Product Summary (150 - 200 Characters)
The 1762-OW8 relay output module expands your MicroLogix control system with eight robust channels. It switches AC/DC loads up to 2.5 A per point. This rackless design reduces inventory and boosts system flexibility for demanding industrial applications.
Product Procurement & Buyer Guide
Selecting the Right Output Module
The 1762-OW8 provides eight normally-open relay outputs. It works with MicroLogix 1100, 1200, and 1400 controllers. These relays offer electrical isolation between groups. This design prevents fault propagation across your system.
Engineers choose this module for its AC/DC voltage flexibility. It operates from 5 to 265 Volts AC. It also operates from 5 to 125 Volts DC. This wide range covers global industrial power standards. You can drive both 120VAC solenoids and 24VDC indicators.
Understanding Current Ratings
Each individual output point handles a continuous current of 2.5 A. The maximum continuous current per common pin is 8 A. The total continuous current for the entire module is 16 A. Match your load currents to these limits for reliable operation.
The module has two isolated output groups. Group 0 includes channels 0 through 3. Group 1 includes channels 4 through 7. You can power these groups from separate supplies. This feature enables mixed voltage applications safely.
Solving Common Industrial Pain Points
Procurement managers value the reduced spare parts inventory. One module covers many different voltage requirements. This reduces the number of unique parts you must stock. Application engineers benefit from the fast 10 ms signal delay. This delay applies to both ON and OFF transitions.
The module drives magnetic contactors and relay coils reliably. It also energizes solenoid valves and pilot lamps. Use it to signal RUN commands for Variable Frequency Drives. It works perfectly for alarm annunciator panels and sirens.
Step-by-Step Installation Guide
Preparing for Mounting
The 1762-OW8 mounts on standard DIN rails. Use type EN 50 022 35 x 7.5 mm rails. Alternatively, use EN 50 022 35 x 15 mm rails. The module weighs only 228 grams. Handle it by the body and avoid touching the circuit board.
Always install this module in a Pollution Degree 2 environment. Keep the area clean and dry. Debris falling into the module can cause permanent damage. Use DIN rail end anchors for high vibration locations. Choose panel mounting for extreme shock conditions.
Connecting to the System
Place the module six slots away from the host power supply. This distance rating ensures proper bus power delivery. Connect the ribbon cable to the adjacent expansion module. Alternatively, connect it directly to the MicroLogix base controller.
The ribbon cable carries the bus signals and power. Ensure the connector is fully seated and latched. The module draws 80 mA at 5 Volts DC. It also draws 90 mA at 24 Volts DC. Verify your system power budget includes these values.
Wiring the Output Channels
Wire each output point as a normally-open relay contact. The contacts are dry and require external power. Connect your load between the common terminal and the output terminal. Use the correct wire gauge for 2.5 A continuous current.
Group your wiring by output groups. Keep channel 0 to 3 wiring separate from channel 4 to 7. This separation maintains isolation between groups. Torque terminal screws to the manufacturer's specified value. Loose connections generate heat and reduce reliability.
