2103 METER RELAY
OVERVIEW
Advancing power saving and automation
  • Electronic design assures high accuracy and reliability
  • Ultra sensitive 1 µA, 10 mV DC movement
  • Both power circuitry and relay built-in
  • Includes a display lamp to illuminate movement at a glance
  • Relay action delays circuit closure upon power on
