Overview
The series III WebRelay-Dual™ (X-301) is a robust, full-featured, web-enabled, mini Ethernet I/O module with two, 3A relays that can be independently controlled, as well as two, optically-isolated digital inputs. It has non-volatile memory for logging, a real-time clock with support for NTP (time server) synchronization and an advanced full-calendar scheduler which can be used to turn on/off relays at preset times. Its web-based user interface means it can be used right out of the box with no programming required.
The series III WebRelay-Dual has many advanced features including a simple firewall, the ability to initiate a connection to remote servers, BASIC programming, SNMP, email alerts, peer-to-peer communications, internal monitoring, etc.
The series III WebRelay-Dual is ideal for many applications including security, remote control, street sign controllers, shift bell controllers, and much more.
Applications
The X-301™ is versatile and has many applications, such as:
Road signs/lights
Use WebRelay-Dual to remotely turn on road signs during hazardous conditions or automatically turn on signs for scheduled events.
Shift change bells
Use WebRelay-Dual to automatically turn on bells/horns for shift changes. If multiple bells are needed, WebRelay-Dual can be “daisy-chained” with other ControlByWeb relays for simultaneous alerts.
Ethernet I/O
WebRelay-Dual is a simple but powerful Ethernet I/O (or web I/O) device. The two relays and two inputs can be used for thousands of applications from event counters, to machine monitoring/control, to extending I/O from a PLC to another building and much more.
Gate Control
Use WebRelay-Dual to remotely control guard gates.
Vacant Living/Working Spaces
Make sure electronic devices are off when nobody is around. Save energy!
Security
Use WebRelay-Dual to lock/unlock doors or at preset times. An electric lock controlled by WebRelay-Dual can be used in conjunction with a mechanical lock to allow access at certain times. Persons with keys can access a building during the day while electric lock is off but access is denied at night when WebRelay-Dual turns on the electric lock. In addition, WebRelay-Dual can send email alerts when the door is opened (anytime or just when the door is locked).
