12S, 14S, 15S Series Time Delay Relays and Sequencers
store.tremtech.comTime Delay Relays and Sequencers The Therm-O-Disc type 12S, 14S and 15S series time delay relays and sequencers are field-proven devices for controlling the operation of heating elements and/or fans in electric furnaces and heat pumps. These controls combine a solid-state positive temperature coefficient (PTC) heater with
Multi-functional Timer relay.
images-na.ssl-images-amazon.comthe time delay relay & de-energize the output. The timer function #1 is ON DELAY, it allows to supply power after a period of time (t). There are two timing charts, one without a trigger and one with the trigger. Trigger selection can be done during timer configuration. Let’s look at the first chart where the timer is triggered by the ...
Protective Relay Settings - Pangonilo
pangonilo.comThis is because the time delay T is the operation time of the relay when the current reaches 10Is. Hence, the time delay of the IDMT tripping may be set either by: T (s): operation time at 10Is or TMS: where TMS = T/ β Example: For 100/5 CT with P.S at 100%, TMS=0.1, using the standard inverse 3/10 curve, the SEPAM relay will be set
Fuji 1/16 DIN Super Timers - AutomationDirect

FUNDAMENTAL RELAY-OPERATING PRINCIPLES AND …
www.gegridsolutions.com18 FUNDAMENTAL RELAY-OPERATING PRINCIPLES AND CHARACTERISTICS Time delay is obtained in induction-type relays by a "drag magnet," which is a permanent magnet arranged so that the relay rotor cuts the flux between the poles of the magnet, as shown in Fig. 4. This p roduces a retarding effect on motion of the rotor in either di rection.
