Relay Port
What’s this?
• Vision provides one non-energized relay port, which can be, switched ON/OFF manually or automatically.
• The relay port can be operated locally as well as remotely.
• The external device that can be operated by this relay port should conform to the specifications of this port.
• In practical use, a load of 80-100W like a fluorescent tube-light, incandescent lamp, etc. can be operated
directly through this port without the need of a contactor.
• If heavy-duty devices like a 3-phase water pump, Air-conditioner, neon lamps, etc. is to be operated through
this port then a contactor of adequate rating should be used.
• Vision remembers the state of relay during power failure. Suppose, a water pump is being controlled using
this feature and if while it is running, power failure occurs then the operator need not turn the water pump
again on power restoration. Vision will retain the last state and will switch ON the water pump on power
restoration.
