Littelfuse delivers vital products to address customer needs for protecting and safely controlling electrical power. Our single-function & control relays product portfolio includes 2 series of delay-on-make/delay-on-break time-delay relays that work in ac and dc systems. Each version boasts excellent repeat accuracy. These relays can be used to start a motor when a button is pushed and allow the motor to operate for a set period of time. Available features include microcontroller-based circuitry, solid-state components, encapsulation, and LED indicators.
- Ac input voltages from 24 V ac to 230 V ac
- Dc input voltages from 12 V dc to 48 V dc
- Fixed or selectable time delays from 1.5 s to 1230 s
- Repeat accuracy as high as ±0.1 % or 20 ms, whichever is greater
- Operate at temperatures up to +85 °C
- Reset times ≤ 150 ms
- Initiate times ≤ 40 ms
- Time delays vs. temp. & voltage ≤ ±2 %
- Ac line frequency/Dc ripple of 50/60 Hz with accuracy within 10 %
- UL Recognized
- Available with DPDT or SPDT output circuitry
- Available with digital or microcontroller-based circuitry
- Compact, low-weight designs
