S1DX Timers

UL File No.: E122222

CSA File No.: LR39291

Features
3 operation modes added for
fuller lineup

Output contact relay construction

Available contact relay output types: 2C and 4C

Now, operation modes include not only

On Delay, but Flicker, One Shot, and
One Cycle modes as well.

Panels can be installed

Operation can be
checked easily

In addition to conventional DIN rail

installation, panels can be installed using
an mounting frame.
The compact timer size means that larger
panels can be used.

Power supply: Green

Operation: Orange LED display

Output terminal
A plug-in terminal and printed
circuit terminal are provided.

Compliant with UL,

CSA and CE.
Easier than ever to
read and use
Large-sized transparent dial
makes setting time easy!

High precision
Repeatability error: 1%

Precautions during usage
1. Terminal wiring
Make sure that terminals are wired carefully and correctly, referring to the terminal layout and wiring diagrams.
2. Assembly
1) A dedicated terminal base or socket
should be used for attachment.
2) To assure that characteristics are
maintained, do not remove the case.
3. Rest periods
After unscheduled operations have been
completed, or if the timer operation
power supply has been turned off at any
time during operation, a rest period of at
least 0.1 seconds should be allowed
before resuming operation.
4. External surge protection may be
required if the following values are
exceeded. Otherwise, the internal
circuit will be damaged.

6. Soldering and cleaning

1) A flux-tight construction is not used
with this timer, so be careful that flux
does not get inside the case.
2) Terminals should be soldered by hand
(at a soldering iron temperature of 300C
572F, for less than 3 seconds, using a
30 to 60 W soldering iron). Automatic
soldering should be avoided.
3) Cleaning should be avoided as much
as possible. If the timer has to be
cleaned, make sure no cleaning fluid
gets inside the main unit case.
7. Installing the unit
1) The wire spring included in the product packaging is for the HC relay terminal block.
2) The wire spring is not usable with an
HJ relay terminal block, so the stopper
plate spring B (ADX18012: HJ relay terminal block plate spring) (sold separately) for the S1DH should be purchased.
8. Others
1) When connecting the operating power
supply, make sure that no leakage current enters the timer. For example, when
performing contact protection, if set up
like that of fig. A, leaking current will
pass through C and R, enter the unit,
and cause incorrect operation. The fig. B
shows the correct setup.

Time (s)

The typical surge absorption elements

include a varistor, a capacitor, and a
diode. If a surge absorption element is
used, use an oscilloscope to see
whether or not the foreign surge exceeding the specified value appears.
5. Phase synchronization using AC
load
If the turning on of the timer output relay
is synchronized to the AC power supply
phase, there may be times when the service life is shortened because of electrical factors, or when a locking phenomenon (defective relay return) occurs
because of contact point welding or a
shift in the contact relay. Check the operation using the actual timer.

When a contact switch having an operation indicating lamp (lamp equipped limit
switch, etc.) is used to apply power to
the timer, a resistor having a value equal
to or greater than the value below shall
be connected in series with the lamp.

2) When setting the time, the dial should

be kept within the range indicated on the
dial face. The 0 marking on the dial
indicatesf the minimum time during
which the control time can be varied (it
does not indicate 0 seconds).
9. Acquisition of CE marking
Please abide by the conditions below
when using in applications that comply
with EN61812-1.
1) Overvoltage category II,
pollution level 2 (2 Form C type)
Overvoltage category II,
pollution level 1 (4 Form C type)
2) The load connected to the output contact should have basic insulation.
This timer is protected with basic insulation and can be double-insulated to meet
EN/IEC requirements by using basic
insulation on the load.
3) Please use a power supply that is protected by an overcurrent protection
device which complies with the EN/IEC
standard (example: 250 V 1 A fuse, etc.).
4) You must use a terminal socket or
socket for the installation. Do not touch
the terminals or other parts of the timer
when it is powered. When installing or
un-installing, make sure that no voltage
is being applied to any of the terminals.
5) Do not use this timer as a safety circuit. For example when using a timer in a
heater circuit, etc., provide a protection
circuit on the machine side.
