Figure 33 Loop Terminal Connections - Class B
Notes: Terminal blocks are “depluggable” for ease of wiring.
All power limited circuits must use type FPL, FPLR, or FPLP power limited cable.
Loop wiring: maximum loop resistance is 40 ohms total. These lines are fully
supervised.
Observe in and out polarity when using module and base isolators.
