RT-3 (Power PhotoMOS Relay type)
743
TYPES
Note: Only for use with Power PhotoMOS standard type relays. Cannot be equipped with PA relays.
RATINGS
1. Input ratings (per relay)
Note: This product has a built-in input current limiting resistor; therefore, it is not necessary to externally connect a resistor to the input. The input voltage
can be applied directly.
2. Output ratings (per relay, at 25°C 77°F)
Notes: 1. During 4-point operation, the rating of each relay is also as shown above.
2. The load current varies depending on ambient temperature. Refer to the Load current vs. ambient temperature characteristic data.

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.
• Power PhotoMOS relays, for high
reliability and long life, is installed.
This type is equipped with Power
PhotoMOS relays which have a
reputation for high reliability and long
life. Helps make devices maintenance-
free.
• 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 cross connection
preventing diode.
• Relay installation and removal can
be easily accomplished with the
removal key accessory.
• Includes a cover as standard
equipment for increased safety.
• The unit color of the Power
PhotoMOS Relay type is pale
lavender.
The unit color of the PA Relay type is
titanium gray.
