Each circuit on an 4 Input/2 Output Analog Block can accept or
provide signals in one of five analog ranges:
0-10 volts DC
-10 volts DC to +10 volts DC
-5 volts DC to +5 volts DC
0-5 volts DC
4-20 mA/1-5 volts DC
This flexibility allows these blocks to be used with a wide variety of
analog input and output devices. The block’s internal power supply
drives current mode output loads up to 300 Ohms each. For loads
up to 2K Ohms, an external 24 or 48 VDC power supply can be
used.
Configurable block features include:
Independent scaling for each input and output.
Fault reports to the host can be enabled or disabled for each
input and output.
Selectable Input Filter Time up to 1024ms.
Each input can operate in normal analog input mode, or report
only its alarm status.
Low and high alarm limits for each input, in either normal input
mode or alarm input mode.
Powerup default values for each output.
Each output can be configured to hold last state or default if
CPU communications are lost.
Input Low Alarm and High Alarm detection.
Open Wire detection on current mode inputs.
Input Underrange or Overrange.
Output Underrange or Overrange.
