient, offering the integrity required for emergency stops, guard door monitoring, or safety interlock systems. Let's explore the features that make this module a cornerstone for safe automation.
Core Features & Technical Specifications:
Dedicated Safety Design: The 1756-OBV8S is specifically configured for safety applications, providing 8 independent DC output channels. Each channel is designed with isolation and monitoring to ensure a single fault does not compromise the entire safety function.
ControlLogix Platform Integration: This module seamlessly integrates into the Allen-Bradley 1756 ControlLogix chassis. It communicates via the backplane, allowing tight coordination with other ControlLogix processors and I/O modules for unified control and safety logic.
High Reliability Outputs: The outputs are rated for demanding industrial environments. They are suitable for controlling safety devices like solenoid locks, safety relays, and indicator lamps with consistent performance.
Diagnostic Capabilities: The module provides status feedback and diagnostic information to the controller, enabling proactive maintenance and quick fault identification, which is crucial for maintaining safety system integrity.
Compact & Efficient: Occupying a single slot in the ControlLogix chassis, it delivers eight safety outputs efficiently, optimizing cabinet space and system layout.
Key Parameters:

Frequently Asked Questions (FAQ)
-
Q: What is the main purpose of the 1756-OBV8S module?
A: Its primary purpose is to provide dedicated, safety-rated digital DC outputs within a ControlLogix control system. It is used for critical functions like emergency stops, safety door monitoring, and other applications where high reliability and fault tolerance are required.
-
Q: Can this module be used in a standard (non-safety) ControlLogix application?
A: While it is specifically designed for safety applications, its outputs could be used for standard control. However, its value lies in its safety-oriented design with features like isolation and diagnostics, which are best utilized in safety-critical circuits.
-
Q: How many devices can I control with one 1756-OBV8S module?
A: The module provides 8 independent output channels. Each channel can typically control one safety device, such as a solenoid or relay coil. The exact number depends on the current rating and the specific device connected.
-
Q: What is required to configure and program this module?
A: Configuration and programming are done using Rockwell Automation's software (such as RSLogix 5000 or Studio 5000) for the ControlLogix platform. The module is recognized as a safety I/O device within the software environment.
-
Q: Does this module offer diagnostic feedback?
A: Yes, it provides status and diagnostic information back to the ControlLogix controller via the chassis backplane. This allows the control system to monitor the health of the safety outputs and log any faults.
-
Q: Is special wiring required for the safety outputs?
A: Wiring should follow safety principles and local electrical codes. It typically involves using appropriately rated cables and ensuring proper isolation from other circuits. Detailed wiring guidelines are available in the module's technical documentation.
-
Q: Can I mix safety and standard I/O modules in the same ControlLogix chassis?
A: Yes, the ControlLogix platform allows mixing of different module types, including standard I/O, safety I/O, and communication modules, within the same chassis. This provides flexible system design.
-
Q: What is the typical delivery time for this module?
A: Delivery time depends on stock availability and destination. As a supplier with multiple shipment ports (Shenzhen, Hong Kong, Europe), Rossonix can often provide efficient shipping options to various global markets.
