Model IO.40/IO.45
|
The Models IO.40 and IO.45 provide the required input power regulation and interface connections for the Compact Remote Station Model 45.50. The IO.40 module is designed for the analog and the IO.45 module for the digital version of the Compact Remote Station, respectively. The features of the IO.40/IO.45 module include fused transient protection for power, reverse polarity protection for input power, and optionally, transient protection for calibration coil connections. Up to three signals from external VCO's can be multiplexed by the IO.40/IO.45 module for connection to the Model 46.32 VCO/multiplexer. The Models IO.40/IO.45 need ±12 V, while the Models IO.40-1/IO.45-1 need only +12 V to operate.
