Numeric and alphanumeric displays are used in systems where information is so diverse that it can no longer be displayed using individual indicator lights.
3RP electronic timing relays are used for all time-delayed switching processes in control, starting, protection and regulating circuits.
SIRIUS Relays
Time Relays
3RP electronic timing relays are used for all time-delayed switching processes in control, starting, protection and regulating circuits. Our wide range of designs means that we have the ideal solution for every customer.
Application
On-delay
- for glitch suppression
- for the stepwise starting of motors to prevent an overload of the network
Off-delay
- for generating a follow-on function on removal of the control voltage (fan run-on)
as an emergency stop, or to put a plant in a defined state in spite of a power failure
Star/delta
- for switching motors from star to delta - with a switching interval of 50 ms in order to prevent inter-phase short circuits
Advantages at a glance
- All versions available with removable terminals and screw terminals or alternatively with the innovative cage clamp terminal system
- Universal use due to wide range of designs
- Reduction of model variants due to models covering 24 AC/DC - 240 V
