Q.seriesGantner Instruments Test & Measurement GmbH 494 Connection → Q.brixx A109: Connecting I/O and outputs4.12 Q.brixx A109: Connecting I/O and outputsThe Q.brixx Module A109 has four electrically isolated analogoutputs, four digital inputs and four digital outputs. The assign-ment of both connector strips is not identical. The plug number isspecified in the following. The connection terminals have num-bers for identifying the connections. If several connections arepossible, you will find the associated ones in each case at thesame place in the circuit diagrams, for example each of the fig-ures quoted in the second place belong to one possible connec-tion method.The designations 0 V and +V refer to the (external) supply volt-age connections, NC indicates “not assigned”. Analog ground (–)and the (external) supply voltage (0 V) are electrically isolated inthe module.Fig. 4-51 Pin assignment for Q.brixx Module A109.4.12.1 Digital input and output, Plug 1On Plug 1 contacts for four inputs and four outputs are available.Since the inputs and outputs of this module are electrically iso-lated from the supply voltage, you must also connect 0V for theinputs and 0 V and a supply voltage (+V) for the outputs.DinDoutInput Output6, 7, 8, 9+V10 (0V)110 (0V)2, 3, 4, 5+VU3, 5, 7, 9 (+)4, 6, 8, 10 (-)I3, 5, 7, 9 (+)4, 6, 8, 10 (-)Plug 1, digital inputs and outputsPlug 2, analog outputs1 +V2 DOut 13 D Out 24 D Out 35 D Out 46 D In 17 D In 28 D In 39 D In 410 0 V1 NC2 NC3 AOut 1+4 A Out 1–5 A Out 2+6 A Out 2–7 A Out 3+8 A Out 3–9 A Out 4+10 A Out 4–10110 1Plug 1Plug 2
