PULSE STRETCHING UNIT
Description
Function :
To stretch the input pulse received from AC Proximity Switch, which will be useful for further Processing. In fast operating systems / machines, the sensing target comes in sensing zone of Proximity Switch for very short duration. Control system like PLC is unable to recognize such a short duration pulse. With the help of Pulse Stretching Unit, Short duration Pulse can be extended from mSec to seconds, which makes further processing possible.
| Supply Voltage 110V AC or 230V AC, 50 Hz. |
| Input from AC Proximity Switch. Maximum no. of inputs are 6. |
| Solid state Output suitable for PLC Operation. |
| Adjustable Delay Range. |
| Output logic (NO OR NC) selectable by link. |
| Sheet Metal, IP-55 grade Enclosure suitable for field or wall mounting. |
| Supply | : 110V AC or 230V AC, 50Hz |
|---|---|
| Input | : AC type Proximity Switch. Proximity switch Supply is same as Unit Supply |
| No. Of Inputs | : Max. 6 |
| Output | : Solid State, suitable for PLC application. NO load current < 2 mA. Ilmax = 400 mA |
| Output Logic | : Same as per the Input Proximity Switch. Reverse logic can also be selected by link selection |
| Delay Range | : 250 msec to 10 sec. Adjustable for individual channel |
| Delay Logic | : The logic for delay is “OFF Delay”, i.e. Actuation is instantaneous but de-actuation is with delay |
| Enclosure | : Sheet Metal, IP-55 Grade, suitable for field or wall mounting |
To stretch the input pulse width for detection by PLC.
