Product Description

The vintage 2003-released 7DO138.70 delivers 8 robust 0.5A 24VDC outputs for industrial automation tasks. It features built-in short circuit proofing and thermal overload protection to safeguard the discreet channels from hazards. The module screws directly into control cabinets for simple installation. With its tight 3 inch by 4 inch by 1 inch dimensions and lightweight 0.1 kilogram chassis, the 7DO138.70 fits conveniently on dense DIN rails near PLC equipment. Each of the 8 outputs provides a 0.5 Amp maximum load capacity when powered by a 24 Volt DC source. This permits controlling a range of field devices like solenoid valves or small actuators.

The modules overcurrent protection trips when any output exceeds the current rating. This prevents failure by avoiding overheating damage to components. Further thermal monitoring engages to shut off channels in an over-temperature event adding an extra layer of reliability. By using robust screw-in torque-limited connections, the 7DO138.70 resists vibration and shocks compared to snap-in modules. This screw mounting gives superior durability in harsh industrial settings prone to extreme mechanical stress. Installers simply fasten the device onto 35mm DIN rail or directly against equipment.

Built by B&R Automation in 2003, the 7DO138.70 utilizes quality components to achieve an estimated 30,000 hour lifetime. The outputs switch up to 100 times per second for responsive automation control. Onboard LED status indicators confirm channel operation. With its rugged legacy design focused purely on function, the 7DO138.70 delivers essential protection features in a space-saving yet affordable package. The uncomplicated module suits cost-sensitive applications needing basic 24 Volt DC actuation capabilities paired with electrical safeguarding.
