AIL12 - Monitoring Of Presence / Drop-out Of 3 Phase Voltages In The Low Voltage Network

• CLIENT: IFT InForm Technologies

The product consists of two parts. AIL12-MASTER in connection with AIL12-EI is a device designed to monitor the presence / drop-out of three phase voltages in the low voltage network. AIL12-MASTER is a concentrator designed to monitor, collect and record data from the AIL12-SLAVE measurement units through the RS-485 interface.

AIL12-SLAVE

Basic properties of output interface:

• Communication with AIL12-MASTER through RS-485 according to proprietary protocol

• Communication speed of RS-485 9600 Bd

• Phoenix QC 1/4-ST-BUS type connector

• Possibility to configure the address by a mechanical switch in the 1 to 16 range

Basic properties of input interface:

• Monitoring of presence or drop-out of three mains voltages

• Voltage presence LED signalization for every input - S1 to S3

• Measurement inputs in connection with AIL12-EI conform with STN EN 61010-1: max. 600 V, CATIII

• 1 s measurement interval

• Detection of input voltage presence > 70 V rms

• Connection of inputs through external AIL12-EI impedance to screw clamps with maximal section of connected wires 2,5 mm²
