Ideal For Differential Level Control For Pump Up and Pump Down Applications
This product series is no longer available.
The SSRL series are latching 5 amp SPST Normally Open relays with a small output current to sense the
closing of up to two dry mechanical relay contacts. They are ideal for differential level control for
pump-up or pump-down applications when combined with any two level switches with dry relay contact
closures, such as 2 LV-10 switches or 2 LV-230 switches, for example. The SSRL relays also convert
non-latching mechanic relay outputs into latching alarm outputs, or allow low power reed relay switches
to control high amperage or high voltage devices, such as pumps or motors. Latching operation is reset by
making a momentary contact between the COM and OFF terminals. The SSRL holds its operational state for up
to 1/2 second during momentary power loss to avoid nuisance shutdowns. A short between the COM and OFF
terminals shuts the relay off, regardless of the switch status at the ON terminal.
SPECIFICATIONS Load Size Voltage Loss: 2 Vac Maximum Relay Closure Sense Current/Voltage: 20 mA @ 11 Vdc nominal Minimum Load: 10 times the leakage current Leakage Current Through Load Terminals: 2 mA at 120 Vac; 4 mA at 240 Vac Housing Material: Polysulfone
注: The SSRL Series Relays are not failsafe; we recommend a third level switch independent of the SSRL for alarm of overfill or overdrain conditions.
