Module status
The status of the module can be monitored in three ways.
1.
GYDA System Controller (optional).
2.
GPI at the rear of the sub-rack.
3.
LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself, whereas the GYDA
System Controller is a separate module giving detailed information on the card status. The
functions of the GPI and the LED’s are described in sections 5.1 and 5.2. The GYDA
controller is described in a separate user manual.
5.1
GPI Alarm – Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector outputs, sinking to ground when an alarm is triggered. The GPI
connector is shown in Figure 7.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V
