TEDS Transducer ID Module
About the TEDS Transducer ID Module
The TEDS Transducer ID module (TEDS module) includes a chip that can
store TEDs IDs used to identify the transducer, and optional shunt-
calibration resistors. The controller communicates with the TEDS module
through a IEEE 1451.4, Class 2 smart transducer interface.
Transducer connections
TEDS Module options include different connectors that allow the TEDS
module to connect directly to the transducer. The TEDS Transducer ID
module connects to a DUC mezzanine card through a 572414-xx cable. This
cable has an RJ-50 connector that connects to the Model 494.40 I/O Carrier
card and a JT connector that connects to the TEDS module.
Integrated shunt-
calibration resistors
You can order the TEDS module with integrated shunt-calibration resistors.
To use a TEDS module with integrated shunt-calibration resistors, you must
insert a jumper plug (MTS part number 100-188-097) into that transducer’s
shunt calibration socket (located on the front of the I/O carrier board).
External shunt-
calibration resistors
To use an external shunt-calibration resistor with a transducer, you can order
a TEDS module with internal shorting jumpers. You must mount the external
shunt-calibration resistor on a plug assembly (MTS part number 114-338-
26) and plug that assembly into that transducer’s shunt calibration socket
(located on the front of the I/O carrier board).
