  1. hi, I think that the best plc is the one that you know best.
  2. Current Rating

    thanks gerry! so the air gap distance between the contacts should be calculated with respect to the voltage to prevent current from flowing in without even closing the contacts. regards.......paw
  3. Hi, I am confused. A relay contact has a rating of 230Vac 3A, 24Vdc 3A. Does this mean that current only affects the relay contacts and voltage has nothing to do with it? Is the there no difference with the effect of 230Vac and 24Vdc? regards, paw

  5. Hello, We have a multiple speed detective relay: terminals: 2-7 dc supply voltage 24v 4-5 AC input 2v~300v 1-3 H (NO) 6-8 L (NO) The set revolutions for H is 2070 rpm and 450 rpm for L, as far as I understand it H and L will be ON if it reaches the set value respectively. This will be detected on the ac input (4-5). The dials for H and L are mark from 0 to 10. Are the dials for H and L represents the percent setting of the set value? How does it exactly operates? Actually this device was installed on the automatic control panel of the genset to detect the speed of the the genset. I tried contact the supplier of the genset but I got no reply from them. The brand name of the device is IIZUKA DENKI SEIKUSHO CO., however I could not find the site. Maybe somebody here can help me. Thanks in advance, Paw
