Post by thread:[OT] latching relay control

I have someone who wants to control this from a single output http://www.hansphin.com/Documents/Y20S-1.pdf Pretty sure for a 24VDC, you need to swap the + and - controls to latch and unlatch? Seems typical but just seeing how others interpret the datasheet

I see it as the coil is held in in either position, hit the momentary switch and the relay switches. hit the switch again and it changes back to original position. The coil works with DC or AC. The DC doesn't care which way it flowing.

For DC a positive pulse switches on, and a negative going pulse switches off. Or indeed just swap the terminals around.

I concur, after I clicked send, I noticed the arrangement of diodes. The relay position follows the switch position, either AC or DC. :) On 1/20/2012 4:00 PM, cdb wrote: {Quote hidden}> On Fri, 20 Jan 2012 14:47:44 -0500, Carl Denk wrote: > :: I see it as the coil is held in in either position, > > I see it differently (black for active confused me momentarily), for AC the > positive half of the wave form causes a positve rectified half wave which > switches the coil to the On position and a negative going half wave > rectification causes it to move to the OFF position. > > For DC a positive pulse switches on, and a negative going pulse switches > off.
