7.4.1 TROXNETCOM B24A, B24AM, B24AS
A controller (master) communicates with the control modules (slaves, up to 31 per master)
Free bus topology of the two-wire cable for data and energy
Simple and intelligent wiring system
Fig. 33: Wiring example for attachments B24A and B24AS
BN Brown (+)
BU Blue (–)
The actuator and the AS-i control module are factory wired.
An AS-i bus (+/–) is used for both voltage supply and signals.
The connecting cables of the AS-EM/SIL module are fitted with wire end ferrules.
