The Stamp PLC (Program Logic Controller) is sized for automating small machines. Specified by Parallax and designed by Lawicel HB of Sweden, this product represents our combined expertise to answer to a frequent request from our customers. A 24-pin BASIC Stamp module is required and sold separately.
Features:
- Complete Javelin and BASIC Stamp® code support
- Safe 24V industrial control in a DIN rail package
- 10 digital inputs; 8 digital outputs; 4 analog inputs provides control flexibility
- 4 Analog Inputs. Each channel can be independently configured as 4-20mA, 0-5 VDC, -/+ 5 VDC, -/+ 10 VDC.
- Front Panel LEDs indicate the status of all ten inputs and all eight outputs via a light-pipe array.
- 8 Digital Outputs are optically isolated, electrically and thermally protected.
- 10 Digital Inputs. Eight of these inputs are grouped together using an on-board shift register. BASIC Stamp modules and the Javelin Stamp module have built-in commands to read these with ease. The remaining two inputs are read directly by the Stamp. All inputs are optically isolated.
- Heavy-duty power supply has built-in noise protection.
- RS-232 Serial Port Once programming is completed, the on-board serial port can be used to send and received data at any baud rate between 300-50K Baud.
- Product includes jumpers for A/D converter, serial cable; power supply and A/D converter sold separately.
- 24-pin socket accommodates any 24-pin BASIC Stamp module. This means that this PLC can do virtually anything that your chosen BS2 module can perform: logic functions, numerical computation, conditional branching, even non-volatile memory for data-logging.
