Unlike point-to-point interfaces, this module supports multi-drop network topologies using RS-422 and RS-485 protocols, enabling multiple field devices to communicate over a single balanced transmission line.\u003c\/p\u003e\n\u003cp\u003eIt serves as a reliable communication bridge between the controller and distributed devices such as motor drives, power meters, and sensors. By using differential signaling, the ACM12-S1 ensures strong noise immunity and stable data transmission even in electrically noisy industrial environments.\u003c\/p\u003e\n\u003cp\u003eWith support for data rates up to 230 Kbps, low power consumption (\u0026lt;1 W), and a wide operating temperature range, the module is well-suited for decentralized control cabinets and long-distance communication networks. Its DIN rail mounting design provides a compact and flexible installation solution.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\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 Identification\u003c\/td\u003e\n\u003ctd\u003eACM12-S1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquipment Category\u003c\/td\u003e\n\u003ctd\u003ePLC Communication Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface Protocols\u003c\/td\u003e\n\u003ctd\u003eRS-422 \/ RS-485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmission Speed\u003c\/td\u003e\n\u003ctd\u003eUp to 230 Kbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 1 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20°C to +70°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation Method\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN rail mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware Origin\u003c\/td\u003e\n\u003ctd\u003eYokogawa Electric Corporation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Architecture\u003c\/td\u003e\n\u003ctd\u003eDifferential signaling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Weight\u003c\/td\u003e\n\u003ctd\u003e0.86 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eApplication Context\u003c\/h3\u003e\n\u003cp\u003eThe ACM12-S1 is widely used in:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eFactory automation systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnergy management systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProcess industries\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt is particularly suitable for:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eModbus RTU networks\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnecting multiple variable frequency drives (VFDs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMonitoring distributed smart instruments in high-EMI environments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIts multi-drop capability makes it ideal for centralized monitoring and control of multiple devices over long distances.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow many devices can the ACM12-S1 support in a single network?\u003c\/strong\u003e\u003cbr\u003eIn a standard RS-485 multi-drop configuration, the ACM12-S1 can typically support up to 31 slave devices without a repeater.
