The module provides physical interface translation across two RS-232 ports and one DH-485 port, enabling point-to-point and multi-drop network integration for MicroLogix and SLC 500 controllers. It operates on an input voltage range of 20.4 to 28.8 VDC with a nominal current draw of 120 mA at 24 VDC and maintains galvanic isolation tested at 500 VDC for 60 seconds.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003e1761-NET-AIC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3.00 kg (6.61 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.60 in x 4.10 in x 2.40 in (14.2 cm x 10.4 cm x 6.1 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C (32 to 140 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e2.88 W (120 mA @ 24 VDC; Max Inrush: 200 mA @ 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply DC Range\u003c\/td\u003e\n\u003ctd\u003e20.4 to 28.8 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Ports\u003c\/td\u003e\n\u003ctd\u003e2 RS-232 ports (Port 1: 9-pin D-shell; Port 2: 8-pin mini-DIN), 1 DH-485 port (6-pin Phoenix)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Protocol\u003c\/td\u003e\n\u003ctd\u003eDH-485 protocol across all serial interfaces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003eTested at 500 VDC for 60 seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHazardous Location Rating\u003c\/td\u003e\n\u003ctd\u003eUL Listed Class 1, Division 2, Groups A, B, C, D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication \u0026amp; Deterministic Processing\u003c\/h3\u003e\n\u003cp\u003eThe Allen-Bradley 1761-NET-AIC manages serial bus communication velocity across DH-485 network segments by executing hardware-level RS-232 to RS-485 signal conversions without introducing processor-level latency. Firmware flash compatibility across MicroLogix 1000\/1200\/1500 and SLC 500 host platforms ensures deterministic token-passing schedules over the DH-485 trunkline. The unit scales communication node connectivity while isolating low-level serial transceivers from common-mode ground potential shifts, preserving message packet integrity across multi-drop device layouts.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is external 24 VDC power supplied to the 1761-NET-AIC converter?\u003c\/p\u003e\n\u003cp\u003eA: Power can be supplied via the external 24 VDC screw terminal block (20.4 to 28.8 VDC) or drawn directly through the 8-pin mini-DIN RS-232 connection when connected to a host MicroLogix controller capable of providing 24 VDC bus power on Port 2.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the 500 VDC isolation rating on the 1761-NET-AIC?\u003c\/p\u003e\n\u003cp\u003eA: The 500 VDC isolation barrier separates the DH-485 network channel from the RS-232 serial ports and primary power supply leads, preventing ground loop currents and transient high-voltage surges from damaging connected controllers.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower \u0026amp; Network Disconnection\u003c\/strong\u003e: Turn off all external 24 VDC power supplies and disconnect active serial network cables before mounting or wiring the 1761-NET-AIC converter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Rail \/ Panel Mounting\u003c\/strong\u003e: Mount the module onto a 35 mm DIN rail or attach it to an enclosure backplate using mounting screws.
