Phoenix SACB Series Industrial Bus Distribution & Connection Modules Selection Guide

Opening: Modular Distribution Solutions for Industrial Signal & Power Branching

The Phoenix SACB series is a portfolio of industrial-grade bus distribution modules and connection terminals designed for centralized branching of industrial signal/power lines in factory automation systems. Covering 4-channel/8-channel distribution, fuse protection, M23 interface compatibility, and diverse cable materials (PUR/HPUR), these modules feature modular design, IP65/IP67 protection (when mated), and integrated fuse diagnosis functions. Widely used in robotic workstations, production line sensor/actuator wiring, and cabinet-internal signal distribution, they realize efficient, safe, and scalable industrial bus line management in harsh environments.

I. Core Advantages of the SACB Series

1. Multi-scenario distribution capability:
   • Supports 4-channel (4Q/4P/4/T) and 8-channel (4/8) signal/power branching, adapting to small-to-medium scale device connection needs;
   • Integrated 8-way fuse protection (4/T-L-8FUSE series) for overcurrent protection of field devices;
   • M23 interface variants for compatibility with heavy-duty circular connector systems.
2. Diverse cable & interface compatibility:
   • Cable materials: Standard PUR (polyurethane) for general scenarios, HPUR (high-flexibility PUR) for robotic/moving device connections;
   • Cable lengths: 5.0m/10.0m for field/cabinet wiring, meeting different installation distance requirements;
   • Interfaces: SC (signal contact), M23 heavy-duty interface, and fuse terminals (PT/QO/GG) for protection customization.
3. Industrial-grade reliability:
   • IP65/IP67 protection (when mated) for dust/water resistance, suitable for workshop floor and outdoor field scenarios;
   • High-flexibility HPUR cables with bending resistance (≥10 million bending cycles), ideal for robotic arm moving parts;
   • Fuse diagnosis function (DIAG) for real-time fault monitoring of branch circuits, reducing maintenance time.
4. Modular & scalable design:
   • DIN rail or panel-mounted installation, compatible with Phoenix control cabinet infrastructure;
   • Replaceable fuse cartridges for quick maintenance without rewiring;
   • Multiple coding variants (SCO/P/QO) for anti-misconnection and system compatibility.

IV. 3-Step Quick Selection Technique

Step 1: Select Module Type Based on Functional Requirement

• Branch circuit overcurrent protection: Choose 4/T-L-8FUSE series; select DIAG variant (1411048) for fault monitoring, standard variant (1413929) for basic protection.
• Mixed signal/power distribution: Opt for 4Q/4P-L-SC (1662939) for 4-signal+4-power dual-channel branching.
• M23 device connection: Pick M23 interface variants (1692747/1692802/1692682/1692417); 180° angle for straight device connection, standard angle for general scenarios.
• General 4-to-8 distribution: Select 4/8 series basic modules (1692035) for non-fuse scenarios, C/PT/GG fuse variants for protection needs.

Step 2: Match Cable Material & Length to Installation Scenario

• Robotic moving parts/moving devices: Choose HPUR high-flex cable (1695906/1517262/1517275) for bending resistance (≥10 million cycles).
• Fixed cabinet/field wiring: Select standard PUR cable (1516988/1517107/1516991) for cost-effective wear resistance.
• Short-distance (≤5m) connection: Pick 5.0m cable variants (all 5.0PUR/HPUR models).
• Long-distance (5-10m) connection: Choose 10.0m cable variants (all 10.0PUR/HPUR models).

Step 3: Choose Coding/Protection for System Compatibility

• Standard industrial systems: Select SCO coding (most models) for IP67 protection and universal compatibility.
• High-reliability/critical scenarios: Opt for SCO P enhanced coding (1452819/1412058/1452602) for anti-misconnection and higher protection.
• Legacy equipment: Pick QO coding (1156005/1175448) for matching legacy control systems.
• CT/AXL control systems: Choose CT/AXL suffix models (1411048/1413929) for seamless system integration.

VI. Selection Pitfall Avoidance Guide

1. Cable material mismatch: Robotic moving parts using standard PUR cables → Select HPUR high-flex variants (1695906) to avoid cable fatigue and breakage during frequent movement.
2. Fuse type error: Precision instruments using GG general fuses → Choose PT fast-break fuses (1412058) to achieve quick overcurrent protection and prevent device damage.
3. Interface incompatibility: M23 devices using SC interface modules → Pick M23 interface variants (1692747) to ensure mechanical and electrical compatibility.
4. Diagnosis function neglect: Unattended workshops using non-DIAG fuse modules → Select 1411048 (with DIAG) for real-time fault alarm, reducing manual maintenance costs.
5. Coding mismatch: Legacy QO systems using SCO modules → Choose QO coding variants (1156005/1175448) to avoid connection failure and protocol incompatibility.
