Red Lion LEGEND - Manual (Page 45)

SPECIFICATIONS
1. DISPLAY: 2x8, 0.3" (7 mm) high characters, negative image transmissive
LCD, with yellow/green or red LED backlighting.
2. POWER:
AC Operation: 115/230 VAC ±10%, 50/60 Hz, 10 VA, switch selectable.
DC Operation: +12 VDC ±20% @ 250 mA.
3. MEMORY: Non-volatile memory retains all programming information.
Count and Preset values are written to non-volatile memory when power is
interrupted. All other programming parameters are written to memory when
programming mode is exited. If power is removed while in the programming
menu’s, the parameters are restored to previously saved settings.
Data Retention: 10 yrs. minimum.
4. SENSOR POWER: +12 VDC ±25% @ 100 mA.
5. INPUTS A and B: DIP Switch selectable to accept count pulses from a
variety of sources including switch contacts, outputs from CMOS or TTL
circuits, and all standard RLC sensors.
LOGIC: Input trigger levels V

Debounce: Damping capacitor provided for switch contact bounce.
Limits count speed to 50 Hz and input pulse widths to 10 msec
minimum.
MAGNETIC PICKUP:
Sensitivity: 200 mV peak.
Hysteresis: 100 mV.
Input impedance: 3.9 K
W @ 60 Hz.
Maximum input voltage: 50 Vp
Note: For magnetic pickup input, the sink/source DIP switch must be in
the SRC position.
6. RATE ACCURACY: +0.01%.
7. RATE MINIMUM INPUT FREQUENCY: 0.01 Hz.
8. MAXIMUM COUNT RATE IN KHz:

Notes:
1. Maximum count rates given are for Process counter set for Auto reset with
the auto cycle preset set to an equivalent of 100 count pulses or greater.
With auto cycle presets less than 100 count pulses, with Count SF = 0.5000
and Count Scale Multiplier = X1, would be 50.
2. Maximum count rate given for X2 & X4 count modes are given for 50%
duty cycle signals and Quad signals with 90º phase shift.
* - Inputs’ A & B count rates summed.
