#6342 — Timing relay providers

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:

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.
