HIMA B9302 997009302 8-Channel Digital Output Module

The HIMA B9302, also designated as EABT3 997009302, is a safety-related digital output module designed for integration with HIMA F35 compact safety controllers. This module provides eight independent output channels certified for safety applications up to SIL 3 according to IEC 61508 and IEC 61511 standards. It serves as a critical component for actuating final elements in emergency shutdown systems, burner management, and other high-integrity applications.

Output Channel Specifications

Safety Function and Fault Response

The B9302 module implements a de-energized to trip safety principle, ensuring that any detected fault results in a safe output state. Each output channel is continuously monitored for overload conditions. When an overload is detected, the affected channel or all channels are switched off to prevent damage. Once the overload condition is removed, the outputs automatically resume normal operation without requiring manual intervention.

Diagnostic and Monitoring Capabilities

Comprehensive diagnostic features enable reliable operation in safety-critical environments. The module provides:

• Individual LED indicators for real-time status of each output channel

• Short-circuit detection with fault signaling to the controller

• Overload detection with automatic thermal protection

• External wire monitoring via analog input integration

Line monitoring for digital outputs can be implemented using analog inputs to detect open-circuit and short-circuit conditions. This configuration achieves SIL 3 compliance when properly implemented with external monitoring circuitry.

Integration with HIMA F35 Systems

The B9302 is designed as an integral component of the HIMA F35 safety controller family. The F35 controller is a compact system housed in a metal enclosure that supports up to 24 digital inputs, 8 digital outputs, 2 counters, and 8 analog inputs. The controller variants are available for both SILworX and ELOP II Factory engineering platforms. The device is suitable for mounting in Ex-zone 2 hazardous area applications and has been certified by TÜV for safety-related applications up to SIL 3, Category 4 per EN 954-1, and PL e per EN ISO 13849-1.

Environmental and Operational Conditions

The module operates reliably across a wide range of industrial conditions. It is designed to withstand ambient temperatures up to 60°C while maintaining full output current capacity. The module incorporates robust electromagnetic compatibility features to ensure reliable operation in electrically noisy industrial environments.

Applications

Typical applications for the HIMA B9302 output module include:

• Emergency shutdown systems for oil and gas facilities

• Burner management and flame safeguard systems

• High-integrity pressure protection systems

• Chemical process safety interlocks

• Turbine and compressor control systems
