GE IC200ALG240 Analog Input Module
In current mode, a separate power supply may be required for isolated
inputs. Module 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
Host Interface
The module provides 8 words of analog input data
Diagnostics
The module reports over/under range, open wire, loss of field power
supply, non-volatile memory storage fault, and high/low alarm
diagnostics.
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

Preinstallation Check
Carefully inspect all shipping containers for damage. If any equipment is
damaged, notify the delivery service immediately. Save the damaged
shipping container for inspection by the delivery service. After unpacking the
equipment, record all serial numbers. Save the shipping containers and
packing material in case it is necessary to transport or ship any part of the
system.
