contact inputs). The third range is input to the preamplifiers
on channels 1 and 2 (for low level pulse inputs between 50 mil-
livolts and 10 Volts peak to peak). The DSM connects inputs to
the Infi 90 system without separate converters.
You can select individual voltage and response time with jump-
ers on the module to configure each input. Selectable response
times (fast or slow) allow the Infi 90 system to compensate for
process field device debounce time.
The slave provides 16 bit resolution in the input channels for
frequencies up to 50 kilohertz. It makes high resolution mea-
surements of low frequency signals at selected rates for periods
between 20 microseconds and 655 x 103 seconds. The slave
can count the number of rising or falling edges of input signals
and measure the time between the pulse edges. Refer to
for more information.
INSTRUCTION CONTENT
This manual has eight sections.
Is an overview of the DSM: Features, description and
specifications.
Explains the module operation and input circuitry.
Describes precautions to observe when handling DSM modules
and setup procedures required before module operation. This
section also discusses switch and jumper settings, and instal-
lation procedures.
