EM4 – sadalītas paplašinājuma vienības (EN)
EM4 – Distributed Expansion Units
The modules of the EM4 series allow the controllers of the PS4 and PS416 ranges to be simply expanded via a fieldbus system. All the modules have a Suconet K interface as standard, and bus couplers for PROFIBUS-DP are available.
Each EM4 module is equipped with switchable bus terminating resistors. This saves time and money.
