Key Features

• 48 isolated DI channels: Opto‑coupler isolation, 24 Vdc logic, compatible with dry contacts or active 24 V signals.

• On‑board 24 Vdc supply: Provides isolated 24 Vdc / 0.3 A for contact sensors, reducing external power needs.

• High noise immunity: Galvanic isolation between channels and system ground, suppressing EMI/RFI in harsh environments.

• LED status indicators: Each channel has an LED for quick on‑site troubleshooting.

• Industrial temperature range: −40 °C to +85 °C, meets MIL‑STD‑810G vibration/shock standards.

• SIL2 safety compliance: Suitable for safety‑related control loops in power and oil/gas applications.
