Description

Solenoid Valve Repeat Cycle Timer – DIN43650A Form A

The SVT22 is an adjustable solid-state repeat-cycle timer designed to provide automatic ON/OFF control of solenoid valves without requiring a PLC or separate control system.

Mounted directly between a DIN43650A Form A solenoid coil and electrical connector, the timer energises the valve for the selected ON period before switching it OFF for the selected interval. This cycle automatically repeats for as long as electrical power is supplied.

A wide choice of timing ranges is available, from 20 millisecond pulse control through to 12-hour OFF periods, making the SVT22 suitable for automatic condensate drainage, lubrication, dosing, flushing, pneumatic control and general industrial automation.

OFF: 0.5–45 min

T5 / SVT22N-05

ON: 0.3–5 min

OFF: 0.5–60 min

T6 / SVT22N-06

ON: 0.5–10 min

OFF: 0.5–60 min

T4 / SVT22N-04

ON: 0.5–60 min

OFF: 0.5–10 sec

How the Repeat Cycle Works

When electrical power is applied, the timer immediately energises the connected solenoid valve for the selected ON period.

ON → Valve energised for T1

OFF → Valve de-energised for T2

REPEAT → T1/T2 cycle continues

The cycle repeats continuously until the electrical supply is removed.

Both ON and OFF periods are independently adjusted using the rotary controls on the front of the timer.

The TEST button allows manual activation during installation, commissioning and maintenance.

Analogue vs Digital Timer

SVT22 / TEC22 Analogue Timer

✓ Simple rotary adjustment

✓ No programming required

✓ Fixed adjustment range per model

✓ Ideal for repetitive ON/OFF control

✓ Lower-cost timer solution

Digital Timer

✓ Fully programmable ON and OFF times

✓ Timing from 1 second to ~100 hours

✓ ON/OFF or OFF/ON repeat operation

✓ Single Shot operation

✓ Digital LED indication

For applications requiring timing outside the selected SVT22 range or more advanced operating sequences, choose the TEC22 Digital programmable timer.

Took a little finding on such a big store, but now that I have cracked it I better understand the layout, I should pay more attention to the other products tab!!. anyway, easy to select time, pictures are OK but could do with improving, service is excellent, price is fine, quality of product very good much better than expected - hence I suggest you improve the pictures. Thanks for your prompt delivery. Alex.
