Product Overview

The HIMA X-BLK 03 is a blank module designed for SB slots in HIMA systems. This module fills empty slots to maintain proper airflow and protection. The X-BLK 03 provides mechanical coverage for unused positions. Engineers use this blank module to prevent dust accumulation and accidental contact. The module supports redundant 24VDC connections for system flexibility. Its robust construction matches the quality of active HIMA modules.

Technical Specifications

Power Supply Characteristics

The HIMA X-BLK 03 operates on 24 VDC supply voltage. The acceptable range spans from -15% to +20% of nominal voltage. The ripple factor (rp) must stay below 5% for stable operation. The power supply unit requires safe insulation according to IEC 61131-2. This standard ensures proper isolation between primary and secondary circuits. The module accepts redundant operating voltage connections on L1+ and L2+ paths.

Current Ratings

The total maximum current through the X-BLK 03 reaches 63 A. An external fuse with maximum 63 A rating protects the circuit. HIMA recommends a line protection fuse for overcurrent protection. The module itself does not contain internal fuses. Users must provide external fusing according to system requirements.

Construction Materials

The backplane uses stainless steel for excellent corrosion resistance. This material provides high mechanical strength and durability. The mechanical attaching parts are made of aluminum for light weight. These materials ensure long service life in industrial environments. The construction matches the quality of standard HIMA SB series modules.

Environmental Limits

The HIMA X-BLK 03 operates from 0 °C to +60 °C ambient temperature. Store the module between -40 °C and +85 °C for long-term preservation. The humidity tolerance reaches 95% relative humidity maximum. This rating applies only to non-condensing conditions. Do not expose the module to dripping or splashing water. The type of protection is IP20 for basic finger protection. This means no protection against water ingress.

Physical Dimensions

The X-BLK 03 fits standard SB slots in HIMA racks. The module occupies one slot position. The compact design allows dense packing of active modules. The stainless steel backplate provides rigid mounting. The aluminum attaching parts allow secure fastening to the rack.

Installation Guide

Follow these steps to install the HIMA X-BLK 03 blank module. First, verify the slot position is unused and no active module is needed. Second, align the X-BLK 03 with the SB slot guide rails. Third, slide the module into the slot until the connectors engage.

Fourth, secure the module with the top and bottom retaining screws. Tighten to 0.5 N·m maximum. Fifth, connect the redundant 24VDC supplies to L1+ and L2+ terminals if power routing is required. Sixth, install an external 63A line protection fuse upstream of the module. Seventh, verify the operating temperature stays within 0°C to 60°C range. Eighth, ensure the IP20 protection is maintained by keeping the cabinet closed.

Frequently Asked Questions (FAQ)

1. What is the purpose of the HIMA X-BLK 03 blank module?
The X-BLK 03 fills empty SB slots in HIMA racks. It maintains proper airflow and cooling paths. It also prevents dust ingress and accidental contact with backplane connectors.

2. Does the X-BLK 03 require an external fuse?
Yes, you must install an external 63A line protection fuse upstream of the X-BLK 03. The module does not have internal fusing. This fuse protects the redundant power supply wiring.

3. What is the operating temperature range for the HIMA X-BLK 03?
The X-BLK 03 operates from 0 °C to +60 °C. Storage temperature ranges from -40 °C to +85 °C. Keep humidity below 95% non-condensing for reliable operation.

4. Can I use the X-BLK 03 in outdoor cabinets?
The IP20 protection rating means no water ingress protection. Use the X-BLK 03 only inside protected indoor cabinets. Outdoor use requires an additional weatherproof enclosure.

5. What materials are used in the HIMA X-BLK 03 construction?
The backplane uses stainless steel for strength and corrosion resistance. The mechanical attaching parts use aluminum for light weight. These materials provide long-term industrial durability.
