AI: DC analog input, usually 0-5V or 4-20MA standard signal input
DI: Switch value input reflects whether the status of the switch value is open or closed.
AO: DC analog output is generally 0-10V or 4-20MA and other signal outputs, used as signal conditioning
DO: Switching output can be a relay or high-power tube, etc.
PI: Pulse input accumulates pulses
PO: pulse output AI/AO – analog input/output,
DI/DO – switch input/output switch: divided by voltage level, there are 220VAC, 110VAC, 24VDC, divided by isolation method, there are relay isolation and transistor isolation.
Analog quantity: According to the signal type, there are current type (4-20mA, 0-20mA), voltage type (0-10V, 0-5V, -10-10V), etc. According to the accuracy, there are 12bit, 14bit, 16bit, etc. .
