Description:
Yokogawa Analog I/O modules function as signal converters; byinputting field analog signals into these modulesYokogawaAnalog I/O Module AAI841-S50
STANDARD SPECIFICATIONSof AAI841-S50
Current/Voltage Input Modules(Non-Isolated)
These modules provide 16 inputs of mainly 4 to 20 mA DC or 1to 5 V DC standardized signals from 2-wire/4-wire transmitters.
They can be used in dual-redundantconfiguration.
