Montrose, CA.... The new Micro/sys OPTO104 expansion card accommodates eight industry-standard digital or analog OPTO plug-in modules plus any PC/104 CPU or I/O cards that are needed to make a rugged, compact industrial controller. Any combination of digital or analog I/O modules can be plugged into this 4.53” x 6.50” EPIC sized board that is designed for rugged environments and extended temperature ranges of -40 to + 85 degrees C operation. These features provide a solid platform upon which I/O intensive systems can be built. 
When the application demands even more I/O, up to four of the OPTO104 boards can be connected together in a slave configuration using a 26-wire ribbon cable. This makes available 32 slots for OPTO 22 G4 modules for AC or DC digital I/O, and/or Grayhill G5 modules for analog I/O. All of these modules offer opto-isolation up to 4000 volts. 
Additional system-level features of the OPTO104 include watchdog timer, rotary encoder input, onboard temperature sensor, and interfaces for a character-based LCD, keypad, CAN bus, and Dallas iButton Probe. These features, when combined with the users’ favorite off-the-shelf plug-on PC/104 CPU boards, provide the unique system features required in industrial applications.  
The board operates at 5V ± 5%, or, a selection of DC-DC converter options allows an input voltage range from 9V to 75V. A user-selectable jumper can bleed off common mode leakage current to the negative inputs or to safety ground in order to reduce susceptibility to ESD. On-board or off-board contrast adjustment for the character LCD is also provided. A flexible I/O base address range and 16 bit pass-through connector makes the OPTO104 an ideal board for high-voltage isolation applications. 
The OPTO104 is $375 in single quantities. Significant OEM discounts are available. In addition, Micro/sys offers cables, breakout boards and related products that can minimize prototype efforts and improve time to market.
