4-20 mA HART Loop Protocol
The AAM10 supports 4-20 mA HART loop protocol, enabling deterministic current signal acquisition. Input signals are insulated between systems with 1500 V AC/min withstand voltage. Transmitter power supply capability (25.0 to 25.5 V DC, ≤60 mA) allows direct powering of field transmitters, simplifying loop wiring.
Frequently Asked Questions (FAQ)
Q: Can the AAM10 provide power to connected transmitters? A: Yes, the module supplies 25.0 to 25.5 V DC with a current limit of 60 mA DC.
Q: How does ambient temperature variation affect measurement accuracy? A: A 10 deg C change results in ±8 mV drift for voltage input and ±32 µA drift for current input.
Q: Are input ranges configurable? A: Yes, input signal type and ranges are set via software configuration.
Field Installation Guidelines
Install the module securely into the I/O Module Nest.
Connect wiring to terminal blocks using M4 screws with proper torque.
Maintain shield grounding at a single point to prevent ground loops.
Separate signal wiring from high‑voltage cabling to minimize interference.
Configure input signal ranges via software before commissioning.
