Technical Specifications

Installation Guidelines

• Ensure the SLC 500 system power is disconnected before installing or removing the module from the chassis.
• The module should be inserted into an available slot in the SLC 500 rack; ensure it is fully seated and the retaining screws are tightened to provide a secure ground connection.
• Use shielded cables for high-speed signal inputs to minimize electromagnetic interference (EMI).
• Route signal wiring away from high-voltage power lines and AC motor drive cables.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.

FAQ

What is the primary function of the 1746-HSCE?

The 1746-HSCE is a specialized I/O module for the SLC 500 platform that processes high-speed pulse inputs from encoders or proximity sensors, which standard digital input modules cannot capture due to scan time limitations.

Is this module compatible with all SLC 500 processors?

The 1746-HSCE is designed for the SLC 500 family. Please verify your specific processor firmware and rack configuration to ensure compatibility with the module's I/O mapping requirements.
