5.2.4 Milliampere output control
The milliamp current loop is the prevailing process control signal in many industries. It is an ideal
method of transferring process information because a current does not change as it travels from a
transmitter to a receiver. It is also much more simple and cost-effective.
The benefits of 4...20 mA loops:
• 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

mA outputs. The outputs are activated in groups of two: channels 1 and 2 are
activated together, as are channels 3 and 4 (see the image below).
