System Interface I/o Board

The TIDT control system provides a very flexible configuration. The system is easily integrates with other systems, such as lighting, heating, air conditioning, alarm reporting, etc. For interfacing with systems such as those listed above, however, in most cases a dry contact with output is required, and optical isolation is required on many inputs. Part #81147, system interface I/O board, provides a form C contact output and accepts a dry contact input for 16 I/O points. Part #81151, system interface I/O board, provides 16 I/O points. The outputs are form C contacts and the inputs are all optically coupled inputs. Therefore, the integrity of the MTI supply system can be maintained completely isolated from other systems. As with all other components of the MTI system, the system interface boards are address configurable. The address of the inputs and outputs of the board are set by the dip switch on the 81147/81151 board. Due to the form C contacts on the outputs of part #81147, a variety of external connections may be made. Please note that each individual output is completely isolated from all other outputs. Therefore, there is an ease of system integration.
