TRIP Operation with Isolated External Contacts
* This function can be set for isolation-option-featured type "model name with I" only.
The input for this machine can be shut off (switching stop by setting) using output from small capacity contacts or
photocouplers.
Use a photocoupler or a small signal relay or switch with a minimum contact capacity of 5V, 2.5mA.
Connecting
Wire the cables to the isolated control connector (accessory) terminals No. 9 and 10.
By connecting the external control connector (accessory) terminals No. 11 and 24, contact-b operation can be
performed.

 You can choose TRIP operation by short circuit (make) of contact a and TRIP
operation by opening (break) of contact b.
MEMO
 Not suited for power contacts such as main contacts for
electromagnetic contactors or power relays.

CAUTION
 The commons for contact point signal (external control connector No. 23,24) is internally
connected to the minus side of the output terminal.
 Isolation for the wire connecting to the external control should be more than the relative ground
voltage of this product.
Otherwise, the user may receive electric shock.
