Its eight input channels are electrically isolated from one another, helping prevent electrical interference or potential differences on one field circuit from directly affecting other input channels.\u003c\/p\u003e\n\u003cp\u003eThis configuration is suitable for acquiring independent process measurements, such as transmitter current signals, where channel isolation is required. The standard -S version does not indicate the HART communication option; Yokogawa identifies -H separately for HART-equipped versions.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eOrdering Code and Configuration\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe complete ordering number identifies both the module configuration and its connection arrangement:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAAI135: 8-channel, isolated 4-20 mA analog input module.\u003c\/li\u003e\n\u003cli\u003e-S: Standard type.\u003c\/li\u003e\n\u003cli\u003e0: Basic type.\u003c\/li\u003e\n\u003cli\u003e3: ISA Standard G3 option and extended temperature option (-20 to 70 deg C).\u003c\/li\u003e\n\u003cli\u003e\/K4A00: KS Cable Interface Adapter, model ATK4A-00.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe \/K4A00 suffix identifies the specified cable interface adapter configuration.

Yokogawa specifies a withstand voltage of \u003cstrong\u003e500 V AC for 1 minute\u003c\/strong\u003e between the input and system, and between input channels. This isolation is relevant when field transmitters operate on separate electrical circuits or have different ground potentials.\u003c\/p\u003e\n\u003cp\u003eThe input circuitry supports 2-wire and 4-wire transmitter connections. For 2-wire transmitters, the module provides a minimum terminal voltage of 15.0 V at 20 mA, subject to external wiring voltage drop. The input resistance varies with signal current because of the input protection circuit.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eParameter | Specification\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eAAI135-S03\/K4A00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Isolation\u003c\/td\u003e\n\u003ctd\u003eIsolated channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Current\u003c\/td\u003e\n\u003ctd\u003e25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance\u003c\/td\u003e\n\u003ctd\u003e290 Ohm at 20 mA to 450 Ohm at 4 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-16 uA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Update Period\u003c\/td\u003e\n\u003ctd\u003e10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e15.0 V minimum at 20 mA; 29.3 V maximum at 0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e360 mA at 5 V DC; 450 mA at 24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Withstand Voltage\u003c\/td\u003e\n\u003ctd\u003e500 V AC for 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHART Communication\u003c\/td\u003e\n\u003ctd\u003eAvailable on HART-equipped version; not specified for -S type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Option\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eISA Environmental Option\u003c\/td\u003e\n\u003ctd\u003eISA Standard G3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003eKS cable interface adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdapter Model\u003c\/td\u003e\n\u003ctd\u003eATK4A-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.30 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e\u003cstrong\u003eSystem Configuration and Application\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe AAI135 belongs to Yokogawa's analog I\/O hardware for FIO systems.
