TM1800 ZP-CG01E CG0757JE
4 MODULES
4.4 Analog module
Analog channel is for measurement of motion, volt-
age, current, vibration, density, pressure etc.
The module is for motion measurements with stand-
ard linear or rotary transducers (resistive analog type),
shunts and 4-20 mA transducers.
Standard XLR male contact connection in module.
Transducer cable with female XLR contact.
„ „
Three channels per module
Terminal Configuration
The terminals are grouped in three similar sections A,B
and C suited for 3-phase operation (L1 L2 L3, RST).
Standard XLR male connection in module. Cable with
female XLR contact needed, included in the delivery of
TM1800.
0 earth
IN
input value from transducer
OUT output from unit to transducer
Note
These channels should be turned off in CABA
Local or CABA Win when not in use, to avoid
error messages.
Number of modules needed
1 module for three analog measurements simultane-
ously.
Example: For 3 motion measurements, 1 voltage and
1 current measurement you need 2 modules.
For technical specification see “Analog Module” in
chapter 9 Specifications.
4.5 Digital module
Digital channels for measurement of motion, both
linear and rotary with incremental/digital transducer.
„ „
Number of channels 6x per module
„ „
Measurement ranges transducer resolution up to +/- 32000
pulses.
„ „
Power supply: 5 V +/-5% and 12 V DC +/-5% at 200 mA.
For specifications, see “Digital Module” in chapter 9
Specifications.
Terminal configuration
The terminals are grouped in three similar sections A,B
and C suited for 3-phase operation (L1 L2 L3, RST).
Interface type: RS422 female connection on module,
cable with male RS422 needed, included in the deliv-
ery of the Digital module.
IMPORTANT
Make sure that the transducer you con-
nect has the correct pin configuration.
Wrong configuration can damage the
TM1800.
Number of modules needed
1 module for each six digital motion measurements.
