Control By Web X-301 WebRelay-Dual 2-Relé, 2-Inngangsmodul

X-301 er en robust, fullverdig, web-aktivert, mini Ethernet I/O-modul med to digitale innganger og to 3A reléer som kan styres individuelt.

  • Inneholder (2) 3A, 28VAC/24VDC reléer og (2) optisk-isolerte digitale innganger
  • Tillater planlegging, logging, BASIC-tolk, e-postvarsler, tellere og peer-to-peer
  • Støtter protokoller inkludert HTTP, XML, Modbus, SNMP, SMTP, Remote Services


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.

  • 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).
