IC200ALG240
Analog Input Module, 16 Bit Voltage/Current, 1500VAC Isolation, 8 Channels
Analog input module IC200ALG240 provides eight analog inputs. Features include:
Eight isolated 4-20mA current input channels
Sixteen-bit converter resolution
Open wire detection
High-accuracy factory calibration
The following additional features are software-configurable:
Per-channel selection of 4-20mA current or +/–10V voltage inputs
Selectable input filter to reject normal mode AC pickup noise
Selection of default/hold last state operation
Per-channel selection of default values
Per-channel selection of under-range and over-range diagnostics levels
Per-channel selection of alarm levels
Per-channel scaling
Field re-calibration on command from VersaMax PLC CPU

In current mode, a separate power supply may be required for isolated inputs.
The module provides 8 words of analog input data to the system CPU or NIU.
LED Indicators
The green FLD PWR LED indicates the presence of both backplane power and field
power for the analog field-side circuits. The absence of either backplane or field power
turns off the FLD PWR LED.
The OK LED indicates module status:
On green indicates normal operation
Flashing green indicates boot mode or update
Flashing amber indicates self-diagnostic error
Off indicates no 3.3V backplane power
