Interface converter - PSM-ME-RS232/RS232-P
2744461

Interface converter, for the isolation of RS-232 (V.24) interfaces, 4 channels, rail-mountable


Product Details


A considerably higher level of immunity to interference can be achieved in industrial applications by using V.24 (RS-232) isolator modules. The high-quality 3-way isolation results in an electrically isolated and interference-proof V.24 (RS-232) interface. This decoupling also protects the expensive terminal devices against damage.
