  • Timing relay providers

    From David Lesher@21:1/5 to All on Mon Apr 23 20:25:34 2018

    I seek a timing relay with some/all of the following:

    a) LV operation, 12-24VDC or AC

    b) Input triggers a one-shot output

    c) Intervals in hours, 1-14 or so.

    d) Reset that will terminate the one-shot, and await the next
    trigger.

    e) Two selectable one-shot times; this one I can handle
    with 2 relays with the outputs in parallel.

    I am looking at Crouzet, TE Connectivity, Omron, etc.
    Don't yet find any with reset inputs.

    Any suggestions?

    Ebay has a bunch of multifunction timer modules, like this one
    (watch out for line wrap) that might work for you: https://www.ebay.com/itm/Digital-LED-Display-Infinite-Cycle-Loop-Delay-Timer-Switch-ON-OFF-Relay-Module-/191910820176?var=&hash=item2caec6b950:m:mi4wzCdMQFz8atu5Pq5ywUQ

    Have a look on 'programmable relays', i.e. small PLCs that are available
    from multiple vendors. Smallest ones typically have something like 4
    output relays and 4-8 inputs.

    wire ~reset to "+12 in"

    In other words to reset turn off the power to the relay.

    This probably requires that the reset pulses are several milliseconds
    long for reliable operaton.

    I'm looking at the 175MD <https://www.marshbellofram.com/automatic-timing-controls/products/175md-din-rail-mount-multi-function-timer/>
    I'll have to open the power to reset, but Mode Q offers
    resetting the timeout that would be useful in this appliaction.

    They also have the brick TSE that is about the same price.
