Intrinsically safe interfaces PR 1625/60 - PR 1626/60 - PR 1626/61 Sartorius Minebea Intec

Benefits

For use in hazardous areas Suitable for Vessel, silo, Tank, Hopper scales...

PR 1625/60

A compact interface for the intrinsically safe transmission of data and signals, power supply for the EX display PR 5110 incl.

ATEX approval

PR 1626/6x

Intrinsically safe load cell supply for increased accuracy and thus verifiable* up to 3,000 e

IECEx and ATEX approvals

The interface PR 1626/6x enables a connection of load cells in hazardous areas and weighing equipment in thesafe area including W&M application. Due to the calibration approval*, this includes high-precision applications such as truck scales.

The intrinsically safe load cell supply can be selected between 7.5 V or 12 V to limit the current depending onthe resistance as required in the hazardous area.

The instruments PR 1626 and PR 1625 may be supplied with 24 VDC and have to be connected with potential equalization in the safe area.

The interface PR 1625/60 enables a bidirectional data transfer from weighing instruments out of the safe area to electronic equipment within the hazardous area. Additionally, with the remote displays PR 5110/60 or PR5110/70, another two digital signals, e.g. switch in the Ex area, can be transmitted to the safe area. For the serial link into the Ex-area current loop (TTY) is used. In the safe area an optional serial link can be selected between RS232, RS422/485 or current loop. The intrinsically safe part consists of a serial interface, two digital inputs and a power source. This power source can be used to supply the remote display PR 5110, the serial interface and theinputs in the Ex area.

Load cell interface PR 1626/60 & PR 1626/61

Intrinsically safe interface for connection of load cells in hazardous areas

Approved for applications which require verification* (OIML R 76, class III), 3,000 e PR 1626/60 has a load cell supply of 12 V

PR 1626/61 has a load cell supply of 7.5 V

Data interface PR 1625/60

Intrinsically safe interface for connection of remote displays (PR 5110/60 & PR 5110/70) in hazardous areas.

Can choose between 3 different interfaces RS 232, RS 485/422, TTY.

Bidirectional interface to the Ex-area

Digital inputs from the Ex-area

Power supply (12V) for the remote displays PR 5110 in the Ex-area
