FEATURES
• Space-saving type with four
independent points on a base
measuring 33 × 67 mm 1.299 × 2.638
inch. This contributes to a more
compact control panel.
• PA relays, which have high
sensitivity Au clad twin contacts, is
installed.
PA relays, 5 mm .197 inch wide, is
installed. The PA relays feature high
sensitivity (12 V type: 120 mW, 24 V
type: 180 mW) and twin contacts with
Au-cladding, which combine to ensure
high reliability even with minute loads.
• Can be mounted on a DIN rail or
mounted directly (by screw).
• Equipped with an LED display to
allow easy confirmation of operation.
• Incorporates a surge protector.
Incorporates an absorber circuit for coil
surges. This protects the circuitry of the
controller and prevents operation errors.
• Relay installation and removal can
be easily accomplished with the
removal key accessory.
• Includes a cover as standard
equipment for increased safety.
