The module supports both 2-wire and 3-wire transmitters, passes bi-directional HART communication, and delivers two replicated current outputs for connection to separate control system loads.\u003c\/p\u003e\n\u003ch3\u003eSignal Interface Functions\u003c\/h3\u003e\n\u003cp\u003eThe MTL5544D accepts signals from a single field transmitter and transfers the process current signal to two independent safe-area outputs. This arrangement allows one transmitter signal to be shared by multiple receiving devices without requiring additional signal-splitting hardware.\u003c\/p\u003e\n\u003cp\u003eThe module supports standard 4-20 mA instrumentation loops and can be used with either 2-wire or 3-wire transmitter configurations.\u003c\/p\u003e\n\u003ch3\u003eDual Output Capability\u003c\/h3\u003e\n\u003cp\u003eThe output stage provides two replicated safe-area current outputs. Each output can drive loads from 0 Ohm to 450 Ohm at 20 mA, enabling connection to PLC analog inputs, DCS analog input channels, recorders, indicators, or other monitoring equipment.\u003c\/p\u003e\n\u003cp\u003eThe duplicated outputs allow process signals to be distributed to separate systems while maintaining isolation from the hazardous-area field circuit.\u003c\/p\u003e\n\u003ch3\u003eHART Communication Support\u003c\/h3\u003e\n\u003cp\u003eThe MTL5544D supports bi-directional HART communication for compatible 2-wire HART transmitters. This allows device configuration, diagnostics, and digital communication to coexist with the analog 4-20 mA measurement signal.\u003c\/p\u003e\n\u003cp\u003ePreserving HART functionality enables maintenance personnel to access transmitter information without disconnecting the measurement loop.\u003c\/p\u003e\n\u003ch3\u003ePower and Installation\u003c\/h3\u003e\n\u003cp\u003eThe module operates from a 20 VDC to 35 VDC power supply and draws a maximum current of 96 mA at 24 VDC. Typical power consumption is approximately 1.4 W.\u003c\/p\u003e\n\u003cp\u003eInstallation is on a standard 35 mm DIN rail, making the module suitable for control cabinet mounting alongside other signal-conditioning and interface devices.\u003c\/p\u003e\n\u003ch3\u003eFunctional Safety\u003c\/h3\u003e\n\u003cp\u003eThe MTL5544D is suitable for use in functional safety applications. The module is certified for SIL 2 operation in single-channel applications and can be used in SIL 3 architectures when installed in appropriate redundant configurations.\u003c\/p\u003e\n\u003cp\u003eThese ratings make the module suitable for integration into safety-related instrumented systems where certified signal isolation and transmission are required.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"___1vyiefv f1ddd56o f16vktn6 f1ahpp82 f11qra4b f1uinfot fibjyge fvueend f9yszdx f1fu4s3n f3l3pb3 f10ghnd0 f8fmt76 fjvbh62 f1qrqxae f1vw5qpk fc02sbz fxawf59 fymf513 f1aoyrul f1el8yx3 f1pymoxg f1ofu761 fe6itr f7coize f1794535 f1o0pw0q fbjjl9v fk1v6el f16pyhcb f1ixlhx9 f12zef0i flu5r5u f19haqzy f1owmcxx f1oddm8q f1004tna fcoaxci fh0ee9u f15v23i2 f1dmj53 f1r1gcv9 f14z1veh ffufd3x f1ypplot f1660cg\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eMTL5544D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eMTL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRepeater Power Supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Transmitters\u003c\/td\u003e\n\u003ctd\u003e2-wire and 3-wire 4-20 mA transmitters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e2 replicated safe-area current outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Load\u003c\/td\u003e\n\u003ctd\u003e0 Ohm to 450 Ohm @ 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHART Communication\u003c\/td\u003e\n\u003ctd\u003eBi-directional HART supported\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e20 VDC to 35 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003eMaximum 96 mA @ 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eApprox. 1.4 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Safety\u003c\/td\u003e\n\u003ctd\u003eSIL 2 (single use), SIL 3 (redundant configuration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eFSM certified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 deg C to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eApplication Considerations\u003c\/h3\u003e\n\u003cp\u003eThe MTL5544D is intended for analog process instrumentation loops requiring intrinsic safety isolation and signal duplication.
