The EL9210 potential feed terminal with fuse and diagnostics enables the setup of different potential groups with a fused standard voltage of 24 V DC. The supply voltage is taken up via the front terminal contacts, fused and passed through to the adjacent terminals via the internal power contacts. The fuse is a 6.3 A fuse, which can be replaced at the front.
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.
The KL9210 power feed terminal makes it possible to set up various potential groups with the standard voltage of 24 V DC. In order to monitor the supply voltage, the terminal with diagnostics reports the status of the power feed terminal to the Bus Coupler through two input bits. It is thus possible for the controller to check the distributed peripheral voltage over the fieldbus.
