The Opto Isolation module attaches directly onto the BaseBoard card inside the computer and provides protection from damage when power is off to the BaseBoard but inputs from external equipment are active (a potential situation when interfacing to the RL indicators). The Opto module provides 2500v optical isolation protection and can handle over-voltage inputs and floating grounds. The Opto Isolation INPUT modules are about 2” x 3” with a 40 position socket connector and a 50 pin header connector. The module plugs onto the current 40 pin connector of the BaseBoard. The 50 pin header of the Opto Isolation INPUT module is then used to connect to a ribbon cable.

Without the Opto-Isolation INPUT module, the cable from the BaseBoard to the RL Indicator is 40 conductor with:

• A 40 position socket connector on one end to connect directly to the BaseBoard
• A DB37 connector on the other end to connect to the RL-520 indicator.

With the Opto Isolation INPUT module, the ribbon cable from the RL indicator changes.  The cable is now 50 conductor instead of 40.
The 50 conductor cable has:

• A 50 position socket connector on one end to connect to the Opto INPUT module
• A 50 position socket connector on the other end to connect to an RL Adapter
• The RL Adapter performs the following tasks
• Converts 50pin BaseBoard to DB37 pin RL-520 Connector
• Provides proper wiring of data and status signals
• Includes circuit with current limiting protection

Scientific Solutions offers the Opto Isolation module and a Cable & Adapter kit that can be purchased directly from Scientific Solutions and installed in the field.  With these items, the customer has everything they need to install the Opto Isolation INPUT module and cabling to protect their BaseBoard product from damage.  

• The BaseBoard / ISA has four ports, labeled P1 thru P4. 
• Most cement mixing installations only use two of the four ports.
• Normally one port per scale indicator, and most installations have two scales
  
• So for the typical installation, you will need two Opto Isolation modules with cables & adapters.
• Qty=2, of Opto Input Module
• Qty=2, of Cable & Adapter Kit
  

Currently, Scientific Solutions has a Cable & Adapter kit for the Rice Lake Indicator Model: RL-520.

If you require a Cable & Adapter kit for a different indicator, please contact Scientific Solutions to discuss your needs.
