The XYCOM 9475 series is a digital output module designed for industrial on-site safety and control. Compliant with IECEx/ATEX explosion-proof standards, it can be used in Zone 1, Zone 2, and other safety-classified areas. Available in 4-channel or 8-channel configurations, the module supports Ex i (intrinsically safe) outputs and features a “Plant STOP” function, enabling rapid shutdown of load power during emergency stops.
Key Specifications
- Open-circuit voltage: 17.9 V (Model 12)
- Rated operating current: 11.3 V/40 mA (Model 12)
- Output internal resistance: 170 Ω (Model 12)
- Operating voltage: 24 V DC (18–30 V operating range)
- Protection class: IP65, meeting IECEx/ATEX explosion-proof requirements
- Weight: Approximately 0.275 kg
- Dimensions: Approximately 150 mm × 100 mm × 50 mm
Product Features
- Explosion-proof safety: Complies with IECEx/ATEX standards for reliable operation in hazardous environments.
- Multi-channel design: Offered in 4-channel or 8-channel versions to meet I/O requirements of different systems.
- Plant STOP function: Immediately cuts off all outputs during emergency stops to enhance on-site safety.
- Modular structure: Adopts a pluggable design with hot-swap support for quick on-site replacement and maintenance.
- Low power consumption: Internal circuits use low-power chips to reduce energy consumption and heat generation.
- Wide operating temperature range: -20 °C to 60 °C, suitable for harsh industrial on-site environments.
Structure and Composition
- Housing: Metal protective casing with dust and water resistance (IP65).
- Power module: 24 V DC input with internal voltage stabilization circuit.
- Output channels: Each channel is equipped with an Ex i relay, current-limiting resistor, and protection diode.
- Connection terminals: Screw terminal block supporting shielded cable connection.
- Indicators: Status LED indicators for power supply, faults, and output status.
- Mounting bracket: Compatible with industrial chassis standards such as VME and PXI.
Typical Application Fields
- Petrochemical industry: Safety control of valves, pumps, heaters, etc., in hazardous areas.
- Energy and power: Emergency shutdown circuits in power plants and substations.
- Metallurgy and heavy industry: Machine safety interlocking in high-temperature and high-dust environments.
- Automated production lines: Safety output points for PLC and DCS systems.
- Transportation and rail: Explosion-proof interfaces for train signals and turnout control.
Installation and Maintenance Guidelines
- Before installation: Cut off the main power supply and confirm the chassis is fixed in the explosion-proof area.
- Wiring: Use shielded cables that meet explosion-proof standards, fasten terminals with screws to ensure no looseness.
- Plugging/unplugging: The module supports hot-swapping; align with the card slot and press gently until fully seated.
- Inspection: After installation, check the integrity of indicators and gaskets to ensure the protection class is not compromised.
- Regular maintenance: Inspect terminal tightness and internal heatsink dust accumulation every 6 months, and clean if necessary.
- Troubleshooting: Read the module’s self-test status via PLC/HMI. For Ex i output abnormalities, first check the power supply and wiring, then replace the relay of the corresponding channel.
