2-wire Logic Modules
The 2LM3 is an on/off logic module that has the ability to be programmed for either LIGHT
or DARK operate. It comes with a jumper wire installed: with the jumper in place, the output
is DARK operated; with the jumper removed, the output is LIGHT operated. The 2LM3 is
used when no timing function is desired.
The 2LM4-2 provides a one-shot ("single shot") output pulse each time there is a transition
from LIGHT to DARK (jumper installed) or from DARK to LIGHT (jumper removed). The
output pulse time range is from adjustable from 0.1 to 1 second. The duration of the pulse
is independent of the duration of the input signal. The timing of the 2LM4-2 is restarted each
time the input signal is removed and then recurs. This is referred to as a "retriggerable" one
shot, and this feature may be applied to some rate sensing applications.
The 2LM5T "limit" timer combines the function of on-off logic and on-delay logic. As long
as the signal is present for only short periods of time, the output "follows the action" of the
input signal. If the input signal is present for longer than the predetermined time, the output
deenergizes. The output only reenergizes when the input signal is removed and then
reestablished. Interval timers are used to operate loads which must not run continuously for
long periods of time, such as intermittent duty solenoids and conveyor motors. Timing
range is adjustable from 1.5 to 15 seconds.
The 2LM5 is a true "on-delay" type logic module. The input signal must be present for a
predetermined length of time before the output is energized. The output then remains
energized until the input signal is removed. If the input signal is not present for the
predetermined time period, no output occurs. If the input signal is removed momentarily
and then reestablished, the timing function starts over again from the beginning. The
standard time range is adjustable from 1.5 to 15 seconds, and other ranges are available.
The 2LM5R is an "off-delay" logic module, similar to the 2LM5, except that timing begins
on the trailing edge of the input signal. When the input occurs, the output is immediately
energized; if the input is then removed, the output remains energized for the adjustable
predetermined time period, then deenergizes. If the input is removed but then reestablished
while the timing holds the output energized, a new output cycle is begun. The LIGHT/
DARK operate jumper wire option is included. Timing range is adjustable from 1.5 to 15
seconds, and op-tional ranges are available.
The 2LM5-14 combines the function of an "on-delay" and an "off-delay" into one logic
module. When the signal is present for more than the output on-delay time, the output
energizes. The off delay circuit is now active, and holds the output on even if the input signal
disappears for short periods of time. If the input signal is gone for longer than the off-delay
time, the output finally drops out. The time delays can control high and low levels in flow
control applications. Each delay is independently adjustable for 1.5 to 15 seconds.
Description of Logic
provides the LIGHT/DARK program-
ming of the output plus delay or pulse
timing, if required. 2-wire logic mod-
ules are all color-coded black (3- and
4-wire logic modules are red). The
timing ranges listed below are stan-
dard. Special timing ranges are avail-
able, on a quote basis, per the instruc-
tions given for 3- and 4-wire logic
modules on page 23. NOTE: model
LMT test module (page 23) may also
be used with 2-wire systems.
