Features:
- 36-pin spring-clamp terminal design ensuring stable and vibration-resistant field wiring connections
- Modular removable structure enabling easy installation, replacement, and system maintenance
- Designed for ControlLogix I/O integration with defined electrical and environmental performance limits
The Allen-Bradley 1756-TBS6H is widely used in ControlLogix systems to provide a structured and reliable interface between field wiring and I/O modules. It enables secure termination of plant wiring through a 36-pin spring-clamp arrangement, supporting organized signal distribution across automation systems. The 1756-TBS6H is not shipped with I/O modules, allowing users to select the appropriate terminal block based on wiring requirements. This flexibility makes it suitable for customized industrial control cabinet designs. It plays an important role in ensuring stable signal connectivity in complex control architectures.
In operation, the 1756-TBS6H provides a mechanical and electrical interface that supports consistent signal transmission between field devices and controller modules. The spring-clamp mechanism maintains firm contact pressure, reducing the need for periodic maintenance. Its compatibility with 20 AWG wiring ensures alignment with standard industrial wiring practices. The 1756-TBS6H integrates directly into the front of ControlLogix modules, forming a compact and efficient connection system. This structure supports reliable long-term operation in industrial environments.
From a system design perspective, the Allen-Bradley 1756-TBS6H is part of a broader wiring ecosystem that includes interface modules and prewired cable assemblies. Depending on application needs, users may select extended housing or alternative RTB types for larger wire sizes or safety-certified configurations. The module supports stable electrical performance under defined current and temperature conditions. The 1756-TBS6H therefore contributes to scalable and maintainable I/O system architecture. Its design supports efficient installation, serviceability, and system organization in modern automation environments.
The 1756-TBS6H Allen-Bradley 36 Pin Spring Terminal Block may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Slide-in latch locking: The terminal block is equipped with dedicated plastic latching panels on the top and bottom. Aligning with the front of the module and pushing it in, it self-locks, ensuring a tight engagement with the I/O card even under heavy loads and vibrations.
- Tool-free quick wiring: Utilizing a high-sensitivity spring-clamp design, bare wires or wires with pin terminals can be reliably crimped simply by inserting them directly, eliminating the need for individual screwdriver tightening.
- Physical error-proof pin positioning: Includes a dedicated mechanical keying feature, allowing engineers to hard-code the terminal block and specific I/O modules for matching, preventing accidental insertion into the wrong card model during subsequent maintenance.
- Built-in integrated cable tie slot: The terminal block's bottom structure features an integrated plastic housing and cable tie fixing points, allowing 36 wires to be organized into a bundle and securely bound, preventing cables from being pulled out by gravity during long-term operation.
- High-Density Digital I/O Wiring: Provides original equipment manufacturer (OEM) physical interfaces specifically for high-density cards such as the 1756-IB32 (32-point DC input) or 1756-OB32 (32-point DC output), perfectly accommodating 32 signal lines.
- High-Vibration Industrial Deployment: Widely used in automated scenarios with continuous physical vibration and mechanical reciprocating motion (such as forging presses and mining crushing equipment control cabinets), utilizing spring-loaded connections to prevent contact loosening.
- Mass Production of Standard Control Cabinets: On the large-scale assembly lines of control cabinet OEM manufacturers, spring modules significantly shorten wiring time, enabling standardized mass production of the system in conjunction with pre-wired cables.
- Optimized Wiring in Narrow Cabinet Spaces: In space-constrained HMI control boxes with inconvenient operating angles, this screwless wiring accessory greatly improves the comfort of maintenance personnel performing wiring operations in cramped environments.
- Reduced On-Site Labor Costs: Thanks to the plug-and-play nature of the spring-clamped terminals, compared to traditional screw terminals (1756-TBNH), it can save over 50% of manual installation time for high-density wiring with 36 pins per cabinet.
- Maintenance-Free, Vibration-Resistant, and Anti-Loosening: The internal spring constant pressure mechanism automatically compensates for wire deformation caused by environmental thermal expansion and contraction, completely eliminating the need for periodic manual tightening in long-term factory high-frequency vibration environments.
- Rapid Online Spare Part Replacement: When replacing a damaged I/O module, simply loosen the physical latch to completely remove the terminal block. A new module can be seamlessly installed in seconds without disassembling any on-site physical wiring.
- Clear Multi-Channel Wire Numbering: The terminal cover includes a customizable wiring label area, allowing engineers to directly print or write the corresponding variable names for terminals 1 to 36, significantly improving subsequent troubleshooting efficiency.
