1 Product Description

1.1 General Description

The S664 frequency counter fits a 1/8 DIN standard cutout and is perfect for
tight spaces, extending only 3.24” (82mm) behind the panel.

The unit is UL listed. The unit is for indoor use at altitudes up to 2000m, tem­peratures between 0° and 40°C, and installation category III, pollution degree 2.

The counter is powered from 120 or 240 VAC.

One of four frequency ranges may be selected to measure from 1Hz to 35KHz.

The counter accepts pulses from different types of sensors, including Quadra­ture, CMOS or TTL circuits and PNP or NPN devices.

An optional 12 VDC (100mA) excitation output module can provide power for
external sensors.

2.1 Panel Installation

The S664 1/8 DIN counter requires a standard 1/8 DIN panel cutout of 1.77”
(45mm) high by 3.62” (92mm) wide. To install the counter into a panel cutout,
remove the clips from the side of the counter. Slide the counter through your
panel cutout, then slide the mounting clips back on. Press evenly to ensure a
proper fit.

2.2 Removing / Installing Option Modules

Shut power off before removing or installing any option modules

Couper le courant avant de retirer ou d’installer des modules optionnels

1. Remove module from case by inserting a screwdriver into tab slot opening at top of input
module. Apply pressure to release module from case. Repeat procedure for tab located on
underside of module and then slide module away from the case.

2. Refer to appropriate sections to congure switches or jumpers for proper operation.

Table 1 can be used to identify modules and their associated detail paragraph.

3. Install module by carefully aligning module edges with slots in case and pressing forward
until tabs (on top and bottom) engage.

Remove power before wiring option modules.

Coupez l’alimentation avant de raccorder les modules optionnels.

The AC power module allows the S664 to be
operated from standard 50/60 Hz line power.

The power module will be congured as 120
VAC or 240 VAC per markings on the back
panel. Ensure the input rating of the supply
matches your line voltage. The power supply
module has provisions for a hard-wire Range
Select. This control can be a switch, relay
contact or solid state device. Actuation is
immediate upon an active Low for at least

2.5ms to this terminal. The reset circuit is

independent of the power circuit.

Figure 7. Standard Input Module Default Settings

DIP switch SW1, gure 7, is used to set up the counter to conform to the electrical characteristics
of the sensor or signal being detected. Switch positions 1-3 congure channel B, while switches
4-6 congure channel A. These switches select bias (threshold voltages), low pass lter (enable/
disable) and sensor type (Sink or Source). Refer to the documentation that accompanied the
sensor for related information. The sensor can most likely be matched to one of the typical
switch settings shown in gure 8 and gure 8a.

Note: The input boards are designed so that selecting sourcing or sinking is based on the
type of sensor that is being used. If a PNP (sinking) sensor is being used, set the input
board for sinking also (switches 3 and 6 = OFF).

If channel B is not used, default settings for switch positions 1 through 3 should be selected.
Default settings are provided in Table 2.

The Input module also provides for a User input signal. On the S664, this input serves as a
secondary channel (Rate) hard-wired reset. This may be used, for example, to reset latched
alarm outputs that have been assigned to rate.

The S664 can accept inputs from many different sensors. The A and B chan­nels may be configured independently as shown in Table 2. Figures 8 and 8a
have examples of some typical sensors and the wiring connections that would be
used.

2.5 Quadrature Input Module

The Quadrature / Universal Input Module has two operational modes: Quadrature mode and
Standard mode. Quadrature mode is selected by positioning JP1 and JP2 on pins 1 and 2.
Standard mode is selected by placing JP1 and JP2 on pins 2 and 3 (see Figure 10 for details).

10

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

The Quadrature mode supports a wide range of encoders including the Simpson SE series.

While in Standard mode, this module works similarly to the Standard Input module, with the
added capability to selectively invert the A, B, and User input signals.

NOTE: If B channel is not going to be used, use the default switch settings
for SW1 positions 1 through 3.

Default settings are provided in Table 3. In both modes, the state of the User input signal can

be selected as active high or active low. DIP switch SW1 congures the counter to match the
specications of the accompanying sensor. When shipped from the factory, the counter is set

for X1 quadrature, as shown in Figure 10 and Table 3:

Figure 11. Wiring Encoder w/Excitaion Supply

12 VDC Excitation Module

The Excitation Module can supply 12 VDC at up to 100 mA for external sensors or encoders.
This excitation is isolated from the counter internal logic supply.

When using sensors or encod ers that do not have a signal return or imply a signal return that
is in common with the supply voltage, a common attachment that ties the excitation supply to
the logic input common may be required.

Examples of this appear in gures 8, 8a, 11 and 12.

Display Over Range: The displayed count is too
large for the counter to display. Since the internal
count buffer is much larger than the display, the
counter will maintain accurate frequency well

The S664 can measure frequencies ranging from 1.00 Hz to 35 KHz. The fre­quency scale is selected according to Table 4. The frequency range is selected
by using a wire or switch across the RESET and COMMON terminals on the
rear of the counter. The range prompt (scl 1) will toggle each time the contact is
made.

3.4 A/B Channel Inputs

The A channel input is a pulse source. This signal must be limited to under 35
KHz. This corresponds to a minimum pulse width of 28.57 microseconds. The
signal does not need an even duty cycle (On vs. Off time) as long as a minimum

(high or low) of 1 microsecond is maintained (See figure 15).

The B Channel acts as a direction control. If the B input is in the active state,
frequency will be displayed as a negative number. When using the quadrature
input card (in quadrature mode), A and B encoder signals are translated to Pulse
and Direction signals internally.
