6-2-4 Relays
The following relays should be used with the interfaces:
Interface
Relay used especially for switching on-off analog input com-
mand and digital input command (interface DI-1) signals
Relay used for digital output signals (interface DO-1)
To prevent defective contacts, use a relay for small signal
(twin contacts).
(Ex.) OMRON: type G2A, MY
Small relay with 12VDC or 24VDC of 40mA or less
(Ex.) OMRON: type MY
Selection Example
The input power factor is improved to about 90%. For use with a single-phase power supply, it may
be slightly lower than 90%.
