Contributes to con-
trol panel and device downsizing.
鈥?Equipped with PA relays with high-
sensitivity twin contacts and Au-cald-
ding.
Equipped with 5 mm
.197 inch
wide PA
relays. The PA relays feature high sensi-
tivity (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.
RT-3 UNIT
RELAY
(PA Relay type)
鈥?Can be used mounted on a DIN rail or
mounted directly (by screw).
鈥?Equipped with an LED display to al-
low easy con鏗乺mation of operation.
鈥?Incorporates a surge absorber.
Incorporates an absorber circuit for coil
surges. This protects the circuitry of the
controller and prevents operation errors.
鈥?Relay installation and removal can be
easily accomplished with the removal
key accessory.
鈥?Includes a cover as standard equip-
ment for increased safety.
