BMA0004

The BMA0004 adds four analog outputs, 0(2) to 10 V DC at up to 2.5 mA each, to a DDC4000e or DDC520 controller. Each output has a rotary switch that sets manual operation from 0 to 100 % or returns it to automatic, so plant can be driven by hand during commissioning or a fault. Four status LEDs show the outputs and one shows bus traffic. It connects to the CAN bus either as a fieldbus module (up to 2000 m) or as a cabinet bus module (up to 200 m), and is addressed from 01 to 63 with two rotary switches. Push-in spring terminals and hot-plug capability allow replacement without shutting the bus down. Support terminals carry up to 230 V AC, 6 A. It offers the same four analog outputs as the FBM044 and FBM044W.
