Yokogawa AAI141-H50 S1 16-Channel HART Analog Input Module

AAI141-H50 S1 receives 4 to 20 mA DC signals on sixteen non-isolated input channels. It is an analog input module for FIO process-signal acquisition, rather than an analog output module.

AAI141-H50 S1 has the -H communication selection. Yokogawa documents HART digital communication for AAI141-H, allowing field-device variables to be transferred in addition to the analog 4 to 20 mA process signals.

AAI141-H50 S1 uses -H for HART communication, 5 for no explosion protection and 0 for the basic type. These selections are defined in the manufacturer ordering table; S1 is retained as supplied.

AAI141-H50 S1 supports dual-redundant operation. Yokogawa describes placing matched HART modules in adjacent odd/even slots of the same node unit; the terminal block, wiring and system engineering must suit that arrangement.

AAI141-H50 S1 supports two-wire or four-wire transmitters, with the selection set by a pin for each channel. Use the documented transmitter supply and wiring arrangement for the selected connection hardware.

AAI141-H50 S1 has a documented input accuracy of ±16 µA, a 10 ms data update period and a 100 ms step response time. The nominal signal range is 4 to 20 mA DC.

AAI141-H50 S1 accepts pressure-clamp terminal, KS cable or MIL connector-cable arrangements. The selected terminal block or cable adapter is a separate ordering choice; the supplied identifier does not include an accessory option code.
