Process Control Signal Acquisition & HART Loop Integration
The 2MLF-AD16A module executes high-speed digital conversion across 16 analog input channels at a maximum throughput rate of 500 us per channel. Built to interface with process instrumentation networks using 4-20 mA HART loop protocol transmitters and standard voltage signals, the module relies on a photo-coupler isolation barrier rated between field wiring terminals and internal backplane logic power. Onboard calibration maintains high conversion accuracy (+/-0.2% at nominal room temperature) to ensure continuous monitoring and drift-compensated processing within industrial DCS and PLC architectures.
Frequently Asked Questions
Q: Is channel-to-channel galvanic isolation provided on the 2MLF-AD16A analog input module?
A: No, the module provides photo-coupler isolation between the field input terminals and the central PLC backplane power, but channels share a common ground reference.
Q: What are the backplane I/O addressing requirements for this 16-channel module?
A: Depending on system addressing settings within MasterLogic-200 software, the unit assigns either 64 fixed points or 16 variable points on the backplane bus.
Q: What is the backplane power supply current consumption for the 2MLF-AD16A?
A: The module draws a nominal logic supply current of 330 mA at 5 VDC directly from the rack backplane.
Field Installation Guidelines
- Ensure rack power supply is turned off before inserting or removing the 2MLF-AD16A from the base unit backplane slot.
- Terminate field signal conductors to the 32-point terminal block, ensuring correct wire pairing for all 16 analog input channels.
- Utilize individual shielded twisted-pair cabling for all analog process signals to prevent high-frequency noise pickup.
- Ground cable shields at a single central cabinet ground point to prevent ground loops across non-isolated signal commons.
