OVERVIEW
The Time Stamp is one out of a series of four modules. The differentiation
between the four different modules is shown in the table below.
*
140 ACI 050 00sc
current only
* 140 AVI 050 00sc
voltage only
* 140 ACI 051 00sc
current or voltage combination
140 ACI 052 00sc
current or voltage combination
with time and date stamping
* These modules are covered in a separate manual (Publication #0300169).
Each module will accept 32 single ended analog inputs. The inputs will be
divided into four groups of eight inputs each. Each group will have 15V
isolation to the other groups. Analog inputs within a group will have 0V of
isolation channel-to-channel. All inputs will have 500V ac isolation channel-
to-backplane.
The module has been designed for projects that include large quantities of
analog inputs. Process control and data acquisition applications for industries
such as utilities, waste water, oil and gas, food and beverage, and building
automation are ideally suited for this module. The time and date stamp feature
is perfect for remote terminal unit (RTU) applications or for supervisory control
and data acquisition (SCADA) applications requiring programmable alarm
levels.
Input channels include over voltage circuit protection, over and under range
detection and active notch filtering. The voltage mode of the module handles
four different voltage ranges and the current mode handles two current ranges.
You can configure the module to provide data in one of four data formats. Set
up of the module is very simple through the use of configuration and status
registers using Concept, Modsoft or Taylor programming software.
