Features
Isolated Amplifier Function is installed This product contains eight isolation amplifier channels. The board provides isolation between the input and output signals and also between channels. The input gain can be set independently for each channel to either 1 or 200. Cold Junction Compensation Circuit for Thermocouple Sensor is installed This product has a cold junction compensation (CJC) circuit used for all eight channels. The CJC circuit is available when the 200 gain is selected. The circuit allows a thermocouple to be connected directly to this product. Current Input Function is installed Each of this product channels has a 250Ω current monitor resistor. This enables a -40mA - +40mA current input to be converted to a -10V - +10V voltage input. Easy connection to external signal with M3 screw type terminal blocks This product has M3 screw-type terminals for connecting the analog input signals. The analog output signals for the analog E series boards also use M3 screw-type terminals. These terminals make it easy to connect external devices. Other Features Easy to connect with the analog E series board through a PCB37PS Series (option). This two products can be cascaded to provide a maximum of 16 isolated amplifier channels. Either PC power (via CN1) or an external power source can be used to supply power to this product. This product can be installed on the DIN rail using the optional DIN rail installation adapter (DIN-ADP1).
