It supports data strings of up to 128 bytes and transaction IDs from 0 to 255, ensuring flexible communication with external serial devices. The module comes with a sealed M12 connector for rugged environments, provides status feedback through multiple LED indicators, and features robust electrical isolation rated at 50 Volts continuous and tested to 1250 Volts AC RMS. With a low supply current of 15 mA at 24 VDC and a maximum power dissipation of 0.75 W, it ensures energy-efficient performance while maintaining reliability across a wide operating temperature range of -20 to 60 °C.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHousing: IP67-rated design eliminates the need for protective enclosures in harsh environments.\u003c\/li\u003e\n\u003cli\u003eInput Channel: Provides one full duplex RS-232 ASCII input for direct serial communication.\u003c\/li\u003e\n\u003cli\u003eData Handling: Supports transmit strings up to 128 bytes and transaction IDs from 0 to 255.\u003c\/li\u003e\n\u003cli\u003ePower Requirements: Operates at 24 VDC nominal with a supply current of 15 mA.\u003c\/li\u003e\n\u003cli\u003eBus Consumption: Draws up to 75 mA from the 5 VDC PointBus for system integration.\u003c\/li\u003e\n\u003cli\u003eEnergy Efficiency: Maximum power dissipation of 0.75 W and thermal dissipation of 2.5 BTU\/hr.\u003c\/li\u003e\n\u003cli\u003eElectrical Protection: Isolation voltage of 50 V continuous, tested at 1250 V AC RMS for 60 seconds.\u003c\/li\u003e\n\u003cli\u003eIndicators: Includes green\/red module and network status LEDs, plus TXD\/RXD activity indicators.\u003c\/li\u003e\n\u003cli\u003eEnvironmental Ratings: Operates from -20 to 60 °C with storage capability down to -40 °C and up to 85 °C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1738-232ASCM12 delivers the reliability and precision required for distributed control systems and serial device integration in industrial automation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47095031660842,"sku":"1738-232ASCM12","price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/shopping_91_17c069e6-d6be-419e-a8ef-e7e694478ad9.webp?v=1718445414","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1738-232ascm12-armorpoint-i-o-rs-232-ascii-communication-module","provider":"IQElectro","version":"1.0","type":"link"}
