C3G-ADM 2 ANALOG OUT-8 DC INP - 8 DC OUT
VME Input/Output module compatible with slave type interface. It comprises 2 analogue output channels, 8 24 VDC digital input chan-
nels and 8 24 VDC digital output channels with signalling by LEDs on the front panel when the channels are active. It may be added on
the Control Unit rack starting from the first free slot on the right of the basic configuration modules.
POWER FAILURE ON OPTOISOLATED ANALOGUE OUTPUTS POWER SUPPLY VOLTAGE
On the ADM module, detection of the presence of the power supply voltage (24 Vdc) of the optoisolated analogue section is provided.
Suitably positioning a 3-position jumper block it is possible to choose one of the following indications:
·
position NF/8 (Signalling level: NONE)
-
The lack of external voltage is not detected.
·
position F/8 (Signalling level: SYSTEM)
-
The lack of external voltage causes activation (1) of the FAIL bit in the status register on the VME Bus and consequently a fatal
alarm that blocks the system.
·
position NF/ST (Signalling level: USER)
-
In this case input no. 8 is dedicated to signalling the power failure at user level and therefore subtracted from normal use; any
external use of channel 8 (connection on connector J3) is ignored. The system user can programme the effect of this alarm via
PDL2.
