Special features: compact design through the combination of inputs and outputs in one terminal no bouncing due to mechanical switches thanks to 3 ms input filter short-circuit proof outputs protected against reverse polarity with output current up to 0.5 A tool-free connection by direct plug-in technology for solid wire conductors increased packing density with 16 connection points in the housing of a 12 mm terminal block
The KL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitized with a 16 bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system.
The MP-Bus master terminal enables direct connection of MP-Bus slave devices. The MP-Bus was developed by Belimo for connecting valves, throttle valves, air valves and fire dampers for window ventilation systems.
