The Allen-Bradley 1746-OV16 is a robust discrete sinking output module. It integrates directly into the SLC 500 system. This module provides sixteen output channels for reliable DC load control. It energizes relay coils, indicators, and sounding devices effectively. The 1746-OV16 operates within a 10-50 VDC voltage range.
Product Procurement & Buyer Guide
High-Current Output Capabilities
This module handles demanding applications with its high-current design. Each point delivers 0.50 A at 30 °C. The total module current reaches 8.0 A at that temperature. You can drive multiple heavy loads from one single module. This reduces the total number of modules needed. It simplifies your control panel layout significantly.
Technical Specifications for Engineers
The 1746-OV16 uses a sinking wiring configuration for its outputs. It draws only 0.270 A from the backplane at 5VDC. The signal delay is extremely fast for critical processes. The On-state delay is just 0.1 ms for resistive loads. This speed ensures precise timing for your automation sequence.
Installation and Wiring Ease
The module comes with a pre-installed removable terminal block. You can remove this block for faster and easier wiring. This design simplifies modifications and reduces installation downtime. The module fits into a single slot of an SLC 500 chassis. It attaches directly to the modular style hardware without extra tools.
Thermal Management and Derating
Proper thermal management ensures long-term reliability for your system. The module derates its output current at higher temperatures. At 60 °C, each point delivers 0.25 A continuously. The total module current drops to 4.0 A at this temperature. You must account for this derating in your system design.
Surge Current and Protection
The 1746-OV16 handles inrush currents from inductive loads effectively. Each point can manage a surge of 3.0 A for 10 ms. This surge is repeatable every 1 second at 30 °C. It provides robust protection for starting relay coils and solenoids. The module also has a maximum Off-state leakage of only 1 mA.
