when 0 % output frequency is set to a frequency other than

0 Hz.

■ 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

Totalized pulse count: 0 – 99999999; Blinks at overflow.

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.

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

output pulse; remains on at 30 Hz or higher frequencies.

INPUT SPECIFICATIONS

■ DC Current: 0 – 50 mA DC; shunt resistor attached to

input terminals (0.5 W)

Operational range: 0 – 70 mA DC (with 100 Ω/0.5 W)

Default setting: 4.0 – 20.0 mA DC

■ DC Voltage

•Code S1: -1.00 – +1.00 V DC

Operational range: -1.15 – +1.15 V DC

Minimum increment: 10 mV

•Code S2: -10.0 – +10.0 V DC

Operational range: -11.5 – +11.5 V DC

Minimum increment: 100 mV

•Code S3: -30.0 – +30.0 V DC

Operational range: -34.5 – +34.5 V DC

Minimum increment: 100 mV

Note: 100 % input must be larger than 0 %.

Default setting:

Code S1: -1.00 – +1.00 V DC

Code S2: -10.0 – +10.0 V DC

Code S3: -30.0 – +30.0 V DC

OUTPUT SPECIFICATIONS

100 % output frequency must be higher than 0 %.

Note: Minimum increments is 1/1000 of each frequency

range.

• Open Collector: 50 V DC @ 50 mA (resistive load)

Frequency range: 0 – 10 pulses/hour through 10 kHz

Saturation voltage: 0.6 V DC

■ Voltage Pulse

Frequency range: 0 – 10 pulses/hour through 10 kHz

Lo level: ≤ 0.5 V

Hi level: 5 – 24 V ±10 %

(selectable in 1 V increments)

Load resistance: 5 kΩ minimum

■ AC/DC Switch: 120 V AC/DC @ 200 mA (resistive load)

Frequency range: 0 – 10 pulses/hour through 10 Hz

On resistance: 3 Ω

Rise time: 5 msec.

Sink time: 3 msec.

■ RS-422 Line Driver Pulse

Frequency range: 0 – 10 pulses/hour through 10 kHz

Conforms to EIA/TIA-422-B

OUTPUT PULSE WIDTH

■ DUTY RATIO 50 % (approx.)

The duty ratio remains at 50 % (approx.) even when the

output frequency changes.

■ ONE-SHOT OUTPUT

The output pulse width varies by 10 % of the preset value.

Selectable from 1 msec. up to 10 sec. (50 msec. – 10 sec.

for AC/DC switch).

For 10 kHz and a part of 1 kHz ranges, the one-shot output

is not selectable. Choose 50 % duty ratio for such cases.

If the preset value is wider than the cycle at 115 % output,

this unit does not function properly related ITEM number

blinks.)

[Example] 0 % output frequency = 50 Hz

100 % output frequency = 100 Hz

115 % output cycle = 9.3 msec.

The output pulse greater than 9.3 msec. is not appropriate.
