RR-CirKits OI-IB-8 8-line Input Opto-Isolation Board

RR-CirKits OI-IB-8 8-line Input Opto-Isolation Board

This board is normally used for block detection on three rail layouts. This version of the board includes internal current limiters. Useful anyplace that an external voltage needs to be monitored. (5V-20V AC-DC-DCC).

All RR-CirKits Tower Controller I/O modules are designed to either be plugged directly into the TC-64, or else mounted in Tyco 3-1/4" Snap-Track® mounted to the bench work and connected with short ribbon cables. (Snap-Track® is a plastic channel designed to mount PC cards to a chassis, not something to run trains on.) This I/O module is equipped with three connectors to facilitate these connection options and allow for pass through wiring.

OIB-8 (8 line Opto Isolator Board)

The OIB-8 board contains two 8 position input connectors. Each individual input pair has a position to mount a series limiting resistor and individual indicator LEDs. Each input may be connected as AC, or polarity sensitive DC.

The OIB-8 may be used any place that requires isolation between an input circuit and the TC-64.

Some examples are train detection by isolated rails such as is commonly used in three rail layouts or overhead powered tracks. Another use is to monitor incandescent signal lamps and translate their state into TC-64 commands.
