Key Features

• High-Density Decoupling:​ 32 diodes​ in a single 90mm module​ save space and simplify wiring for multi-channel I/O protection.

• Inductive Load Protection:​ Acts as a freewheeling diode​ to suppress voltage spikes from relays, contactors, and solenoids, protecting sensitive output cards.

• Signal Isolation:​ The common anode​ configuration allows for electrical decoupling of signals in fault reporting or dual-channel control systems.

• Tool-Free Mounting:​ Designed for DIN rail mounting​ with push-in marking slots​ and compatibility with EMG marking accessories.

Applications

• PLC Output Protection:​ Protecting transistor outputs from back-EMF when driving inductive loads like relays and small solenoids.

• Safety Circuit OR-Logic:​ Implementing OR-ing logic​ in safety relay circuits or dual-channel monitoring systems where signal isolation is required.

• Signal Conditioning:​ Decoupling digital signals in control panels to prevent ground loops or cross-talk between different I/O modules.
