Allen-Bradley 5094-IB16S FLEX 5000 Safety Input Module

Configured for safety-rated discrete signal acquisition in EtherNet/IP distributed I/O systems, the Allen-Bradley 5094-IB16S (5094-IB16S FLEX 5000 Safety Input Module) provides direct monitoring of field safety devices through sixteen sinking input channels. The module interfaces with the FLEX 5000 platform via a 15 VDC backplane and supports safety-focused machine and process control architectures requiring diagnostic monitoring and fault detection.

Hardware Specifications

EtherNet/IP Deterministic Network Integration

The 5094-IB16S operates within the FLEX 5000 distributed I/O architecture and exchanges input status data through the platform backplane to the EtherNet/IP adapter. The 15 VDC backplane interface supports high-speed communication between the module and associated FLEX 5000 network infrastructure.

Mechanical and electronic keying mechanisms help prevent installation of incorrect module types within an I/O assembly. The platform architecture supports scalable I/O deployment while maintaining deterministic communication characteristics expected in Logix-based control systems.

Frequently Asked Questions

Q: Are the input channels individually isolated?
A: No. The specifications indicate system-to-field isolation of 250 V continuous, but no isolation exists between individual input channels or between SA power and input ports.

Q: Which terminal assemblies are supported?
A: The module supports compatible FLEX 5000 mounting base and removable terminal base combinations including 5094-MB with 5094-RTB3I or 5094-RTB3IS, and 5094-MBXT with 5094-RTB3IXT or 5094-RTB3ISXT.

Q: Does the module include onboard status indication?
A: Yes. The module provides one module status indicator, one sensor actuator power indicator, and sixteen channel status indicators for diagnostics and commissioning.

Field Installation Guidelines

• Install the module on the appropriate FLEX 5000 mounting base before applying field power.

• Verify that the sensor actuator supply remains within the specified 18-32 VDC operating range.

• Use conductor routing practices appropriate for Category 2 signal and power circuits.

• Separate field input wiring from high-energy motor and power conductors.

• Ensure all copper conductors meet the specified wire gauge and temperature ratings.

• Confirm terminal base keying before inserting the module into service.

• Mount the assembly within a protective enclosure suitable for the installation environment since the module utilizes an open-style housing.

• Perform channel verification and input status testing following startup and maintenance activities.
