Frequently Asked Questions
Q1: What does “separately powered” mean for transmitters?
A1: It means the transmitter gets its power from another source, not from this interface.
Q2: Can I use this with both conventional and smart transmitters?
A2: Yes, it works with standard 4-20mA transmitters and HART smart transmitters.
Q3: How do I connect a hand-held communicator?
A3: Dedicated terminals (3-4, 7-8) make HHC connection simple.
Q4: What is the maximum load resistance?
A4: It can handle up to 600Ω for conventional transmitters and 250Ω±10% for smart transmitters.
Q5: Is this module intrinsically safe?
A5: Yes, it’s certified for Zone 0/Division 1 hazardous areas.
