Import Cp5512 — Buy in Bulk from Supplier in China

The CP5512 is a PCMCIA-based communication card designed for direct connection between a laptop and Siemens S7 series PLCs via Profibus, MPI, PPI, or FWL interfaces. It operates at data rates from 9.6 kbps to 12 Mbps, with a maximum communication distance compliant with Profibus standards. The card uses iCoupler isolation technology instead of optocouplers, providing enhanced signal integrity and durability under industrial conditions. It connects through a standard 9-pin Sub-D connector and requires a Siemens 6ES7 901-0BF00-0AA0 cable for fieldbus linkage.

The device is built with industrial-grade components to support operation across a temperature range of -20°C to +75°C. It features 15 kV ESD protection, 1000 VDC isolation voltage, and integrated surge protection rated at 4 kV and 100 A (10/700 µs). The RS485 interface includes overcurrent protection with auto-recovery, capable of withstanding continuous voltage up to 60 V. Power consumption is 1.0 W at 3.3 VDC, and physical dimensions are 130 mm x 54 mm x 5 mm, with a 22 mm height including the DB9 plug. Weight is 70 grams.

This card is used by automation engineers and system integrators who need reliable laptop-to-PLC communication for programming, diagnostics, or commissioning tasks. It is compatible with Siemens S7-200, S7-300, S7-400 PLCs, EM277 modules, and ET200 remote I/O systems. Buyers typically source it for replacement, backup, or retrofit applications where original Siemens units are unavailable or cost-prohibitive. Packaging is standard anti-static with cable included. Trade terms are typically FOB Shenzhen, with lead times confirmed upon order.
