Sensor Amplifier
*1 The input time is 25 ms (ON) / 25 ms (OFF) only when external calibration input is selected.
*2 Increases 30 mW (1 mA) for HIGH SPEED Mode
*3 When using expansion units, the working ambient temperature will change according to the following conditions.
Always install on a DIN rail (installed on the metal plate) and keep the output current to 20 mA / unit or less.
1 or 2 units connected: - 20 to + 55°C; 3 to 10 units connected: - 20 to + 50°C; 11 to 16 units connected: - 20 to + 45°C
When using the 2 output type, one unit is counted as two units.
*4 When connecting nine or more expansion units, ensure that the power voltage is 20 V or more.
*5 It increases by 15% when connected to the LV-NH100/NH110/NH300. It dose not include the power consumption of the load.
Power consumption when expansion units are connected is the total power consumption of each amplifier unit.
Example: When one main unit (LV-N11N) is connected to 2 expansion units (LV-N12N) and they are used with LV-NH100 heads in HIGH SPEED mode.
(1.15 x 860mW x 1) + (1.15 x 860mW x 2) = 2967mW max.
*6 Use with the over current protection device which is rated 30 V or more and not more than 1 A.
*7 When an amplifier is connected to the LV-NH100,LV-NH110 or LV-NH300 and used in HIGH SPEED mode, the power consumption is maximum. (989mW for NPN or 1127mW for PNP)
*8 Response time will be doubled from the normal response time when Double is set.
