The recorder output terminals are isolated from the controller circuitry
to avoid any interference and are user-switchable between 0 to 20
mA or 4 to 20 mA.
The controller is housed in a rugged, modular, fiber-reinforced ABS
housing.
All models can be wired to work with 110/115V or 220/240V at 50/
60 Hz power supplies.
