Short Description
Description:
The 1756-OC8 is an 8-point DC digital output module developed for ControlLogix® systems, particularly for applications that require higher voltage source outputs.
It operates in the 30-60V DC range, making it appropriate for industrial applications where 48V DC is commonly used, such as automotive, heavy machinery, and energy systems.
Each output is divided into four groups, and the module provides 2 A per channel, allowing it to power high-current loads such as solenoids, contactors, and actuators.
For field wiring, the module uses a 20-pin RTB (Removable Terminal Block) and connects neatly into the ControlLogix chassis.
Hot-Swappable: Yes, replace while the power is on.
Status indicators include individual LEDs for each output.
Diagnostics: basic fault detection.
Backplane current draw: around 165 mA at 5 V DC.
Power dissipation is ~2.5 W maximum.
