Analog Input Module, 15 Bit Voltage 15 Channels
Analog input module IC200ALG263 / IC200ALG265 provides an interface to 15
voltage inputs. The inputs are single-ended, with all inputs sharing a common
return. Module IC200ALG265 is rated for use in SIL2 applications.

IC200ALG263
ANALOG INPUT 15BIT
VOLTAGE 15CH
OK
The module receives power from the backplane power supply. No external
power source is required for module operation. Power for the user’s
transceivers must be supplied from an external source.
Intelligent processing for this module is performed by the CPU or NIU. The
module provides 15 words of analog input data.
LED Indicators
The green OK LED is ON when backplane power is present, internally
generated field power is functioning properly, the module has been configured,
the module has been recognized on the backplane, and all diagnostic tests are
executing as expected.
Diagnostics
The module reports a Loss of Internal Power fault for field-side circuits.
The module reports an Internal Hardware fault upon detection of an A/D
conversion malfunction. The module detects this malfunction by applying a known
stimulus to the A/D conversion path and verifying the expected result. If an
unexpected result occurs three times consecutively, the module stops scanning,
turns off the OK LED, and reports an Internal Hardware fault. The module must
be power cycled or replaced to clear this fault.
Configuration Parameters
The analog inputs are software-configurable to either default or hold last state
upon loss of module.
