3-wire Acceleration and Temperature Sensor
Such a sensor has two outputs and therefore occupies two input channels of a
DYN module. The acceleration and temperature signals are allocated to
channels in separate channel pairs so that the module configuration can be
optimized.
The vibration channel must be configured for a positive, constant current
supply and the transducer power output that is connected to the spare signal
connection. (Link terminals 1 and 2 in channel 0/2, see the example in the
preceding graphic.) Depending on the transducer that is used, the sensor can
power both the vibration and the temperature sensing circuitry from one
constant current supply. For sensor types that require a separate power supply
for each, repeat power linking and configuration for the temperature channel
as well.
IMPORTANT The wire colors that are used to connect the pins for 3-wire cables are not
always consistent between cable that is supplied by different manufacturers,
or across different series of sensors and accessories (See Table 10
).
