32 Line DOUT Tortoise Adapter
Product Description
32 line tortoise adapter (16 tortii) for Tortoise by Circuitron) plugs onto a classic DOUT CMRI output card. Each line is pulled up through a 680 ohm resistor, 12V power is applied through 5mm screw terminals and the tortoise is controlled by grounding one or the other line through the DOUT. See Dr. Chubb's CMRI 2012 Applications Handbook Volume 1- System Extensions Chapter 7 pages 7-8 through 7-11. Dr. Chubb's books are available at https://www.jlcenterprises.net/
Input is via female Molex 0.156 connectors, output pads are provided for 0.156 Molex and 3.5mm screw terminals, your choice.
This board is somewhat expensive Assembled and Tested item due to the labor involved in installing the many resistors, so it is a great "Do it Yourself" project as the parts cost is well South of $20. We offer the board bare and Assembled & Tested. .5" Resistor spacing allows for traditional 1/2 W carbon film resistors, although the carbon film resistors you buy today fit in the .4" footprint commonly associated with 1/4W resistors.
Also see our 8 Line CMRI Tortoise Adapter for smaller applications! They can combined with our other CMRI adapters as needed.
