Intrinsically safe for mining (Group I, protection level Ma). Hover or click on each part of the marking to see what it means.
¿Para qué entornos está certificado el Monitran MTN/M2287?
For Group I (mining), with Ex ia I Ma marking, ambient temperature from −55 °C to +115 °C and BAS02ATEX0245X and IECEx BAS 08.0013X certificates.
Do you need an intrinsically safe barrier?
Yes. It connects to the PLC or control system via a barrier. The datasheet mentions the MTL7787+ (BAS01ATEX7217) and the P&FZ787 (BAS01ATEX7005), or any other barrier conforming to note 4 of drawing ATX038. Entity parameters: Ui = 28 V, Ii = 93 mA, Pi = 0.65 W.
Is it suitable for surface industry (Group II)?
No. La hoja técnica certifica el M2287 solo para el Grupo I (Ex ia I Ma) y no indica certificación de Grupo II.
