External Signal Interface
4-20mA analog signal to S-Link
ESI-1 is an External Signal Interface to the S-link bus. It has two analog inputs (4-20mA) that controls bow and stern thrusters proportionally.
It can operate all SEP, SHP and SAC thrusters combined with retract controller SR150000 and automatic main switch (AMS).
The ESI-1 is typically used with autopilots with 4-20mA outputs and 3rd party control systems.
