Input pulse sensing: Capacitor or DC coupled

Averaging non-uniform input waveforms: Input pulses are

divided and then multiplied so that the output pulses are

averaged.

Low-end cutout: 0 Hz equivalent output is forced during the

low-end cutout; -15 to +115 % adjustable; deadband 1 %

■ DISPLAY

LED: 8 mm (.31”) 7 segment, red

Number of display digits: 4 digits for DATA display; 2 digits

for ITEM display

Scaling: -9999 to 9999

PV indication: Input signal in engineering unit

Overrange indication: LEDs blinking

Power saving mode: Displays turn off if the keys are

untouched for a preset time period

Status LEDs: Red; the PL1 turns on with negative polarity,

the PL2 with programming error and the PL3 with low-end

cutout.

Input LED: Red; the PL4 blinks in synchronization with the

input pulse.

Note: LED response takes time when the input decreases

from a very high frequency to a low frequency.

INPUT SPECIFICATIONS

Sensor excitation: 5 – 24 V DC ±10 %; 1 V increments

(default setting: 5 V): Activated / deactivated via front

control keys

Max. current (mA): 600 mW / Excitation voltage (V); 120 mA

at 5 V, 50 mA at 12 V, 25 mA at 24 V

Current limit protection: Approx. 330 mA at shortcircuit

(Overcurrent will appear at shortcircuit. If the device cannot

withstand the overrcurrent, be sure to turn off the sensor

excitation for safety before wiring excitation to the device,

and then turn it on after confirming the connection.

The sensor excitation is factory set to ON. Turn it off when

not used.)

Frequency ranges: 0 – 0.01 Hz through 100 kHz (up to 10 Hz

for mechanical contact)

Minimum pulse width requirements: 4 μsec. for both ON and

OFF (Hi and Lo) except for the mechanical contact (40

msec. for ON and OFF)

Note: Minimum increments of 0 % and 100 % input

frequency are 1/1000 of each frequency range.

■ Open Collector, Mechanical Contact

Detecting power/current: Approx. 15 V DC @ 1.8 mA

Detecting levels: ≤ 200 Ω / 2.5 V for ON;

≥ 100 kΩ / 4.0 V for OFF

■ Voltage Pulse

Waveform: Square or sine

Input impedance: 10 kΩ minimum

Input amplitude: Min. 0.5 Vp-p, max. 100 Vp-p

Max. voltage between input terminals: 50 V

• DC Coupling

Detecting levels (Manual)

Max. DC offset voltage: 9.9 V

Or 3 steps automatic setting available.

Automatic:

(Recommended input pulse levels: 2 V - 4 Vp-p, max. DC

offset voltage: 1.2 V)

(Recommended input pulse levels: 4 V - 12 Vp-p, max. DC

offset voltage: 2.2 V)

(Recommended input pulse levels: 12 V - 50 Vp-p, max.

DC offset voltage: 5.5 V)

(ITEM No. blinks when setting error)

• Capacitor Coupling

Detecting levels

Max. DC offset voltage: 26 V

Or 1 step automatic setting available.

With the capacitor coupling, sine or similar waveforms

below 20 Hz and/or 1 Vp-p cannot be detected. The

capacitor coupling can be used when the detecting levels do

not match with DC coupling, such as when the DC offset

voltage is ≥ 9.9 V or ≤ 26 V.

■ Two-wire Current Pulse

Input resistance: Receiving resistor 100 Ω

Input range: 0 – 25 mA

Detecting levels: ≥ 13.6 mA for Hi; ≤ 7.2 mA for Lo

■ RS-422 Line Driver Pulse

Receiver: Conforms to RS-422

50V max.
