  3. XMTD 2001 temperature controller

    Hello experts.. i purchased XMTD 2001 temperature controller .but i dont know about its pins that where to connect the AC suppy ,thermocouple and from which pin it will give output signal for PLC. if anyone have its datasheet kindly share it to me.if some one worked with it kindly help me.. Thanks... ect_09...........
  4. motor interfacing

    Hello Experts.. i want to ask that how to interface DC motor that is rated as 24V and 1.5A .. i made H-Bridge for that to protect PLC from demaging output bit.... but tell me that how to interface motor..h-bridge has two pins.. i put one wire in Q0.0 and other in Q0.1 ..making 1 and 0 , 0 and 1.. but motor doesnot work..tell me the possible soluton..

  10. how to work without retentive timers

    hello experts.....!!! its done.i used M1013 that is 1sec clock(0.5sec off and 0.5sec on) ,i give this pulse to retentive counter that is counting pulse .e.g i set the value of counter is 5 then its means 5sec delay. because pulse just add value in timer after 1 sec... its working. am very happy...... you save me from insult by my supervisor..
