Independent Output Channels

This module features eight independent solid-state output channels for flexible control. Each channel provides 2.0 A of output current for driving field devices. The outputs support both capacitive and inductive loads without derating. This versatility enables connection to various safety system actuators.

Comprehensive Diagnostics

Built-in diagnostics detect open-wire conditions and short-circuit faults on each channel. The module reports diagnostics status to the Safety Manager for maintenance purposes. Test pulses verify output integrity without activating connected devices. Consequently, this module ensures reliable performance in safety-critical applications.

Fast Response Performance

The module delivers a maximum response time of 10 milliseconds for critical safety functions. This rapid switching ensures timely system reaction to emergency conditions. The solid-state design eliminates contact bounce and mechanical wear. Furthermore, the module maintains consistent switching performance across the entire temperature range.

Robust Isolation and Protection

1500 VAC isolation protects the module from transient surges and ground loops. The output circuits withstand short-circuit conditions without internal damage. Overcurrent protection prevents module damage from wiring errors or field faults. Therefore, this module provides long-term reliability in demanding safety applications.

Safety System Integration

This module integrates directly with Honeywell Safety Manager and Experion PKS systems. The standardized interface simplifies engineering, installation, and commissioning. Each channel includes individual LED indicators for immediate output status visualization. Additionally, you can replace modules without powering down the system.

Safety Certification

This module meets IEC 61508 SIL 3 requirements for safety instrumented systems. It also complies with ISO 13849 for machinery safety applications. The module carries TÜV Rheinland certification for functional safety. Consequently, this output module is a trusted choice for critical safety functions worldwide.
