Description
DIN43650B Solenoid Valve Timer – 2 Sec ON / 0.5–120 Min OFF
The SVT11B is a compact solid-state repeat-cycle solenoid valve timer designed for automatic condensate drains and other intermittent fluid control applications.
The timer switches the connected solenoid valve ON for a fixed 2-second period, then switches it OFF for an adjustable interval from 0.5 to 120 minutes. This ON/OFF sequence repeats continuously while electrical power is applied.
Designed for direct mounting between a DIN43650 Form B solenoid coil and electrical connector, the SVT11B provides a simple automatic control solution without requiring a PLC, external timer or control panel.

Operating Sequence
When electrical power is applied, the SVT11B energises the connected solenoid valve for approximately 2 seconds.
The valve then switches OFF for the selected interval between 0.5 and 120 minutes.
After the OFF period has elapsed, the valve is energised again for 2 seconds and the cycle repeats continuously until the electrical supply is removed.
Typical Applications
Automatic condensate drain valves
Air compressors
Compressed air receivers
Refrigerated air dryers
Compressed air filters
Moisture separators
Timed water discharge
Chemical dosing
Lubrication systems
Automatic flushing
Industrial automation
OEM machinery
Installation
The SVT11B mounts directly between a compatible DIN43650 Form B solenoid coil and electrical connector.
No separate control panel or PLC is required. Simply install the timer, select the required OFF interval and connect the electrical supply.
The integral TEST button allows the connected solenoid valve to be manually operated during commissioning, maintenance or adjustment.
