Pico USB TC-08 Single Channel Terminal Board PR121. This Pico single-channel terminal board plugs into a channel on the Pico TC-08 data logger ( < 492-5105') 492-5105/ ) and turns it into a 20-bit high resolution data logger. Screw terminals enable wires to be attached to the data logger without soldering. The four input ranges (±50mV, ±500 mV, ±5 V and 4–20 mA) allow a wide range of other sensors and signals to be measured.
