The OM-USB-TEMP, OM-USB-TEMP-AI and OM-USB-5203 are USB 2.0 full speed temperature input data acquisition modules (fully compatible with both USB 1.1 and USB 2.0 ports). These are plug-and-play modules which draw power from the USB cable–no external power supply is required (except for
OM-USB-5203 which requires an ac adaptor). All configurable options are software programmable, and the modules are fully software calibrated. The OM-USB-TEMP and OM-USB-5203 provide eight differential temperature input channels. The OM-USB-TEMP-AI provides eight analog input channels that are configured as four differential temperature inputs and four differential or single-ended voltage inputs. Temperature inputs are software programmable for different sensor types including type J, K, T, E, R, S, B, N thermocouples, 2, 3 or 4-wire Pt100 RTDs, 2, 3 or 4-wire thermistors and semi-conductor sensors and are configured in blocks of two channels. A different type of sensor (thermocouple, RTD, thermistor, semiconductor) can be connected to each block of two channels (both channels must be the same type).
