Buying Edwards parts
- Quote the part number – Edwards parts are ordered by code (for example 4-NET-TP or SIGA-OSDI); check the label on the existing module.
- European versions – codes ending in -E are European (EN 54) versions; match these to UK and European systems.
- Isolator or standard – SIGI devices include a built-in isolator, and isolator bases are also available; follow the loop design.
- Network media – choose copper or fibre SFP controllers to suit the cabling between EST4 panels.
