Introduction

The I-7080 offers 2 high speed counter or frequency input channels and 2 digital output channels. Two types of digital input are provided, one for isolated input, and the other is for non-isolated input. The isolated input provides 3750 Vrms isolation voltage and the non-isolated input provides programmable threshold voltage level. The built-in digital filter is valid for both non-isolated and isolated input and can filter out noise where the high/low pulse width is smaller than the minimum high/low width of the digital filter. The maximum count is up to 32-bit and the maximum frequency is up to 100 kHz. The module also provides programmable alarm output with non-isolated open collectors. The M-7080 supports both the Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7080. The functions of the I-7080B are the same as that of the I-7080, except that the I-7080B provides a virtual battery backup function in counter mode.
