Outputs
Pump Output (4 Amps @ 12vdc)
The TD-1000 has one output, which can be used to control an interposing relay for a
pump such as a waste tank discharge pump. An auto-off feature is standard and is
particularly helpful in preventing damage caused by a pump running dry. The auto-off
point is programmable.
Alarm Output (300Ma @ 12vdc)
The alarm output can be programmed to activate a relay when the waste tank reaches
the set alarm point, or can be used to disable the toilet, or used to activate a buzzer
(buzzer supplied)
