OMEGA Engineering, Inc. Universal Current/Voltage Input Card OMB-DBK15

Each OMB-DBK15 multiplexing input card provides sixteen channels of current or voltage input to OMEGA’s OMB-LOGBOOK and OMB-DAQBOARD-2000 Series data acquisition systems. An OMB-LOGBOOK and OMB-DAQBOARD-2000 Series can accept up to 16 OMB-DBK15 cards, for a total of 256 potential analog input channels per system. The OMB-DBK15 features a 16-channel multiplexer and a programmable gain input amplifier. Its durable component sockets accept resistors that configure each channel for either current-to-voltage conversion or for voltage attenuation. The OMB-DBK15 is supplied with sixteen precision 250 ohm resistors for making 4 to 20 mA measurements, and sixteen sets of 6:1 voltage dividers for accommodating up to ±30 V* inputs. (* ±10 V to 30 V input signals can be measured by installing attenuation resistors on the card) The OMB-DBK15 can also accept other, user-supplied resistor values, facilitating user-selectable current-to- voltage conversion or voltage attenuation factors. When employed without resistors, the OMB-DBK15 provides sixteen differential voltage inputs, which accommodate ±5 V full scale inputs. The OMB-DBK15’s input amplifier is software programmable for x1 or x2 gain per channel, and for unipolar 0 to +10 V or bipolar -5 to +5 V input per channel.
