SainSmart 24V Relay Cycle Timer Module - Programmable with Customized Settings, 18 Modes
<p><b>Upgraded with New Features: </b><br> 1) Auto protection against faulty wiring: will not damage due to wrong connection of polarity;<br> 2) Function increased from 8 kinds to 18 kinds.<br> 3) Minimum time setting enhanced from 1 second to 0.1 second.<br> <br> <br> It is programmable using the four buttons onboard, to set up to 18 customized modes, including automatically repeating a set time cycle.<br> The 18 modes include: close or disconnect upon a certain set time; cycle mode 1 and 2 (cycle time 0 second to 270 hours); self-lock relay mode; trigger relay mode; limited cycle mode 1 and 2. It can be adjusted between a delay time of 0.01 second ~ 99 days 23 hours.<br>  </p> <p><b>Features:</b><br> Infinite loop timing mode<br> Finite loop timing mode<br> Latching relay mode<br> Trigger relay mode<br> Timing pull<br> Timing is disconnected<br> Timing pull off again<br> Then pull off the timing<br> Trigger timing pull off again<br> Timing off and then pull the trigger<br> Infinite loop timing mode<br> Finite loop timing mode<br> Pull the trigger timing<br> Disconnect the trigger timing<br>  </p> <p><b>Specifications:</b><br> Control voltage: AC 0~250V / max. 10A, DC 0~30V / max. 10A<br> Size: 2.59*1.57*0.67 inches <br>  </p> <p><b>Two module interface:</b><br> Relay outputs: a 3-wire interface, all interfaces are terminals<br> 1------- NO: normally open relay interface, the relay becomes vacant before, pull shorting after the COM1<br> 2---------COM: Common Interface Relays<br> 3--------- NC: normally closed relay interface relay shorted before and COM1, pull vacant post<br>  </p>
