IL9151.12 2- 50kOHM DC24V 0.2-20S, Dold Level Monitoring Relay, DIN Rail, Реле контроля

IL9151 - level relay with two separately operating changeovers

The IL9151 is used for

Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum fill level, protection against overfilling and dry running
Monitoring and control of the mix ratio for conductive liquids
General resistance monitoring tasks, e.g. recording temperature limits with PTC
Contact protection relay with delay

Features

In accordance with IEC 255, VDE 0435 Section 303
3 electrode connections for 2-point or 1-point level control
The measuring circuit galvanically isolated from the mains is immune from high levels of interference
Max. lead length to the electrodes: 1500 m
Wide setting range of 4 → 450 kΩ, which enables differentiation between liquid and foam
Response and fallback delay: 0.2 → 20 s adjustable separately for MIN and MAX level
Programmable for: 2 separately controlled output relays for MIN and MAX level or jointly controlled output relays in 2-point hysteresis level control
Programmable for: Operating or rest current principle
Measuring circuit for electrodes works on AC voltage generated internally in the device (approx. 30 Hz); therefore no electrolysis occurrence in the fluid
LEDs to indicate operational readiness and contact position
2 output relays each with 1 changeover
35 mm overall width

Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use.

Application Examples

Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the:

Monitoring and control of liquid levels
Protection of pumps against dry running
Ability to detect liquid leaks in a system
Control of media mixing ratios
Control of liquid levels
