Buy now: Allen-Bradley 1762-OB32T High-Density MicroLogix Output Module
Atlantechdrives provides you the 1762-OB32T, an ultra-high-density 32-point digital DC sourcing output module for the MicroLogix expansion platform. This module is the definitive solution for large-scale automation where chassis space is extremely limited, allowing you to double the number of outputs in a single expansion slot compared to standard 16-point modules.
- Outputs: 32 Digital DC Sourcing Outputs
- Connection Type: MIL-type Header (Requires specialized cable)
- Current per Point: 0.2A @ 55°C
- Voltage: 24V DC Sourcing (20.4V to 26.4V DC)
- Bus Draw: 175 mA @ 5V DC
Technical Superiority: Maximizing Space with 32 Points
The 1762-OB32T is engineered for high-performance systems requiring massive I/O counts in a compact footprint. By utilizing high-efficiency internal circuitry, it packs 32 independent 24V DC sourcing outputs into the same physical dimensions as standard 8 or 16-point modules. To manage this density, the 1762-OB32T uses a specialized MIL-type (ribbon cable) connector instead of standard screw terminals. This architecture allows for pre-fabricated cables to be connected to remote terminal blocks, significantly reducing cabinet assembly time and potential wiring errors. This module is ideal for high-speed material handling, automated storage systems, and complex assembly cells where dozens of pilot lights and small solenoids must be controlled simultaneously.
Installation Advice: Wiring Density and Power Management
The 1762-OB32T draws significantly more current (175mA) from the MicroLogix 5V DC bus than lower-density modules. When designing your system, always use the «MicroLogix Power Communication» tool to ensure your controller’s power supply can handle the total load of all attached expansion modules. Overloading the bus will lead to intermittent processor resets or communication faults. For wiring, we recommend using a 1762-CBL-x series cable to connect the module to an external 1492-series wiring interface. This not only makes the cabinet look cleaner but also facilitates much faster troubleshooting, as you can probe signals at the remote terminal block rather than the cramped PLC slot.
Maintenance and Connector Reliability
Maintenance for the 1762-OB32T focuses on the integrity of the MIL-type connector. Unlike screw terminals, these connectors can be sensitive to metallic dust or moisture infiltration. Ensure the cabinet environment is clean and that the cable latches are fully engaged. During routine inspections, check the «Module Fault» bit in Studio 5000 or RSLogix 500. The 1762-OB32T provides 32 status LEDs; if an entire group of 16 outputs fails, it is usually an indicator of a lost common reference in the field power distribution or a loose MIL connector. By sourcing authentic 1762-OB32T modules from Atlantechdrives, you ensure your high-density automation systems remain reliable and easy to maintain.
FAQs
Q: Does the 1762-OB32T come with screw terminals?
A: No, it features a high-density MIL connector. You will need a specialized cable and a remote terminal block for wiring.
Q: Can it drive high-current solenoids?
A: Each point is limited to 0.2A. For loads higher than this, you should use interposing relays or the 1762-OB16 (0.5A per point).
