Description | Function | |
---|---|---|
1 | Power indicator (Red LED) |
Lights up when the power is ON. |
2 | Output indicator (Red LED) |
Lights up when the output is ON. |
3 | Sensor 1 output indicator (Red LED) |
|
4 | Sensor 2 output indicator (Red LED) |
|
5 | Sensor signal input selection switch | Selects the output operation. NORM.: The output is ON when the sensor signal input is Low. |
6 | Sensor 1 output operation mode switch | Selects the output operation. NORM.: The output is ON when the sensor signal input is Low. |
7 | Sensor 2 output operation mode switch | |
8 | Sensor signal input indicator (Red LED) |
Indicates the state of the sensor signal input. The operation differs according to the mode set with 5 Sensor signal input selection switch. INV.: Lights up when the sensor signal input is High. NORM.: Lights up when the sensor signal input is Low. |
9 | External synchronization input indicator (Red LED) |
Indicates the state of the external synchronization input. Lights up when the external synchronization input does not disable the output. |
10 | External synchronization operation mode switch | Selects the operation of external synchronization. NORM.: The output is neglected when the external synchronization input is Low. |
11 | Gate/Edge trigger operation mode switch | Selects Gate trigger or Edge trigger. :Effective at the instant the external synchronization input is applied. :Effective over the period for which the external synchronization input is applied. |
12 | Timer period selection switch | Selects the timer period. 10 sec.: Variable from 0.4 sec. approx. to 10 sec. approx. |
13 | Timer operation mode switch | Selects the timer operation. |
14 | Timer operation mode switch | Set the timer period. |
15 | Terminal block | ー |

<Function> | Neglects short output signals. |
---|---|
<Application> | As only long signals are extracted, this function is useful for detecting if a line is choked or for sensing only objects taking a long time to travel. |
<Function> | Extends the output signal for a fixed period of time. |
---|---|
<Application> | This function is useful if the output signal is so short that the connected device cannot respond. |
<Function> | Outputs a fixed width signal upon sensing. |
---|---|
<Application> | This function is useful when the input specifications of the connected device require a signal of fixed width. Of course, it is also useful for extending a short width signal to a desired width. |
Various other applications are possible.
Selection switch and timer operation
Timer period: T =Switchable, either 40 ms approx. to 1 sec. approx., or 0.4 sec. approx. to 10 sec. approx.
The output is disabled when the external synchronization input is Low [mode selection switch on NORM. (Note)] or is High [mode selection switch on INV. (Note)].
Note: | SinceNPS-C7 is not incorporated with the selection switch, the output is disabled only when the external synchronization input is Low. |
---|
The sensor signal is judged at the instant the external synchronization input rises up or falls down. This sensor is ideal for cap presence detection that would have required two controllers in the past.
Example: Detecting presence of cap on bottle

|
Note: | As the output time‘t’is only 5 μs approx., extend it by using the OFFdelay timer or the ONE SHOT timer. |

The short-circuit protection plate is attached to terminal No. 1 to prevent AC short-circuit. Flip the plate up, connect the wire to terminal No. 1, and then flip it down. (The short-circuit protection plate is attached at the time of shipment from our factory.) |
The short bar saves wiring when a common power supply is used for the AC supply terminal and the load supply of the relay contact output.
(The short bar is attached between the terminal Nos. 1 and 2 at the time of shipment from our factory. To use a separate power supply for the output relay, make sure to remove it.)
