Datasheet - IL9151

COO (Country of Origin):: DE

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
