If you need two analogue inputs in series, you can use an analogue input on another hardware module in series with an analogue
input on GAM3.1 (since the hardware modules are galvanically isolated from each other).
Current input
The current input may be either active or passive, and a combination of active and passive inputs may be used.
More information
See the Installation instructions for more information about the current input wiring.
Voltage input
More information
See the Installation instructions for more information about the voltage input wiring.

13.11 Governor and AVR module GAM3.2
13.11.1 Governor and AVR module GAM3.2
This governor and AVR module has its own power supply, two analogue outputs and a pulse width modulation output, five digital
inputs, a status relay output, and four relay outputs. Apart from the status relay, all these I/Os are configurable.
GAM3.2 has its own microprocessor. If the rack power supply fails, GAM3.2 can continue to be used for manual operation if it has its
own, independent power supply. The power supply terminals include circuit protection against load dump transients and JEM177
surge transients (rugged design). These terminals also include battery voltage measurement.
