ISO-LDH

The ISO-LD series is a bus-type isolated loadcell input board. The isolation inputs can operate with up to 500 Vrms of common-mode voltage. The ISO-LD series features a 12-bit analog-to-digital converter, on board 1 KB FIFO buffer , one loadcell signal input channel, one analog input channel, 8-channel 12 ~ 24 V isolated digital inputs, 7-channel isolated open-collector digital outputs, one programmable 8-bit LED indicator to indicate the magnitude of strain gauge input signal. The ISO-LD series board is suitable for static force measurement and dynamic force analysis. Because there are on board excitation voltage, high gain amplifier, you don*t have to buy any excitation voltage and signal conditioning module. In other words, it save your money and space. The board also have some special features, such as 1.12-bit programmable offset voltage. Therefore the user can cancel the DC bias and amplify the AC signal 2.The isolated structure eliminate the ground loop noise and protect your computer. 3.On board FIFO buffer support gap-free A/D conversion under DOS and Windows environment. 4.Except the loadcell input channel, there are a lot digital I/O and one analog input channel .The user can implement a measurement and analysis system.
