PRS1 INPUT CIRCUITS, SENSOR CONNECTIONS & CONFIGURATION SWITCH SET-UP
The Model PRS1 Speed Switch uses the circuit shown on the right. The
circuit uses a comparator amplifier connected as a Schmidt trigger circuit to
convert the input wave form into the pulse form required for proper circuit
operation. Three set-up switches are used to configure the input circuit to accept
signals from a wide variety of sources, as follows:
S1 - ON: Connects a 1 K pull-down resistor for sensors with sourcing output .
(Maximum sensor output current is 12 mA @ 12 V output.)
S2 - ON: Sets bias of input to trigger at V IL = 2.5 V, V IH = 3.0 V; for logic level
signals.
OFF: Sets the bias of input to trigger at V IL = 0.25 V, V IH = 0.75 V; for
increased sensitivity when used with magnetic pickups.
S3 - ON: Connects a 3.9 K pull-up resistor for sensors with current sinking
output. (Maximum sensor current is 3 mA.)
OTHER CHARACTERISTICS & SPECIFICATIONS
Maximum Operating Frequency: 10 KHz with maximum pulse width ON
and OFF times of 50 μsec.
Maximum Input Voltage: Pin 7 (Input) may be driven from an external voltage
up to ±90 V provided S1 and S3 are “OFF” to disconnect internal load
resistors. (Maximum Input Voltage with S1 “ON” is ±16 V)
Input Impedance: With S1 and S3 “OFF”, the resistive input impedance
exceeds 1 Megohm, as long as Pin 7 voltage is greater than zero and less
than +12 V.
Paralleling With a Counter and/or Rate Indicator Inputs: The PRS1 can be
operated from a common sensor with current sinking output that is also used
to drive the input of a Counter or Rate Indicator. Connect Pin 8 to the
Common Terminal and Pin 7 to the Input Terminal of the Counter or Rate
Indicator; set S1 and S3 “OFF” and S2 “ON”. DO NOT PARALLEL
CONNECT THE +12V OUTPUTS (Pin 9) OF PRS1 UNITS WITH THE
+12V OUTPUTS OF COUNTERS, DITAKS, OR OTHER PRS1 OR PRA2
UNITS. These units have regulated supplies that will not load-share. Multiple
inputs cannot be operated from sensing switches, 2-wire proximity sensors,
or magnetic pickups.
CONNECTIONS & CONFIGURATION SWITCH SET-UP FOR VARIOUS SENSOR OUTPUTS
MAGNETIC PICKUPS
RECOMMENDED RULES FOR MAGNETIC PICKUP CONNECTIONS
1. Mount the PRS1 in a relatively “noise-free” environment, away from motor starters,
control relays, or other sources of electrical interference.
2. Use 2-wire shielded cable for magnetic pickup signal leads.
3. Never run signal cable in conduit, troughs, or cable bundles with power carrying
conductors.
4. Connect the shield to the common Terminal “8” at the input of the PRS1. DO NOT
connect the shield at the pickup end, leave it “open” and insulate the exposed shield to
prevent electrical contact with the frame or case. (Shielded cable, supplied on some
RLC magnetic pickups, has open shield on pickup end.)
SENSORS WITH CURRENT SINK OUTPUT (NPN O.C.)
RLC SENSOR MODELS:
ASTC, LMPC, PSAC, LSC, RPGC, RPGB, RPGH, RPGQ, HESS, etc.
SENSORS WITH CURRENT SOURCE OUTPUT (PNP O.C.)
2-WIRE PROXIMITY SENSORS
RLC SENSORS WITH -EF OUTPUT
RLC SENSOR MODEL: LMPEC
A.C. INPUTS FROM INVERTERS, A.C.
TACHOMETERS GENERATORS, ETC.
R - Resistor to limit input current to 5 mA peak
C - Filter cap required when input A.C. has “ringing”
characteristics as with inverters.
A.C. Power sources exceeding 50 V output
should be coupled with an isolation transformer.
INPUT FROM CMOS OR TTL

SWITCH CONTACT INPUT
The addition of two external resistors and a capacitor
allows the PRS1 to be operated from input signals
generated by a switch contact. The external RC network
forms a Low-Pass Filter which operates in conjunction
with the hysteresis of the input circuit to “De-bounce” the
Switch Contact signal.
Use of the Low-Pass RC Filter places a high-speed
restriction on the circuit, and it cannot be used at
frequencies of more than 200 to 300 cps. However, Switch
Contact input is normally limited to low speed operation,
so this does not impose a serious restriction.
