Auxiliary Relays
Flashing Relay
The flashing relay type BR25 is used to obtain flash voltage in the control and signalling systems. The relay operation is monitored with two LEDs on the relay front plate. Flash time can be adjusted by a transparrent button.
When the relay is energized, the output rela starts with pick-up and then flashes according to the set time.
Impulse Relay
The Impulse relay WR25; has been designed to be used in various control and signalling circuits. When the relay is energized, the output relay picks up and after expiry of set time it drops off. It is reset by de-energizing. Pick-up and drop-off of the relay can be monitored by two LEDs on the relay front plate. Impulse time can be adjusted by a time button.
Pick Up Delay Time Relay
The pick-up delay time relay type ZR 20; is intended for use as a time-lag element for all kinds of control, protection and signal systems (e.g. in star -delta start-up circuits of motors, in automatic control circuits, etc.) Repetition time error is decreased very much thanks to its digital oscilliator. The tİme measuring process is based on pulse counting instead of usual electrolytic capacitors , thus the relays can perform with consistent accuracy over a large number of operations over long periods. On the front the relay has two LEDs for indication,one for indication of starting time and the other for indication of the relay operation.
Drop Off Time Relay
In installations having large number of motors, at high voltage drops or at short period of voltage failures the contactors and thus the motors will be out of operations. If the voltage comes after a short time, it is necessary the installation to be built up again and thus the motors to be taken into service. The relay is a drop-off delay yime relay providing restarting of the motors automatically at the system voltage recovery within a short period.
(Time relay counting when operation voltage is de-energized)
Horn Auxiliary Relay
The type KR30 horn auxiliary relays are used to energize and de-energize acoustic alarm devices (horn,siren,bell ,etc.) in signalling systems. These relays operate with short period impulses (minimum 50 ms) received from the type IR101 and IR521 signalling relays. When an impulse is received, the relay armature attracts, the alarm relay seals itself via the alarm silence push-button and through the other contects of numbers 15/18 and 25/28, it is recommended these contacts to be connected in series.
