• the dominant standard in many industries
• the simplest option to connect and configure
• uses less wiring and connections than other signals, thus greatly reducing initial setup costs
• good for travelling long distances, as current does not degrade over long connections like
voltage does
• less sensitive to background electrical noise
• detects a fault in the system incredibly easily since 4 mA is equal to 0 % output.
Milliampere (mA) outputs
AQ-200 series supports up to two (2) independent mA option cards. Each card has four (4) mA output
channels and one (1) mA input channel. If the device has an mA option card, enable mA outputs at
