Trends
• 75% of Installed Base of Relays are Electromechanical
• 90% of New Relays Purchased are Digital/Electronic
• Lingering Issue of “Putting All Eggs In One Basket”– “No Backup”
– “Like to See Disk Move”
– Solve with Backup (such as DIAC as backup to SR760 or F60)
– Gain Excellent Accuracy and No Setting Drift
• Manufacturers have Created Relay Families, thus reducing maintenance, O&M costs and training.
