Product Overview
When a MicroLogix panel loses an I/O card, every hour of downtime costs money. The Allen-Bradley 1762-IQ8OW6 is a MicroLogix combination I/O module that packs Eight (8) sink/source DC inputs and Six (6) Form A relay outputs into one compact unit. Instead of stocking two separate cards, you get discrete input and relay output control in a single slot — a practical choice for oil, gas, and industrial automation panels that need fast replacement without redesign.
This module belongs to the MicroLogix family and is compatible for use with MicroLogix 1100 and 1200 controllers. Oil AutoTech supplies ready-to-ship spares for exactly these situations, with hands-on technical selection help if you need to confirm compatibility before ordering.
Key Specifications That Matter
Input side
The 1762-IQ8OW6 provides Eight (8) inputs split into Two (2) groups of Four (4) channels each. Inputs accept 10–30 VDC, with a nominal rating of 24 VDC. Each channel supports both sink and source wiring, so you can match existing field-device conventions without adding interface hardware. Rated signal delay is 8 ms for both ON-to-OFF and OFF-to-ON transitions — predictable enough for standard machine control and pilot-device monitoring.
Output side
Six (6) Form A (Normally Open) relay outputs handle 5–265 VAC and 5–125 VDC. Contact ratings are 2.5 A at 240 VAC or 120 VAC, 1.0 A at 125 VDC, and 2.0 A at 24 VDC. Maximum continuous current per common and per module is 8 A. Relay switching delay is 10 ms for both transitions. Because these are true dry-contact relays, they can switch AC and DC loads directly — useful for solenoids, lamps, and interposing circuits.
Power and physical data
Backplane current draw is 110 mA at 5 VDC and 80 mA at 24 VDC. Heat dissipation is 5.0 W at 30 V and 4.4 W at 26.4 VDC. The module measures 90 x 40.4 x 87 mm (3.54 x 1.59 x 3.43 in.), with 110 mm (4.33 in.) height including mounting tabs, and weighs approximately 280 g (0.62 lbs.). Power supply distance rating is Six (6) modules — it cannot sit more than six slots from the power supply.
Where It Fits
In oil and gas skids, the 1762-IQ8OW6 typically reads limit switches and pressure pilots on the input side while driving small solenoid valves or indicator lamps through its relay outputs. In water treatment and packaging lines, the same mix of DC sensing and AC switching keeps panel builds simple. If you are upgrading an older MicroLogix 1200 panel, this combination module often replaces two single-function cards and frees a slot.
Integration and Selection Notes
The module uses Three (3) I/O groups: Group 1 covers inputs 0–3, Group 2 covers inputs 4–7, and Group 3 contains all output channels. Before ordering, confirm your controller model, available slot position relative to the power supply, and whether your field devices are sinking or sourcing. Oil AutoTech can help verify these details quickly so the right module ships the first time.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
FAQs
What controller families work with the 1762-IQ8OW6?
It is compatible for use with MicroLogix 1100 and 1200 controllers.
Can the inputs be wired as either sink or source?
Yes. All Eight (8) inputs support both sink and source configurations.
What loads can the relay outputs switch?
The Six (6) Form A relay outputs operate from 5–265 VAC and 5–125 VDC, with contact ratings up to 2.5 A at 240 VAC or 120 VAC.
How far from the power supply can this module be installed?
The power supply distance rating is Six (6) modules, so it must stay within six slots of the supply.
What is the backplane current draw?
110 mA at 5 VDC and 80 mA at 24 VDC.
