Expansion unit

Response time

23 µs (S-HSPD) / 50 µs (HSPD) / 250 µs (FINE) /500 µs (TURBO) / 1 ms (SUPER) / 4 ms (ULTRA) / 16 ms (MEGA) / 64 ms (TERA)

Number of control outputs

1

Number of external inputs



Light source LED

Transmitter side: Red, four-element LED (wavelength 660 nm)

Control output

Open-collector, 30 V or less 100 mA or less per output,
100 mA or less total for 2 outputs (when used as a solitary unit) / 20 mA or less (when used as an expansion unit)
Residual voltage: 1.4 V or less (output current 10 mA or less) / 2 V or less (output current 10 to 100 mA)

External input

Input time 2 ms (ON) / 20 ms (OFF) or longer

Unit expansion

Up to 16 units (17 units connected in total including the main unit).
However, each dual output type will be treated as two expansion units.

Protection circuit

Protection against reverse power connection, output overcurrent, output surge, and reverse output connection

Mutual interference prevention

S-HSPD/HSPD 0 units, FINE 4 units, TURBO/SUPER/ULTRA/MEGA/TERA 8 units
(The mutual interference prevention values are twice those shown here when Double is set.)
