Schneider Electric Harmony Time Series DIN Rail Mount Timer Relay, 24 V dc, 24 → 240V ac, 2-Contact, 0.1 s

A series of timing relays designed to time events by closing or opening contacts before, during or after a set time period. Ideal for industrial automation systems they can be mounted on DIN rails or directly. Enabling the set up of simple automation cycles using wired logic, these timers can also be used to compliment the functions of PLCs. Making it possible to have several output circuits this ranges relay outputs also provide complete isolation between the supply circuit and the output. Featuring a diagnostic button which assists with commissioning and troubleshooting these relays are also energy efficient and reliable with a wide choice of outputs (either screw or spring connection terminals).

Applications - Time Delay Relays are typically used in industrial applications and play an important role for many industrial processes such as small panel or sub-panels requirements. Other applications include:

• Lighting circuits
• Motor start control
• Sensitive equipment
• Safety control
• Conveyor belt sequence delay
• Machines, single machine and automation
• Buildings, door locks and roller shutters
• Water segment such as pumping and irrigation
• HVAC, fans and water systems

Off-delay function available in RS 791-2723

Tell your equipment what to do when with this timer relay from Schneider Electric. It has on-and-off delay functions to ensure connected machinery does the right job at the right time to keep your processes rolling smoothly. As it supports delays between 0.1s and 100h, this is a versatile option. Operating the unit is a piece of cake, thanks to its simple front-mounted selector switch. Installation is speedy and the relay snaps directly onto a standard DIN rail without the need for tools.

• Response time of less than 100ms for snappy switching
• Neat dimensions of 17.5 (W) x 90 (H) x 72mm (D) to take up minimal space in busy setups
• Setting accuracy of ±10% of scale, ensuring precise signal timing
• Protective cover cuts the risk of accidental adjustment
• Electrical service life of 100,000 operations for long-lasting control

• Food production
• HVAC systems
• Industrial automation

This relay comes with handy LED indicators that flash when it starts timing, so you can see at a glance if its delay is counting down.
