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.

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)
Devices available in 2 enclosure versions:IL 9151: Depth 59 mm, with terminals at the bottom for installation systems and industrial distribution systems according to DIN 43880SL 9151: Depth 98 mm, with terminals at the top for cabinets with mounting plate and cable duct
Width: 35 mm
