![]() Each channel has its own output, so you can run two different functions (one per circuit) at the same time. Select the voltage of the relay's attraction coil including 12VDC / 24VDC / 110VAC / 220VAC, etc., according to the voltage of the control circuit.Īir damping or electric time relays are better than transistors for occasions with large power supply voltage fluctuations, and electric time relays are not suitable for occasions with large power frequency fluctuations, and air damping timer relay is not suitable for large temperature changes. Control two steps of an electrical process from a single relay with two fully independent channels and 30 different functions, these relays give you a wide range of possibilities. The reset time after the action should be longer than the inherent action time, so as to avoid misoperation or even no delay, which is especially important in the case of repeated delay circuits and frequent operations.įor occasions with low requirements for delay time accuracy, generally use electromagnetic or air damping time delay relays with lower prices otherwise, for high requirements on time delay accuracy, electronic time relays can be used. Shop Plug-In 120V Variable Time Off-Delay Relay With 0.3-30 Minute Timing Range By Square D (Schneider Electric) (9050JCK27V20) At Graybar, Your Trusted. There are two types of timer relays, power-on delay or power-off delay, which should be selected according to the requirements of the control circuit. A special class of electromechanical relays called time-delay relays. The following aspects should be considered when selecting a time delay relay. When a relay contact is open, this will switch power ON for a circuit when the coil. The selection of timer relay mainly focuses on delay mode and parameter. Mode 4: Two group sync time delay output.The ON delay relay can power on one device slightly. Mode 3: One group suspension delay output A common use for an ON delay relay is to reduce the inrush current when powering on several devices at once.Mode 2: One group instantaneous and one group time delay output.Mode 1: External connecting reset, one group pause delay output The black hot wire goes through the power switch to the other side of the V+ power transformer and one terminal of the 12V timer relay NO contacts. ![]() ![]() Mode 3: One group suspension delay outputĬonnection Diagram & Output Operation Mode Mode 2: One group instantaneous and one group delay output Mode 1: External connecting reset, one group pause delay output High quality and accuracy digital timer relay / countdown timer is widely applied in the industrial automation field with power supply 24V DC or 85-265V AC. Digital timer relay or time delay relay, on-delay timer relay, has timing setting range of 0.01~9999 sec / 0.01~9999 min / 0.01~9999 hrs, easy to read with 4-digit dual time display. Time Delay Relays are electromechanical devices that turn a large load on or off through the use of a smaller control signal.
