Relays

Precision DIN-rail
mounted timing relays
for any industrial
application

Sprecher + Schuh’s new RZ7-FS preci­sion electronic timing relays offer 19
different output functions applicable
to all types of industrial control.
In addition to standard
and OFF-Delay relays, the series also
includes many specials such as an
Delay that operates without supply
voltage. Various timing ranges from

0.05 seconds to 60 hours are available,
with many relays offering multi-time
setting capability in the same device.

Solid state accuracy and
reliability

Except for their hard silver contacts, all
RZ7-FS timing relays are built with solid
state electronics and controlled by a mi
croprocessor. ey are accurate to within

0.2 percent. eir ruggedness and high
level of accuracy is due to the thorough
testing of function, timing characteristics
and surge voltage strength performed on
each device prior to shipment.

In addition, RZ7-FS relays function
reliably from 15% under rated oper
ating voltage to 10% over rated voltage
(AC). Voltage tolerance is even greater
in DC applications.

-

Multiple functions and
timing ranges in one relay

e RZ7-FSM combines eight separate
timing functions (plus ON and OFF
functions) into one device. In addi­tion, ten timing ranges are individually
selectable from 0.05 seconds to 60
hours. ese special relays reduce in
ventories and are ideal for maintaining
remote installations where stocking
several different timing relays would
not be practical.

RZ7-FS

The new multifunction RZ7-FSM Electronic

Timing Relay provides eight different timing

functions and ten different timing ranges.

Eliminates additional relays

e standard RZ7-FS is supplied with
one single pole double throw
contact within a compact case only

22.5mm wide. If more contacts are
required, several relays are available
that provide two separate, electrically
isolated SPDT contacts within the
same narrow footprint. Output two is
selectable as an instantaneous contact,
which can eliminate the need for aux
iliary relays in complex installations.
ese two pole relays can also be used
with an external potentiometer for
remote time setting.

(SPDT)

convenience features

• Every RZ7 accepts a broad range of
AC and DC supply voltages without
special ordering.

• Each relay is equipped with an LED
that indicates four output status
conditions.

• Finger and back of hand protection
to IP40.

• Terminals are captive and supplied
in the open position.

-

• All RZ7’s can be surface mounted, rail
mounted, or mounted directly on our
family of CA7/CS7 or CA4/CS4 devices.

• RZ7 relays can be mounted in any
plane.

• Terminals, setting knob and LED’s are
all accessible from the front of the unit.

• RZ7 Timing Relays are very compact,
measuring approximately 1" x 3" x 4".

Description

Wye-Delta Timing Relay (Y)

When supply voltage is applied, output
contact Y closes for time period
period t, plus a fixed time period tu, (50­65ms) output contact Δ closes.

Repeat Cycle Timer (H) - (Flasher)

The Repeat Cycle Timer offers four different
operating characteristics within the same
relay. Depending on how the unit is wired,
cycles are initiated either by supply voltage
being applied or by a pulse from control
contact “S”. Regardless of the activation
method, each cycle may begin with a pause
or a pulse.

The RZ7-FSH3U relay sets the pulse and
pause durations equally. The RZ7-FSH3
allows individual time settings of pulse
and pause. Both relays offer multiple time
settings between 0.05s and 60h, selectable
in ten increments.

RZ7 Relative Scale Setting Knob

Series RZ7 Timing Relays have a “relative scale” setting knob numbered 0 to 1.0. ink about
this as 0 to 100% of the relay’s built-in time range. Example: To set an RZ7-FS timing relay
(with a 0.05 to 1 minute range) to activate after 25 seconds:

1) Divide the desired activation time (25 seconds)
by the maximum time limit of the relay (60
seconds).

25

÷ 60 = .416

2) Rotate the setting knob to just past the .4 mark.
