THE Union Switch & Signal Microlok Object Controller is a programmable microprocessor device used for vital or non-vital control and indication of lineside devices such as points, signals, or other equipment. The device was launched by US&S at the AusRail exhibition in Brisbane in November 2006 as a low cost vital/non-vital logic controller with variable inputs and outputs. It offers both ethernet and serial link communications port options and provides an integrated TCP/IP stack to allow compatibility with commercial communications products. The Object Controller has a number of potential applications including the monitoring and control of hand-thrown or powered points, intermediate signal vital logic and remote device monitoring, or movable bridge alignment and locking.The Object Controller has been designed to fit into a typical lineside location box, significantly reducing the amount of space required for its installation.
