Selection of the nominal value is through jumper settings that are available internally to the
TX-AFE and HIA-AFE boards. The appropriate FSD of any channel is configured at the
factory as per the customer order.
TX-AFE and HIA-AFE support a maximum overload of 1000 V continuous; 3.6 times of
nominal voltage (maximum input voltage) for 10 seconds.
Note
Wire gauge to be used for TX-AFE and HIA-AFE analog inputs: 12-22 AWG.
All analog channels are calibrated at the factory and there is no need for site
calibration.
When there is a combination of current and voltage channels, the user must
always ensure that the selected input channel is a current channel before
connecting a CT circuit.
Fast Transient Recording (optional)
The fast transient recording card is optional and need to fit in the factory.
•
The signals taken from the HIA-AFE channel are processed in order to detect a trigger
condition (when the transients occur), and to allow the digital recording of the
waveforms before and after the trigger.
•
The transient voltage (up to 6 kV) is detected by the TR module with a bandwidth of
2.5 kHz to 5 MHz.
•
Sampling rates (user configurable):
20
MHz
10
MHz
5
MHz
2.5
MHz
1.25
MHz
•
TR analog channels have a 12-bit resolution.
3.12. Digital Inputs
The INFORMA PMD-A 3U device supports 32 digital inputs and the INFORMA PMD-A 6U
device supports 32/64/96/128 digital inputs. All the input channels are bi-directional.
INFORMA PMD-A supports two voltage levels configured at the factory as per the customer
order as shown below.
•
For nominal voltage 24 V to a maximum input of 250 V:
o
Less than 12 V – No activation
