Choose analog, thermocouple, and/or RTD I/O modules when you need:

The ArmorPoint analog and temperature I/O modules support: on-board, channel-level data

alarming (four set-points per channel); scaling to engineering units; channel-level

diagnostics (electronic bits and LEDs); and integer format.

y Individually configurable channels to use the module(s) with a variety of sensors.

y On-board scaling to eliminate the need to scale the data in the controller. Controller

processing time and power are preserved for more important tasks, such as I/O control,

communications, or other user-driven functions.

y On-line configuration. Modules can be configured in the RUN mode using the

programming software or the control program. This allows you to change configuration

while the system is operating. For example, the input filter for a particular channel could

be changed, or a channel could be disabled based on a batch condition.

To use this

feature, the controller and network interface must also support this feature.

y Over- and under-range detections and indications. This eliminates the need to test

values in the control program, saving valuable processing power of the controller. In

addition, since alarms are handled by the module, the response is faster and only a

single bit per channel is monitored to determine if an error condition has occurred.

y Ability to direct output device operation during an abnormal condition. Each

channel of the output module can be individually configured to hold its last value or

assume a user-defined value on a fault condition. This feature allows you to set the

condition of your analog devices, and therefore your control process, which may help to

ensure a reliable shutdown.

y Ability to individually enable and disable channels. Disabling unused channels

improves module performance.

y Selectable input filters This lets you select the filter frequencies for each channel

that best meets the performance needs of your application based on environmental

limitations. Lower filter settings provide greater noise rejection and resolution. Higher

filter settings provide faster performance.

Note: The analog modules provide four input

filter selections; RTD and thermocouple modules provide six.

y Selectable response to broken input sensor. This feature provides feedback to the

controller that a field device is not connected or operating properly. This lets you specify

corrective action based on the bit or channel condition.

y High accuracy. The modules share a high accuracy rating of ±0.1% of full-scale

accuracy at 25 °C.
