Figure 3: Terminals
Wire and Cable
Terminal blocks TB1 to TB7 accept 12 AWG to 24 AWG wire. Use 16 AWG or 18 AWG wire for the power supply in long
wiring runs, which can be up to 1km (1,000 meters) long.
We recommend using BELDEN 9841 for communications. This wire has 120 ohm input impendence, which will eliminate
RS-485 communication problems.
Power Requirements
The B6M power supply voltage requirements are nominally 24VAC or 24VDC.
The B6M has full wave rectifier and half wave rectifier on board. You will damage devices if you mix half wave and full
wave rectifiers on the same AC source. Use extreme caution when sharing a common AC source. Sharing a common DC
source is less problematic.
Specifications subject to change without notice.
