Input/Output

Control Output

Open collector, 30 VDC or less, N.O./N.C.
When used as a solitary unit: 100 mA or less for 1 output; 100 mA or less in total for 2 outputs; When expanding with multiple units: 50 mA or less for 1 output
Residual voltage NPN: 1.4 V or less (output current: 10 mA or less)/2 V or less (output current: 10 to 100 mA)

External Input

External Set/Laser OFF/Zero Shift/Hold Reset/Gyro Alert RST selectable
Short circuit current - NPN: 1 mA or less
Input time: 3 ms or more ON, 20 ms or more OFF (25 ms or more ON, 25 ms or more OFF only when External Set is selected)

Unit Expansion

Up to 8 expansion units possible (including main unit, a total of 9 units connected)
However, up to 16-unit expansion is possible when the LR-XN10 is used for expansion with the NU Series.

Protection Circuit

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