Analog Loop Wiring
Figure 31: 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 power limited and fully
supervised.
• Observe in and out polarity when using module and base isolators.
