It supports HART digital communication and uses the ATA4S-00 pressure clamp terminal block for field wiring. Its specifications include a 10 ms data update period, circuit-open detection, and defined output isolation and load resistance limits.\u003c\/p\u003e\n\u003ch3\u003eOutput Configuration and Signal Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe AAI543-H50 provides 16 isolated current output channels.

Circuit-open detection provides an indication of an open output loop when the current falls below the specified threshold.\u003c\/p\u003e\n\u003ch3\u003eHART Communication and Terminal Connection\u003c\/h3\u003e\n\u003cp\u003eThe HART-capable configuration supports digital communication over the analog current loop. This allows compatible field instruments to exchange digital information while using the 4 to 20 mA signal for the primary analog output.\u003c\/p\u003e\n\u003cp\u003eThe specified ATA4S-00 pressure clamp terminal block provides the field wiring interface. The listed external connection options also include a MIL connector cable and dedicated KS1 cable. The appropriate connection arrangement depends on the installed terminal and cable configuration.\u003c\/p\u003e\n\u003ch3\u003eRedundant Configuration and Switch-over Response\u003c\/h3\u003e\n\u003cp\u003eThe H50 configuration identifies the standard switch-over response type for redundant operation without explosion protection. In a dual-redundant arrangement, two identical AAI543 modules with the same switch-over response type are used as control and standby modules.\u003c\/p\u003e\n\u003cp\u003eDuring a control-to-standby switchover, the output may fall below 4 mA for a maximum of 100 ms. This timing is relevant when selecting the module for field devices that require continuous current output. The fast-response version has a different ordering code and should not be treated as equivalent to this standard-response configuration.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\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\u003eAAI543-H50\/ATA4S-00\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 Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Output Channels\u003c\/td\u003e\n\u003ctd\u003e16, isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e4 to 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHART Communication\u003c\/td\u003e\n\u003ctd\u003eAvailable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWithstanding Voltage\u003c\/td\u003e\n\u003ctd\u003e1500 V AC, 1 minute (output to system)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Load Resistance\u003c\/td\u003e\n\u003ctd\u003e0 to 750 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit-Open Detection\u003c\/td\u003e\n\u003ctd\u003eLess than 0.65 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-48 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\u003eAmbient Temperature Drift\u003c\/td\u003e\n\u003ctd\u003e+\/-16 uA\/10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e230 mA (5 V DC), 540 mA (24 V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003ePressure clamp terminal, MIL connector cable, dedicated KS1 cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Block\u003c\/td\u003e\n\u003ctd\u003eATA4S-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.4 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eElectrical Isolation and Load Requirements\u003c\/h3\u003e\n\u003cp\u003eThe module provides 1500 V AC withstand voltage between the output circuit and the system for one minute.

The H suffix identifies the HART digital communication version. It supports HART communication alongside the 4 to 20 mA analog output.\u003c\/p\u003e\n\u003cp\u003eQ: What is the difference between standard and fast switch-over versions?\u003c\/p\u003e\n\u003cp\u003eA: The H50 configuration uses standard switch-over response, with a maximum output drop-below-4 mA period of 100 ms during redundant switchover. The fast-response configuration uses a different suffix code and has a maximum period of 2 ms.\u003c\/p\u003e\n\u003cp\u003eQ: Which terminal block is specified for this configuration?\u003c\/p\u003e\n\u003cp\u003eA: The specified terminal block is ATA4S-00, a pressure clamp terminal block. The corresponding Yokogawa option code is \/A4S00.
