the control output goes toward minimum side.

The positioner is factory set to "Reverse" control action.

Specify "Operation Mode Selector" type (code 1) when ordering, if changing out-

put action to "Direct".

EXPLANATIONS OF TERMS

• SSR (Solid State Relay)

Composed only of semiconductor parts, SSR is free from arc discharge or chattering which is typical with electromagnetic

relays. It features excellent characteristics against vibration, physical impact or other environmental conditions.

• Zero-Cross Function

SSR with zero-cross function turns on when AC power voltage is near zero, creating delay of switching when input is provided in

the middle of an wave cycle, thus limiting transient switching noise voltage and rush current.

• Photo MOSFET Relay

A kind of semiconductor relay which has advantages of both solid state relay and mechanical relay, thanks to its low ON-

resistance characteristic. It also features high speed ON/OFF operation and low leak current.
