تفاصيل المنتج
وصف
The 2MLF-AC8A is an 8-channel analog current input module designed by Honeywell for programmable logic controller applications. It converts analog current signals into digital values with high accuracy and fast sampling rates, interfacing through an 18-point terminal block.
Signal Processing and Isolation
The module processes 8 current input channels with a maximum conversion speed of 250 us per channel. Optical photocoupler isolation is provided between the input terminals and the internal PLC power circuit to protect control logic from field voltage spikes, though individual channels share a common ground reference without inter-channel isolation.
Addressing and Current Consumption
System integration supports flexible memory allocation, allowing either a fixed assignment of 64 I/O points or a variable assignment of 16 I/O points depending on backplane configuration. The module operates on internal logic power, drawing 420 mA from the 5 VDC backplane bus.
