Frequently Asked Questions about 1756-OBV8S
Question: What is the 1756-OBV8S module used for?
Date Update:28/05/2025
Answer:

The 1756-OBV8S is an 8-point digital safety output module designed for use in ControlLogix systems. It provides sourcing and bipolar DC outputs for safety-critical applications, supporting Safety Integrity Level (SIL) 3 and Performance Level (PL) e, Category 4, as defined in IEC 61508 and ISO 13849-1 standards.

Question: What are the key specifications of the 1756-OBV8S module?
Date Update:28/05/2025
Answer:
  • Output Type: Digital sourcing/bipolar
  • Number of Outputs: 8
  • Voltage Range: 10–30V DC
  • Maximum Output Current per Channel: 0.5 A
  • Safety Ratings: SIL 3, PL e, Category 4
  • Module Type: Non-isolated
  • Compatible Chassis: 1756 ControlLogix Series C
  • Removable Terminal Blocks (RTBs): 1756-TBNHS or 1756-TBSHS (sold separately)
Question: How does the 1756-OBV8S differ from standard output modules?
Date Update:28/05/2025
Answer:

The 1756-OBV8S is specifically designed for safety applications. It includes features such as point-level output fault states, field-side diagnostics, and compliance with stringent safety standards (SIL 3, PL e). Unlike standard output modules, it ensures reliable operation in safety-critical systems and supports safety-rated control of actuators and other devices.

Question: What are the wiring considerations for the 1756-OBV8S module?
Date Update:28/05/2025
Answer:

Each output channel of the 1756-OBV8S can be configured in sourcing or bipolar mode. For proper operation, it's essential to use the specified RTBs (1756-TBNHS or 1756-TBSHS) and ensure that the connected power supply complies with SELV or PELV standards. Additionally, due to higher internal power dissipation, the module should not be installed adjacent to controller or communication modules to prevent overheating.

Question: Is the 1756-OBV8S compatible with Studio 5000 and GuardLogix controllers?
Date Update:28/05/2025
Answer:

Yes, the 1756-OBV8S is fully compatible with Studio 5000 Logix Designer software and is designed to operate with GuardLogix 5580 controllers. Proper configuration within Studio 5000 is necessary to integrate the module into a safety control system, ensuring that safety functions are correctly implemented and validated.
