The M-7003 is a 16-bit, 8-channel analog inputs and 4-channel for relay output. All of its channels are Form A type relay module that provides programmable input range on all analog channels (±150 mV, ±500 mV, ±1 V, ±5 V, ±10 V, ±20 mA, 0 ~ 20 mA and 4 ~ 20 mA). Each analog channel is allowed to configure an individual range and has 120 VDC high overvoltage protection. Jumper selectable for voltage or current input. The sampling rate of M-7003 is changeable; there are fast mode and normal mode for your consideration. M-7003 also has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.
