HIMA X-DO 32 01 Product Specification
1. Product Overview
The HIMA X-DO 32 01 is a safety-related digital output module specifically designed for HIMA’s HIQuad X and HIMax safety instrumented systems (SIS). As a critical component in industrial safety loops, it converts safety-critical digital control signals from the central controller into reliable output signals to drive field actuators—such as emergency shutdown valves (ESVs), isolation valves, and alarm sirens. Widely applied in high-risk industries including oil & gas, petrochemical, chemical processing, and nuclear power, this module ensures deterministic execution of safety functions, preventing hazardous events and protecting personnel, equipment, and the environment.
Compliant with international safety standards such as IEC 61508 (SIL 3) and IEC 61511, the X-DO 32 01 features a fault-tolerant dual-channel design and strict diagnostic mechanisms. It maintains high reliability and availability in harsh industrial environments, meeting the most stringent safety requirements of process industries.

3. Key Features
3.1 SIL 3 Safety Compliance
The X-DO 32 01 is certified for SIL 3 operation, with a dual-channel redundant design and hardware fault tolerance (HFT = 1) that ensures safety functions remain available even if a single channel fails. Its high diagnostic coverage (≥99%) enables timely detection of faults, preventing dangerous failures and meeting the safety requirements of high-risk processes.
3.2 High Reliability & Deterministic Performance
With a response time of ≤1 ms, the module ensures immediate execution of safety commands—critical for emergency scenarios like pressure relief or shutdown. The redundant power input and robust component selection minimize unplanned downtime, maintaining high system availability for continuous process operations.
3.3 Flexible Channel Configuration
The 32 independent output channels can be individually configured via HIMA’s HIMatrix Engineering Studio software, supporting functions such as “safe on” or “safe off” states. This flexibility allows the module to adapt to diverse safety loops, from simple alarm activation to complex valve control sequences.
3.4 Seamless SIS Integration
Optimized for HIMA’s HIQuad X and HIMax SIS, the module supports plug-and-play installation and automatic configuration via the system backplane. It integrates with HIMA’s safety control software for centralized monitoring, fault diagnosis, and maintenance, simplifying the design and operation of safety instrumented systems.
