The XV308 provides 8 channels for analog input and 8 channels for universal digital input/output. Analog Input channels are Single-ended type and provide a programmable input range (±1 V, ±2.5 V, ±5 V, ±10 V, ±20 mA, 0 ~ 20 mA, 4 ~ 20 mA). Each Analog Input channels also provides a high overvoltage protection of 120 VDC. Universal digital input/output can be selected via wire connections. Digital input channels are sourcetype and can be used as 32-bit counters. Digital output channels are sink-type with short circuit protection and options for configuring power-on digital output values.
