BAH4000 - Analogausgangskarte 4xAA - 4x0-10V, Not.-Handebene
Expansion module BAH 4000 for realising manual override of analogue outputs of controllers or DDC systems (real manual operating level). Typically used with valves, air flaps and variable frequency drives in HVAC systems. Each of the 0..10 V signals can be manually overridden using the switch (Auto-0V-10V-Poti) and potentiometer for adjusting the output voltage continously. The output voltage will be represented for visual monitoring purposes by the brightness of a LED. Every output is capable to drive a current of 10 mA. Furthermore, the module BAH 4000 provides a fixed-voltage output 10 V / 10 mA. When operating in automatic mode, the desired value of the output voltage will be sent to the BAH 4000 via the network variable nvi (SNVT_str_int), where the Bytes 2..5 belong to the analogue outputs 1 .. 4. Valid values are 0 .. 255 (correlating a range of 0 .. 100%). The actual values of output voltages as well as switches' position (Auto or 0V/10V/Poti) will be passed to the LON node via the network variable nvo (SNVT_str_int). Power supply (24 V DC) has to be connected to the BAH 4000 module via the spring-type terminals (41, 42) (see wiring interface). Regarding the configuration (adressing, maximum amount of expansion modules connected to a BZK, mounting, bus connection etc.), see chapter 'Configuration'. Module is also for use with BZK1000MOD (Modbus RTU). Important technichal data: Power Supply: +24 V DC via spring-type terminals
