SWITCHING OPERATIONS
■ INTERLOCKING SWITCHING CONTROL (single-pole contact)
Single contact is used to switch from Signal Channel 1 (A1 – B1) to Signal Channel 2 (A2 – B1) and vice versa.
Terminal 3 – 9 OFF (open)
Terminal 3 – 9 ON (closed)
Status LED turn on when the respective channels are alive.
• Switching Status
Power : OFF
Switching command : OFF (open)
Power : ON
Switching command : OFF (open)
Power : ON
Switching command : ON (short)
*1. Resistor is provided only for the input code 2: Current signal (receiving resistor 50 ).
Power : ON
Switching command : OFF to ON
or
Power : ON
Switching command : ON to OFF
*1. Resistor is provided only for the input code 2: Current signal (receiving resistor 50 ).
■ INDEPENDENT SWITCHING CONTROL (double-pole contact)
Double contacts are used to independently switch Signal Channel 1 (A1 – B1) and Signal Channel 2 (A2 – B1).
Terminal 3 – 9 OFF (open)
Terminal 3 – 9 ON (closed)
Terminal 6 – 9 OFF (open)
Terminal 6 – 9 ON (closed)
Status LED turn on when the respective channels are alive.

When the switching command contact is switched from
OFF to ON or from ON to OFF, the signal channel is
switched only after all photo MOSFET relays turn on
(closed).
