T24-AO1 [Analog Output]

Overview
The T24-AO1 and T24-AO1i provides an analogue output for the acquisition modules such as T24-SAx and T24-
SAFx. The T24-AO1i is housed in an IP67 housing for industrial installation whilst the T24-AO1 is designed for
desktop mounting.
The output can be selected from the following pre-calibrated Voltage and Current ranges. 0-10Volts, +/-10Volts,
0-5Volts, +/-5Volts, 0-20mA, 4-20mA both of which can be used in a 'sink' or source mode.
The T24-AO1 is configured by entering engineering values against the Output Minimum and Maximum Values. The
analogue output is updated at a rate configured by the acquisition module 'TXInterval'.
LED's and in the case of the T24-AO1i, open collector outputs, provides indication of the state of the radio link,
remote battery life and remote status.
A digital Input allows for zeroing of the incoming data value.
Configuration
The T24-AO1 is configured by setting the Data Tag of the device whose data you wish to reflect onto the analog
output.
Once you know the data tag you then need to work out which calibrated values from the acquisition module you
want represented by the selected analog output minimum and maximum levels.
For example: A T24-SA has been calibrated to give 0 to 10 tonnes output. You have selected a 4-20mA analog
output and want the output to give 4mA at 0 tonnes and 20mA at 8 tonnes. Simply set the In Minimum to 0 and In
Maximum to 8.
Next you set the desired actions when errors occur.
Communications
To configure the device you will use the Read and Write mechanisms described in the Data Packet Structures
section to read and write parameters and execute commands.
