Backplane bus communication velocity handles discrete state updates within fixed scan cycles, preserving loop timing synchronization across distributed rack expansions. I\/O density scaling allows seamless integration alongside specialized analog and communication modules without violating backplane current loading limits or introducing protocol conversion latencies. Firmware flash compatibility is managed through system software tools to maintain baseline operational stability across revision changes.\u003c\/p\u003e\n\u003ch3\u003eShipment Contents \u0026amp; Package Inventory\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Allen-Bradley 1734-OV4E Digital DC Sinking Output Module\u003c\/li\u003e\n\u003cli\u003e1 x Removable Terminal Block Insert\u003c\/li\u003e\n\u003cli\u003e1 x Technical Hardware Reference Leaflet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePhysical Installation Procedures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDIN Rail Mounting\n\u003cul\u003e\n\u003cli\u003eMount the module base securely onto a standard 35 mm industrial DIN rail inside an approved electrical cabinet.\u003c\/li\u003e\n\u003cli\u003eAlign the module housing with the terminal base and snap firmly into position to engage the communication backplane.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eField Wiring Connections\n\u003cul\u003e\n\u003cli\u003eTerminate external 24 VDC load lines directly into the removable terminal block screw connections.\u003c\/li\u003e\n\u003cli\u003eRoute low-voltage output wiring away from high-voltage AC power cables to minimize electromagnetic interference.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Technical Inquiries\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQ: How many output points does this module control?\u003c\/li\u003e\n\u003cli\u003eA: The module provides 4 digital DC sinking output points.\u003c\/li\u003e\n\u003cli\u003eQ: What is the rated output voltage for the switching channels?\u003c\/li\u003e\n\u003cli\u003eA: The output voltage is rated at 24 Volts DC.\u003c\/li\u003e\n\u003cli\u003eQ: What is the maximum output current capacity per module?\u003c\/li\u003e\n\u003cli\u003eA: The total module output current rating is 3 amps.\u003c\/li\u003e\n\u003cli\u003eQ: How much current does the unit draw from the POINTBus?\u003c\/li\u003e\n\u003cli\u003eA: The POINTBus current draw is 75 milliamps.\u003c\/li\u003e\n\u003cli\u003eQ: What are the thermal and power dissipation values?\u003c\/li\u003e\n\u003cli\u003eA: Power dissipation is 1.2 Watts, resulting in a thermal dissipation of 4.1 BTU per hour.\u003c\/li\u003e\n\u003cli\u003eQ: Are the outputs electronically protected against faults?\u003c\/li\u003e\n\u003cli\u003eA: Yes, the module features built-in electronic protection for safe operation.\u003c\/li\u003e\n\u003cli\u003eQ: Does this module support live hot-swapping inside an active rack?\u003c\/li\u003e\n\u003cli\u003eA: System power must be isolated before removing or inserting modules to prevent bus arc damage.\u003c\/li\u003e\n\u003cli\u003eQ: What physical dimensions apply to the shipping container?\u003c\/li\u003e\n\u003cli\u003eA: The estimated shipping dimensions measure 8 cm x 6 cm x 1.7 cm.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":46066401018029,"sku":"1734-OV4E","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/1734-OV4E3_1_3.jpg?v=1785138258","url":"https:\/\/www.maxwellplc.com\/products\/1734-ov4e-allen-bradley-digital-dc-sinking-output-module-point-i-o","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
