External power supply source
Dedicated safety barrier PLUM INT-S3 with following features:
• Ex classification II (2) G [Ex ib Gb] IIA
• Power supply source for MacBAT 5 – U
IN
=5,7V
• Enabling EVC functionalities requiring external power supply: frequency mode of digital output,
1s measurement cycle, HF pulse inputs
• Safety barrier for signals from outside of the hazardous zone
o RS485 port separation – enabling the transmission from equipment installed out of the
Ex Zone
o Digital outputs separation – transmitting signals from MacBAT 5 digital outputs to
automatic systems outside the Ex Zone
• Powering of the INT-S3 interface – 10,5-30V DC
INPUTS AND OUTPUTS
