They are designed for hard-wired logic automated systems to complement the functions of industrial programmable logic controllers (PLCs). They are suitable for a wide range of applications, including:
  • Machines: single machine, and industrial automation and processes
  • Buildings: lighting control, access control door locks, roller shutters
  • Water segment: pumping and irrigation systems
  • HVAC: fans and centralized water systems

Applications These timing relays enable simple automation cycles to be set up using wired logic. They can also be used to complement the functions of PLCs.
Output Solid state  Timing relays with solid state output reduce the amount of wiring required (wired in series). The durability of these timing relays is independent of the number of operating cycles. Relay  Relay outputs provide complete isolation between the supply circuit and the output. It is possible to have several output circuits.

There are three main families of timing relays: 
  • DIN rail mounted Modular relays (RE17, RENF, and RE22) designed for mounting on DIN rails in an enclosure
  • Miniature plug-in relays (REXL) designed to be plugged into sockets
  • Panel mounted/plug-in relays (RE48A) designed for mounting on the front panel to give users easy access to the settings
These relays have 1, 2, or 4 outputs. For some references from RE22 and RE48 range, the second output can be either timed or instantaneous. If the power is switched off during the timing period, the relay reverts to its initial position. The Harmony Timer simple-to-use innovative NFC timing relay is enabled and controlled by the Near Field Communication technology available in present-day smartphones.  Application examples:
  • Opening of automatic doors
  • Alarm
  • Lighting in toilets
  • Car park barriers, etc.

Harmony Timer are timing relays designed to time events in industrial automation systems by closing and opening contacts before, during, or after a set time period. They are designed for hard-wired logic automated systems to complement the functions of industrial programmable logic controllers (PLCs). They are suitable for a wide range of applications, including:

  • Machines: single machine, and industrial automation and processes
  • Buildings: lighting control, access control door locks, roller shutters
  • Water segment: pumping and irrigation systems
  • HVAC: fans and centralized water systems

Depending on the product model, these relays support multiple time ranges


 

The Harmony Timer relays also feature:

  • Wide power supply range from 24 to 240 V z
  • Single or multi-timing ranges from 0.02 s to 999 hrs

Presentation of Harmony Timer Relays

A timing relay is a component that is designed to time events in industrial automation systems by closing or opening contacts before, during, or after a set timing period. There are three main families of timing relays: 

DIN rail mounted Modular relays (RE17, RENF, and RE22) designed for mounting on DIN rails in an enclosure
Miniature plug-in relays (REXL) designed to be plugged into sockets
Panel mounted/plug-in relays (RE48A) designed for mounting on the front panel to give users easy access to the settings
These relays have 1, 2, or 4 outputs. For some references from RE22 and RE48 range, the second output can be either timed or instantaneous. If the power is switched off during the timing period, the relay reverts to its initial position.

The Harmony Timer simple-to-use innovative NFC timing relay is enabled and controlled by the Near Field Communication technology available in present-day smartphones. 

Application examples:

  • Opening of automatic doors
  • Alarm
  • Lighting in toilets
  • Car park barriers, etc.
