Controlling the Product Using Contact Signals
You can use an external sequencer contact signal output or a digital I/O controller through the
CONTROL INPUT terminal to select the product’s impedance. You can use the STATUS
OUTPUT terminal to check the product status.
CONTROL INPUT terminal
The current absorption by an external circuit activates the internal relay. Of Z1, Z2, Z3, and
BYPASS, only one can be selected at any given time. If all switches are off, no impedance is
selected, and the N-phase circuit is open. The internal relay operation current is approxi-
mately 100 mAdc (24 Vdc open voltage or less).
Example: Selecting impedance Z1
Set the REMOTE terminal to low level (connect to the circuit common). Next, set the Z1 ter-
minal to low level (connect to the circuit common). This will select impedance Z1.
STATUS OUTPUT terminal
Contact output. The contact is active when it is shorted. When shorted, the contact is con-
nected to the internal circuit common (contact rating of 5 Adc, 35 Vdc). When the contact is
opened, the terminal potential is also opened.
