Product information

Description

Delta EW-485/1/2/SO is a bidirectional optical isolation separator designed to transmit digital signals while providing galvanic isolation between connected circuits. The device employs optical coupling to separate input and output stages, which prevents ground loops and reduces electrical interference in communication lines. It is intended for use in industrial automation, protection of serial links, and maintaining signal integrity in building management and remote I/O systems.

Advantages

This optical isolator ensures reliable bidirectional data transfer while isolating different parts of a system electrically. By using optical coupling, it eliminates direct conductive paths that can carry transient voltages, improving noise immunity and protection against common-mode voltages. The compact design facilitates installation in control cabinets and on DIN rails, and the device supports long-term stable operation in typical industrial environments.

Suitable for

  • Isolating RS-485 or other differential serial communication lines
  • Protecting remote I/O modules and field devices from ground potential differences
  • Reducing interference in building automation and HVAC control networks
  • Ensuring signal integrity over longer cable runs in industrial systems

Key specifications

  • Bidirectional optical isolation for digital signal transmission
  • Galvanic separation between input and output circuits
  • Designed for use with differential serial communications and similar signal types
  • Compact form factor suitable for DIN-rail mounting in control cabinets
  • Improved common-mode noise rejection and transient protection through optical coupling

How to use

Install the isolator according to the control panel layout, ensuring secure mechanical mounting and correct orientation for signal flow. Connect the communication pair from the source device to the input terminals and connect the output terminals to the receiving device, observing wiring polarity for differential lines. Supply any required auxiliary power or reference connections as specified by the system design, and verify signal continuity and proper isolation before commissioning. Perform functional checks with the communication protocol active to confirm bidirectional data transfer and stable operation.

Usage recommendations

Place the isolator between sections of the network that experience ground potential differences or frequent transient disturbances. Use shielded twisted-pair cabling and proper termination for differential lines to maximize signal integrity. Regularly inspect terminal connections and mounting points as part of preventive maintenance to maintain reliable isolation and communication performance.
