USB TC-08 Single-Channel Terminal Board Users Guide USB TC-08 Single-Channel Terminal Board Users Guide Pico Technology 1 Safety notices You MUST observe the following safety notices to prevent damage to equipment and personal injury. DO NOT do not connect the terminal board to any voltage source exceeding the maximum input range printed on the board. DO NOT connect the terminal board to a mains (line voltage) electrical supply. The high voltage will damage or destroy the equipment and may cause serious or fatal injury. 2 Overview 2.1 Introduction The USB TC-08 Single-Channel Terminal Board is an accessory for the Pico Technology USB TC-08 8-Channel Thermocouple Data Logger. The screw terminals allow wires to be attached to the data logger without soldering and enable the USB TC-08 to measure voltages from 0 to + 5 V or 4-20 mA loop currents. The terminal board is designed for use with the USB TC-08 and is not guaranteed to work with other thermocouple data loggers. 2.2 Specifications Dimensions 57 x 27 x 14 mm (approx. 2.3 x 1.1 x 0.6 in.)
