The Stamp Controller Interface allows the BASIC Stamp® microcontroller to connect directly to industrial type digital I/O control boards produced by Opto22, Grayhill, Allen-Bradley, and others that accept 0-5 VDC voltage control levels. These optically isolated modules are ideal for interfacing microcontrollers to the real world, and are more reliable by providing proper isolation. The Stamp Controller Interface accepts the BS1 and all 24-pin BS2 modules, and has a parallel port connection for monitoring status of I/O pins. A clever driver/resistor configuration allows the user to mix and match up to 16 inputs and outputs in any configuration.
Features:
- Host serial/parallel ports for programming the BS1-IC, BS2-IC, BS2e-IC, BS2sx-IC, BS2p24-IC and BS2px24-IC respectively
- Parallel port for monitoring
- Opto-isolated I/O pins for protection
- Prototype area for connection of peripheral devices to BASIC Stamp I/O pins
- 2.1 mm power plug
- +5 VDC 1000mA power output for digital I/O controller
- Reset button
- 50-pin IDC header
