Chapter 1 About the Dynamix 1444 Series Dynamic Measurement Module
Channel Class and Category
Dynamix 1444 Series monitors can be used with shielded or unshielded
Ethernet media. For cables longer than 3 m (9.8 ft), use shielded cable or cable
that is entirely enclosed within a shielded environment, such as an electrical
enclosure or metal conduit. This consideration helps ensure EMC compliance.
See Rockwell Automation® documents 1585-BR001B-EN-P Industrial
Ethernet Media and ENET-RM002C-EN-P Ethernet design considerations
for information on selection of the appropriate Ethernet media for your
application.
Recommended Cables
Only straight connectors are recommended for use with the 1444 products.
Verify that the temperature rating of the selected cable is appropriate to the
environment in which the 1444 product is installed, up to and including 70 °C
(158 °F).
Compatible Sensors
The following types of sensors can be connected to a DYN module:
• 2-wire piezoelectric acceleration sensor
• 3-wire piezoelectric acceleration sensor with temperature sensing
• 2-wire piezoelectric dynamic pressure sensor
• 2-wire piezoelectric velocity sensors
• 2-wire self-generating velocity sensors
• 3-wire piezoelectric acceleration sensor
• 3-wire eddy current probe (ECP) systems
• Buffered voltage outputs
• Process proportional voltage signals (such as temperature, pressure, and
flow)
A transducer supply is available for each channel. The transducer supply can be
independently enabled and configured for negative or positive operation (25
mA at 24V) or as a positive constant current source at 4 mA, 24V. The
transducer power supply output is made available at a separate terminal so that,
by appropriate wiring, it is possible to connect either two or three wire
transducers.
