Configured state
You can configure the normal transistor state in software in the display unit or PICUS. Under Configure > Input/output, select the
terminals, then select Normally de-energised (the default) or Normally energised for the Coil state.

1. Function: The digital output function assigned to the terminals. The
controller software activates the function. For example: Breakers > [Breaker]
> Command > [*B] Close.
2. Transistor: The controller closes the transistor when the function is
activated.

13.8.4 Digital input characteristics
IOM3.4 has two groups of digital inputs. The first group is terminals 15 to 22, with a common on terminal 23. The second group is
terminals 24 to 31, with a common on terminal 32. The groups are not connected to each other.

13.9 Engine interface module EIM3.1
13.9.1 Engine interface module EIM3.1
The engine interface module has its own power supply and a tacho input to measure speed. It also has four relay outputs, four
digital inputs, and three analogue inputs. These I/Os are configurable.
The power supply terminals include circuit protection against load dump transients and JEM177 surge transients (rugged design).
