HIMA X-DI-32-01

HIMA X-DI-32-01 is a 32-channel digital input module launched by HIMA (Germany) for safety-related Programmable Electronic Systems (PES). It is suitable for industrial automation scenarios with safety levels of SIL 3 (IEC 61508/61511) and Cat. 4 (EN 954-1). The module can be inserted into any slot of the base (except the system bus slot), is powered by a 24 V DC power supply, supports high-speed (< 1 ms) signal acquisition, and provides channel-level diagnostic functions.

Main Technical Parameters

• Number of Channels: 32 independent digital inputs
• Input Type: Dry contact (relay) input, compatible with 24 V DC signals
• Supply Voltage: 24 V DC (±15 %)
• Response Time: < 1 ms (typical value)
• Diagnostic Functions: Open/short circuit detection, channel-level self-test, abnormal alarm
• Safety Level: SIL 3 (IEC 61508/61511), Cat. 4 (EN 954-1), PL e (EN ISO 13849-1)
• Operating Temperature: -25 °C ~ +70 °C (compliant with IEC 60204-1)
• Installation Method: DIN rail mounting, fixed in the cabinet in line with IEC 60204-1 standard

Product Features

• High Reliability: Adopts high-quality electronic components and strict manufacturing processes, enabling long-term stable operation in harsh industrial environments.
• Safety Certification: Has passed TÜV certification, meets safety standards such as SIL 3 and Cat. 4, and is suitable for Safety Instrumented Systems (SIS).
• Modular Design: Plug-and-play structure, facilitating quick replacement and expansion, and supporting seamless combination with other HIMA safety modules.
• Channel-Level Diagnostics: Real-time monitoring of faults such as open circuits and short circuits of each input, ensuring the system enters a safe state in case of abnormalities.
• Fast Response: The response time of < 1 ms meets high-speed safety requirements such as Emergency Shutdown (ESD).

Structure and Composition

• Module Body: 32 dry contact input terminals, power supply terminals, and diagnostic indicator lights.
• Communication Interface: Compatible with industrial buses such as PROFIBUS and PROFINET, used for communication with HIMA safety controllers.
• Power Module: Internal voltage stabilization circuit to ensure the stability of 24 V DC power supply.
• Mounting Bracket: Buckle structure conforming to DIN rail standards, facilitating fixation in cabinets compliant with IEC 60204-1 specifications.

Typical Application Fields

• Chemical, Petroleum, Natural Gas Industry: Safety interlocking, emergency shutdown, process monitoring.
• Electric Power, Power Plants: Unit protection, valve control, relay protection.
• Metallurgy, Iron and Steel Industry: Safety monitoring of high-temperature furnaces, interlocking of conveying systems.
• Pharmaceutical, Food Industry: Safety control in clean areas, monitoring of key process parameters.
• Other High-Risk Industries: Any process control system that needs to achieve SIL 3 level safety integrity.
