Question:
What are the AxLink maximum cable distances?
Answer:
The wiring distance specifications describe the total wiring distance between external devices and the Central Controller. For example, FIG. 1 illustrates a star wiring topology, in which the total wiring length is 1,200 feet (366 m
The wiring distances for the AXB-MPE Master Port Expander and AXB-SPE Slave Port Expander devices are calculated on a per-port basis. The ports on these devices are isolated and electrically independent with respect to each other.
The maximum cable lengths by electrical current and wire gauges (AWG). These distances are based on a min. of 13.5 volts available at the Central Controller's power supply.
Maximum AxLink current and cable lengths by wire AWG:
