Hioki Meter Relays are industrial 1-channel devices to assist in energy saving and automation implementations. The 2104 series are 1-channel ±1.5% class meter relays featuring a sensitive 1 µA, 10 mV DC movement and a customizable scale.

Key Features

  • Ultra sensitive 1 µA, 10 mV DC movement
  • Includes a display lamp to illuminate movement at a glance
  • Relay action delays circuit closure upon power on
  • Both power circuitry and relay built-in

H-type: Lamp lights up and output relay contact operates at deflection of the needle to the right of the setting needle.
L-type: Lamp lights up and output relay contact operates at deflection of the needle to the left of the setting needle.
HL-type: Provides functionality of both H- and L-type models.
