InterBus 
Interface Module 
(NOA) 
The Quantum InterBus is the interface module to the InterBus bus. The InterBus bus 
is a fieldbus network designed for I/O blocks and intelligent devices used in 
manufacturing. It offers a master/slave topology that permits deterministic I/O 
servicing over it’s 13 km twisted pair network.
LonWorks 
Modules (NOL)
Quantum NOL modules provide connectivity between a Quantum controller and a 
LonWorks network, based on Echelon’s LonWorks technology. The NOL module is 
offered in three models for different transceiver types, and supports three twisted-
pair media types with different network topologies or data transfer speeds.
Profibus 
Interface Module 
(CRP)
Quantum Profibus module is the interface module to Profibus-DP networks. The 
interface modules use Type A, shielded twisted pair to join inline connectors, with or 
without service ports and bus terminators.
AS-i Interface 
Module
Quantum AS-i modules provide connectivity between a Quantum controller and AS-
i networks. AS-i bus cable is an unshielded flat two-wire link on which 
communication and power are transmitted to connected devices. The media 
insulation is self-healing to accommodate junction block removal.
