Schneider TSXSCP114 | PCMCIA Communication Card

The Schneider TSXSCP114 adds an extra serial communication port to TSX Premium PLCs. This PCMCIA communication card inserts directly into the CPU’s PCMCIA slot. You can connect additional HMIs, drives, or barcode scanners. The unit provides a fully isolated RS-485 interface for industrial networks.

This PCMCIA communication card weighs only 0.03 kg for minimal added bulk. The card measures 86 mm long by 54 mm wide. Its thickness reaches 5 mm for Type II PCMCIA compatibility. You can insert the Schneider TSXSCP114 into any TSX Premium CPU with a PCMCIA slot.

Interface and Connection Details

A 15-pin female D-sub connector provides the RS-485 interface. This connector carries Data+, Data-, and common ground signals. You will need a separate adapter cable for screw terminal connections. The front edge includes two LED indicators for transmit and receive activity. A label on the card shows the pinout diagram for easy reference.

Energy Storage and Internal Circuitry

The Schneider TSXSCP114 stores minimal energy for signal buffering. Small capacitors provide 22 µF of total storage for the communication controller. The card does not contain any battery for configuration retention. Instead, it reads all settings from the PLC configuration at power-up. Optocouplers provide 1500 VAC isolation between the port and backplane.

Component Layout and Construction

A dedicated UART manages all serial communication processing tasks. An isolated RS-485 transceiver drives the differential network signals. You will find 28 resistors, 22 capacitors, and 6 integrated circuits on the board. The Schneider TSXSCP114 includes transient voltage suppression for surge protection. A metal shield covers the top and bottom for electromagnetic interference reduction.

Operational Use and System Integration

Transitioning to this card expands your Premium system communication capacity. You can add a third serial port without occupying a rack slot. The card works with Schneider drives, HMIs, and third-party Modbus devices. Use the Schneider TSXSCP114 for data logging, remote monitoring, or device networking. For best results, terminate the RS-485 network with 120-ohm resistors at both ends.
