6V Timers
Q: Are there any
IDEC timers that run on 6VDC?
A: No. We only offer timers in
12VDC, 24V AC/DC, and 100-240VAC.

Complex Timing
Functions
Q: I have a
situation that seems to require 3 or 4 timers, what can I
do?
A: Consider using one of IDEC's
PLCs or our IDEC Smart Relay. Four timers and sockets cost
more than our Micro-1 starter kit and are less flexible.
Three timers and sockets cost more than our IDEC Smart Relay
starter kit and are less flexible. Consider the amount of
time involved in wiring and trouble shooting a timing
function that requires more than 2 timers.

GT3A Timer Part
Numbers
Q: What s the
difference between the GT3A-(1,2 or 3)A*** & GT3A-(1,2
or 3)EA***?
A: The number of pins, nothing
else (8 vs. 11 pins.). The part numbers with the
"E" (aka the "B type" are available only
for fitting existing sockets that may already be in use.

GT3A Timer Part
Numbers
Q: What's the
difference between the GT3A-(4,5 or 6)A*** and GT3A-(4,5 or
6)EA***?
A: The -(4,5 or 6)A*** has a
start, reset and gate (freeze) all tied into the power of
the relay. The -(4,5 or 6)EA*** have only a start and reset;
these circuits are not tied to any power (they are dry
circuits.) Both have 11 pins. The part numbers with the
"E" (aka the "B type") are available
only to accommodate light duty limit switches which cannot
switch the full voltage (i.e. 120VAC or 240VAC) that is used
to power the timer.

RTA timer
replacement
Q: What should
replace an RTA timer?
A: RTA series were
electro-pneumatic and they have been discontinued. Our new
timers use a much more reliable and accurate solid state
timing circuit. Specifically, cross the RTA as follows
:RTA-SP2N (ON-Delay) can be replaced by GT3A-2..., RTA-SP2F
(OFF-Delay) can be replaced by GT3F-2... with the following
differences: contacts wired differently and the RTA had an
instantaneous contact and a delayed contact, the GT3F-2 only
has delayed contacts.

RTB timers
replacements
Q: What should
replace the RTB series?
A: For pin types only: the RTE
or GT3 series. There is no current IDEC timer that uses the
same blade layout at the RTB, although the RTE-B does have a
similar type of termination but with a different footprint.

RTE Input
Q: How does the
signal switch work on the RTE-*2*?
A: The switch serves as a signal
to the timer only. It must not carry any current or voltage
(it is a dry circuit.)

RTE-BN/RTE-BI/RTE-BF/RTE-BS
Replacement
Q: What is the
replacement for an RTE-BN, RTE-BI, RTE-BF, or RTE-BS timer.
A: The RTE-BN and RTE-BI are
replaced with the RTE-B1. The RTE-BF and RTE-BS are replaced
with the RTE-B2. They are direct replacements which differs
only in that the newer models are multi-function (function
is selected with a dip switch on the face of the timer).
Note that part numbers are incomplete without time range
group codes and coil voltages.

RTM timer
replacement
Q: What should
replace RTM motor driven timers?
A: They must be crossed on an
individual basis. Please know which timing function you need
(ON Delay, OFF Delay, Cycle, etc.) If you want a timer that
indicates its position in the cycle you probably want a GT3D
with a digital display.

RTY timers
replacements
Q: What should
replace the RTY series?
A: The GT5Y series uses the same
socket and offers multiple time ranges in a single unit.
