Installation and Wiring
Modules Which Can be Used
In case of the DA100 Stand-alone type
Input module, alarm output module, DI/DO module, extender module, communication interface
module, and retransmission module.
Number of modules that can be connected: 6 (of which at least one must be a communication
interface module)
DI/DO module: not more than one
Input module: max. four (up to 40 channels)
Input module + alarm output module + DI/DO module + retransmission module: max. five
In case of the DA100 Expandable type
Not more than one DI/DO module can be connected to all units.
• Main unit
Alarm output module, DI/DO module, and communication interface module.
(Note: The input module and retransmission module cannot be connected.)
Number of modules that can be connected: 4 (of which at least one must be a communication
interface module)
DI/DO module: not more than one
Alarm output module + DI/DO module: max. three
• Subunit DS400/DS600
Input module, alarm output module, DI/DO module, extender module, and retransmission
module.
Number of modules that can be connected: 4 for DS400, 6 for DS600 (up to 300)
DS400: Input module + alarm output module + DI/DO module + retransmission module: max.
four
DS600: Input module + alarm output module + DI/DO module + retransmission module: max.
six
Note
• No alarm output module or DI/DO module can be connected to the right side of an input module, since
the rise in temperature would hinder the measurement accuracy.
• When mounting universal and power modules, or DCV/TC/DI and power modules together, keep the two
modules apart at a distance equal to the width of at least two slots. Failure to observe this precaution
may result in the measuring accuracy falling outside the guaranteed range.
• No retransmission module can be connected to the right side of universal input module, DCV/TC/DI
module, since the rise in temperature would hinder the measurement accuracy.
• Verify the type of module by the seal on the top side.
