Specifications and System Configuration
2.1 Electrical Specifications
Input power 24V DC
Operating voltage
90% ~ 110% of rated voltage
Power
consumption
Host Max. (maximum number of channels ) 6W + 5W × number of measurement
expansion modules in parallel + 3W × number of I/O expansion module in parallel
Expansion cassette power consumption is already included in the host or
measurement expansion module
Installation
requirement
Please install according to the sequence【Host → measurement expansion
modules (Max. 7 modules)→ I/O expansion modules (Max. 8 modules)】If the
measurement expansion modules include DTMN02-x series, be sure to install
DTMN08 / N04 before installing DTMN02-x,
Each DTM group can only expand one DTMN02-x measurement expansion
