Level Sensing Relay
SL 9151

The IL 9151 and SL 9151 level sensing relay of the VARIMETER series have 3 electrode connections that can be used for 2-point and 1-point level control. The response value can be set using a rotary switch, as can the response and release delay. The devices can be programmed for the open and closed-circuit operation.

Advantages
. 3 probe connections for 2-point and 1-point level control
. Large setting range: 2 ... 450 kΩ

Features
. According to IEC/EN 60255-1
. Separately adjustable response and release time delay for MIN- and MAX-level
. Programmable for:
- 2 separate controllable output relays for MIN and MAX level
- Common controlled output relays for 2-point hysteresis level control
- Open circuit operation (output relay activated in case of error)
- Closed circuit operation (output relay not activated in case of error)
. For auxiliary voltages of AC 24 ... 400 V or DC 24 V
. LEDs for operation and state of contact
. 2 changeover relays with 1 changeover contact each
. With safe separation according to IEC/EN 61140, IEC/EN 60947-1 (AC 24 ... 240 V)
