*1: There is no internal protection circuit in the output relay of the PLC; therefore when activating an inductive load,

we suggest you parallely connect a reverse current protection diode to extend the life of the contact.

- The diode has to be able to endure max. 5 ~ 10 times of load voltage.

- The positive current of the diode has to be bigger than load current.

*2: Manual exclusive output uses external circuit and forms an interlock, together with the PLC internal program, to ensure

safety protection in case of any unexpected errors.

*3: There is no internal protection circuit in the output relay of the PLC; therefore when activating an inductive load, we

suggest you parallely connect a surge absorber (0.1uF + “100ohm to 120ohm”) to reduce the noise on AC load and

extend the life of the contact.

*1: Manual exclusive output uses external circuit and forms an interlock, together with the PLC internal program, to

ensure safety protection in case of any unexpected errors.

*2: Use a zener diode (39V) in the PLC to protect the transistor output. When activating inductive load, we sugget you

parallely connect a reverse current protection diode.
