ABOUT 3563
The Model 3563 is a single-width CAMAC module providing 16 or 32 channels
of general-purpose analog signal monitoring with open circuit detection capability as
well as 16 or 32 channels of input multiplexing. It is used with the Model 3518 16-bit
Scanning A/D Converter Host module. The 32-channel version does not include inputfilters. The 16-channel version includes a 2-pole, lowpass filter per channel. When
enabled from the Dataway, the 3563 switches apositive 10 volts resistance path onto
the SOURCE leg of the incoming temperature signal and a negative 10 volts resistance
path onto the RETURN leg. Reading the channel's new signal value with the 3518
verifies that thefield wiring is intact and determines its resistance value. Plus and
minus 10-volt sources are applied to the field wiring through precision, 100
kilohm resistors (one resistor per leg).
