IFM DL0201 is an evaluation unit designed for level monitoring and control applications. It can be used for overflow prevention, running-dry protection and leakage monitoring. The unit receives signals from connected sensors and controls its output according to configured timing conditions. IFM documentation describes it as a timer-based evaluation unit with adjustable time ranges. It supports industrial tank and liquid-level control applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The DL0201 can receive a signal from a level sensor and operate its output for a defined period. Two scaled potentiometers allow adjustment of timing functions. The timing range can be set from 0–60 seconds or 0–60 minutes according to the application. Adjustable switch-on and switch-off delays help suppress short-term level fluctuations. This makes the device useful where waves or unstable liquid levels could cause unwanted switching.
The evaluation unit can control valves, pumps or other actuators based on sensor signals. An enable function allows manual bridging of the control process. Leakage sensors can also be incorporated into suitable control arrangements. The relay and transistor outputs provide flexibility for control-system integration. This allows the unit to be used for practical liquid-level automation.
The DL0201 is suitable for tanks, reservoirs and process vessels. It can help prevent overflow by controlling a filling valve. It can also support pump protection and liquid-level supervision. The adjustable delay functions help improve control stability. The unit is suitable for industrial automation and process-control applications.
