Time delay relays (TDRs) offer simple, reliable, and economical control irrespective of the application. The delay time adjustment is as simple as turning a knob. To start a motor, control a load, or affect a process time-delayed switching is provided. The use of time relay is typically in industrial applications and OEM equipment. Additionally, for targeted logic needs, such as in a small panel or in sub-panels they play a very important role. Various features and operating characteristics are present in this such as simplicity, compactness, affordability, and easy use. In the case of a standard control relay, when voltage is applied to the coil contacts get immediately closed and open immediately when voltage is removed. In different applications, it’s necessary to have the operation of the contacts delayed along with application or removal of voltage. The problems are solved by a 12v dc timer relay handily. However, after the voltage is applied some TDRs postpone the closing of the contacts while others close the contacts, and then after a delay, they reopen them. TDRs are generally available as plug-in devices, much like plug-in control relays. However, in a variety of other forms such as base-mounted devices and direct IEC DIN controls they are present. For example, on a motor starter, a TDR can be fixed. There is the availability of even Electronic; starter-mounted TDRs. Few TDRs instead of relay outputs have solid-state outputs. www.facebook.com/OfficialMebaMCBTraditionally, the availability of TDRs was only as single-function, single-time-range devices. Still, these devices are available and in applications where the timing needs to be locked in, they are typically used. Today, with multiple timing ranges and functions many TDRs are available.
Single-shot timers Like the off-delay TDR, a single-shot abb timer relay has voltage and control inputs. When voltage is applied nothing happens. The contact transfer and timing begin with the closure of the control input. With timing, the control input can be left opened and closed or open, closed. In every case, timing continues, and the contacts remain closed. A contact gets transferred only at a time out. Removing voltage is the only means to interrupt the operation. Follow us on Facebook
