1 Product Description

1.1 General Description

The S661 rate 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. The nonvolatile EEPROM retains all
programming and count information when power is removed or interrupted.

Display scaling, preset values and all menu functions are easily programmed from the
front panel, following easy-to-use word prompts. Front panel reset disable and pass­word lockout protection features guard against unauthorized or accidental changes.

The counter accepts count rates up to 30 kHz and pulses from different types of sen­sors, including Quadrature, CMOS or TTL circuits and PNP or NPN devices.

The optional, field-replaceable single/dual relay module enhances the counter from a
passive display device to an integral control element for your application. The counter
has latching, boundary or timed (0.01 to 599.99 seconds) output modes.

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

Figure 7. Standard Input Module Default Settings

DIP switch SW1, figure 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 config­ure channel B, while switches 4-6 configure channel A. These switches select bias
(threshold voltages), low pass filter (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 figure
8 and figure 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 (switched 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 S661, this input per­forms a Display Hold. While active, the rate value shown on the display is “frozen.”
Internal measurements and output controls continue to operate.

The S661 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). 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 A, B, and User input signals. The Input
module also provides for a User input signal. On the S661 this input serves as a Dis­play Hold. While active, the rate value shown on the display is “frozen.” Internal mea­surements and output controls continue to operate.

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.

11

Find Quality Products Online at: [email protected]

www.GlobalTestSupply.com

In both modes, the state of the User input signal can be selected as active high or ac­tive low. DIP switch SW1 configures the counter to match the specifications of the ac­companying sensor. When shipped from the factory, the counter is set for X1 quadra­ture, as shown in Figure 10 and Table 3:

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 encoders 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 figures 8, 8a,
11 and 12.

4.2 A/B Channel Options (Input Setup)

The next category in the Programming Mode is the “Input Setup.” Here you can adjust
the A and B channels to the appropriate count modes.

The A channel input may be selected as an Up, Down, Quadrature or Reverse
Quadrature* input.

As an Up channel, pulses applied to the A input are added to the display. In Down
mode, subtraction occurs. Note that when using Quadrature inputs, appropriate hard­ware (jumper) settings may be needed.

* The Reverse Quadrature input allows the user to reverse the count direction of the
encoder in software instead of having to rewire/remount the encoder.

memory, and press again to proceed to the next parameter, Chan B Mode.

The B channel may be set as Up, Down or Direction. In the direction mode, the B
channel is no longer a count source, but controls the count direction of the A channel
input. This state control works as an ‘exclusive-or’ with the channel A direction. Thus,
if B input is in the ‘Down’ state and A channel is set to Down, pulses at the A input will
increment count.

Table 9. Rate Example
The input frequency can be linearly scaled using the Scaling Multiplier, Offset and
Decimal Point. The rate channel has an offset value as well. To illustrate, the follow­ing example will be used:

1) Multiply Input Frequency by implied Mode multiplier
10000 x 1= 10000

2) Multiply by user-specified Scale:

3) Discard all digits to right of decimal place:
(If number is larger than six digits, it will not fit in the display)
5000

4) Apply the user-specified DP location:

50.00

5) Add user-specified Offset location:

250.00 - 100.00 = 150.00
(That is what will be seen of the display)
The following notation may be used to describe this behavior:
Display = INT [Fint x Scale] DP + Offset

delay may be between 0.01 and 599.99 seconds

The output w ill activate when the specified value is

encountered (SP1 for output 1, SP3 for output 2).
If a timing period is in progres s, a new trigger does
not occur. This is referred to as a non­retriggereable timer.

A RESET will cancel the timed out

The latch mode activates an output when a ‘trigger’
or set point is reached.

The output will activate when the value is

4.5 Set Point Parameters (Set Point Setup)

The S661 has four set point parameters and an Offset Value.

SP1 and SP2 are used only with Output 1, and SP3 and SP4 are used only with Out­put 2.

The SP1 and SP3 parameters are used as Latched or Timed “trigger” values. When a
Boundary Output is selected, SP1 and SP3 become the low boundary value.

The SP2 and SP4 parameters are used as high boundary value or ‘turn-off’ values
when used with other alarm types (i.e. latched until SP4).

The values for all set points are -99999 to 999999. The decimal point will appear ac­cording to the current decimal point setting.
