Description
- Model: HIMA Z7138
- Part Number: 933330100-5
- Brand: HIMA (Germany)
- Series: HIQuad System
- Core Function: Passive termination and wiring interface for HIMA safety-related I/O modules.
- Product Type: Terminal Module / Connection Board
- Key Specs: Multi-pole system connector DIN Rail Mount Optimized for F8621/F8627 modules
Key Technical Specifications
- Compatibility: Specifically designed for interfacing with HIMA HIQuad modules, such as the F8621 (Input) or F8627 (Output) series.
- Mounting: Standard 35 mm DIN rail (horizontal or vertical).
- Wiring Interface: Features high-density screw or spring-clamp terminals for field-side wiring and a specialized system connector for the module-side cable.
- Voltage Rating: 24 V DC (Standard logic and field supply for safety loops).
- Configuration: Supports full channel density of the mated module (typically 8 to 16 channels).
- Safety Level: Suitable for SIL 3 applications when integrated into a certified HIMA safety system.
- Isolation: Provides clear physical and electrical separation between field-level wiring and sensitive rack electronics.

Installation & Configuration Guide
Phase 1: Preparation (Pre-Installation)
Estimated time: 10 minutes
⚠️ Safety Warning:
- Safety Loop Integrity: The Z7138 is a critical path for safety signals. Ensure the process is in a safe state or that the relevant loops are effectively bypassed.
- Power Down: While passive, it is best practice to de-energize the I/O power before connecting or disconnecting the system cable to avoid transient spikes.
- Cable Check: Inspect the system cable (BV series) for any pin damage or oxidation before mating it with the Z7138.
Required Items:
- HIMA system cable (e.g., BV 7032).
- Insulated screwdriver set.
- Loop drawing/wiring schedule.
Phase 2: Mounting & Field Wiring
Estimated time: 15 minutes
Step 1: Rail Placement Secure the Z7138 to the DIN rail. Ensure there is enough space to allow the system cable to bend naturally without straining the connector.
Step 2: Signal Termination Connect the field wires to the labeled terminals.
- Tip: For SIL 3 loops, ensure that the cable shielding is correctly grounded at the cabinet entry or terminal block as per HIMA grounding guidelines to prevent EMI-induced faults.
Step 3: Cable Connection Plug the multi-pin system cable into the Z7138 connector. Tighten the securing screws/clips to ensure the cable remains seated under vibration.
Phase 3: Commissioning & Testing
Estimated time: 10 minutes
- Continuity Check: Before powering up, verify there are no short circuits between the 24V supply and signal channels.
- System Sync: Energize the HIMA rack. The I/O module should show a green “RUN” or “OK” LED if the Z7138 and its wiring are correctly detected.
- Loop Verification: Use the SILworX or ELOP II diagnostic tools to monitor the channel states while simulating a field input.
Customer Cases & Industry Applications
Case 1: Power Plant Burner Management (BMS) A large power utility in Southeast Asia required a rapid replacement for a damaged Z7138 board after a cabinet cooling failure led to heat damage on the plastic terminals. By sourcing a New Surplus unit from our stock, the plant avoided a prolonged outage of the boiler system, restoring the BMS safety integrity in under 72 hours.
Case 2: Chemical Processing Safety Upgrade A chemical plant was expanding its reactor safety loops and needed consistent termination hardware to match its existing HIQuad architecture. We provided four 933330100-5 modules. Since these were “New-in-Box” surplus, they passed the plant’s internal QA audit with ease, offering a cost-effective alternative to ordering through long-lead OEM channels.
Frequently Asked Questions (FAQ)
Q: Is the Z7138 a “smart” module? A: No. The Z7138 is a passive termination board. It does not contain a processor. It acts as a bridge between the flexible field wiring and the high-density system cables that plug into the HIMA rack.
Q: Does the -5 in the part number signify a specific revision? A: Yes, the suffix often denotes a hardware revision or a specific terminal block type (e.g., screw terminals vs. spring terminals). The 933330100-5 is a standard, widely compatible version.
Q: Can I use this for both inputs and outputs? A: Generally, yes. The Z7138 is designed to handle the wiring for both digital inputs (like the F8621) and digital outputs (like the F8627), provided the pin-out of the system cable matches the application.
Q: Why is “New Surplus” preferred over “Refurbished” for HIMA? A: In safety systems (SIS), reliability is everything. A refurbished board may have hidden stress on the copper traces. “New Surplus” boards have zero hours of operation and haven’t been subjected to the thermal cycles of a running plant, ensuring the highest possible reliability.
Q: Does it come with the plastic housing? A: Yes, our Z7138 modules come complete with the DIN-rail mounting base and the protective terminal housing as shown in original HIMA specifications.
