Schneider Modicon Quantum TSXSCPCM4030 Premium RS-422/485 Tap Link Cable

Schneider Electric TSXSCPCM4030 Modicon Premium RS-422/485 Tap Link Cable — 3M, Isolated, Modbus Character Mode

The TSXSCPCM4030 is a 3-meter isolated RS-422/RS-485 tap link cable for Schneider Electric's Modicon Premium automation platform. It connects TSX SCP 114 PCMCIA communication cards (installed in Premium/Micro PLCs) to Modbus serial networks via a passive junction box (TSX SCA 50). The cable features flying leads on the field side for flexible wiring and provides electrical isolation between the PLC and the field bus, protecting against ground loops and electrical noise in industrial environments.

Architecture & Functionality

• PCMCIA Card Interface: TSX SCP 114 plugs into the PCMCIA slot of TSX Premium or TSX Micro PLCs, providing an isolated RS-485 serial port
• Tap Link Connection: TSXSCPCM4030 cable connects the TSX SCP 114 card to the TSX SCA 50 passive junction box on the Modbus trunk
• Modbus Network Topology: Supports bus topology with trunk cable (TSX CSA series) and multiple tap links (TSXSCPCM4030) to slave devices
• Electrical Isolation: Protects the PLC from ground loops, common-mode voltage, and transient noise on the field bus
• Flying Leads: Color-coded or labeled wire ends for direct connection to screw terminals or crimp connectors
• Passive Junction Box: TSX SCA 50 provides screw terminal connections for trunk cable and tap cables, with integrated line termination

Installation Guide

1. Install the TSX SCP 114 PCMCIA card into the PCMCIA slot of the TSX Premium or TSX Micro PLC.
2. Mount the TSX SCA 50 passive junction box near the PLC in the control cabinet.
3. Connect the TSXSCPCM4030 3-meter cable from the TSX SCP 114 card to the tap port on the TSX SCA 50 junction box.
4. Connect the TSX CSA trunk cable (100/200/500 m) to the trunk ports on the TSX SCA 50 junction box.
5. Wire the flying leads to the appropriate terminals on the junction box (observe polarity for RS-485 A/B).
6. Install line terminators (TSX FP ACC 7) at both ends of the Modbus trunk cable.
7. Configure the Modbus slave address and baud rate in the PLC programming software (Unity Pro or PL7).
8. Power on and verify communication via PLC diagnostics.

FAQ

Q: What does TSXSCPCM4030 connect?
A: It connects a TSX SCP 114 PCMCIA RS-485 card (in Premium/Micro PLC) to a TSX SCA 50 passive junction box on a Modbus serial network.

Q: What is the maximum cable length?
A: The TSXSCPCM4030 is 3 meters (9.84 ft) for the tap link. The Modbus trunk cable (TSX CSA series) can be up to 500 meters per segment.

Q: Is the cable isolated?
A: Yes. The TSXSCPCM4030 provides electrical isolation between the PLC and the RS-485 field bus, protecting against ground loops and noise.

Q: Can I use TSXSCPCM4030 with TSX SCP 111 or TSX SCP 112 cards?
A: No. The TSXSCPCM4030 is designed for the TSX SCP 114 (RS-485 isolated) PCMCIA card. TSX SCP 111/112 use different connector types and may require different cables.

Q: What is the difference between TSXSCPCM4030 and TSXSCYCM6030?
A: TSXSCPCM4030 is a 3m tap link cable with flying leads for TSX SCP 114 PCMCIA card. TSXSCYCM6030 is a 3m tap cable with a 25-pin SUB-D connector for TSX SCY 11601/21601 communication modules.

Q: Is TSXSCPCM4030 compatible with M340 or M580?
A: No. TSXSCPCM4030 is designed for Modicon Premium and Micro PLCs with TSX SCP 114 PCMCIA cards. M340/M580 use different communication modules and cables (e.g., BMXNOM0200, BMXNOC0401).

Selection Tips

• Premium/Micro PLC, Modbus RS-485, 3m tap link: TSXSCPCM4030 + TSX SCP 114 + TSX SCA 50
• Premium PLC, integrated RS-485 channel (TSX SCY 21601): TSXSCYCM6030 (25-pin SUB-D, 3m)
• Trunk cable options: TSX CSA 100 (100m), TSX CSA 200 (200m), TSX CSA 500 (500m)
• Line terminators: TSX FP ACC 7 (IP20, set of 2) or TSX EF ACC 7 (IP67 M23)
• Always verify: PLC model (Premium vs Micro), PCMCIA card model (SCP 114), and junction box type (SCA 50) before ordering
