• Compatible with 24 VDC field devices (–15% to +30% tolerance)

• Input current ≤ 15 mA per channel under standard operation

• Ignition current < 100 mA per channel at 24 VDC +30%

• Supports redundant SDI‑1624 modules for enhanced reliability

• Safety-rated design suitable for ATEX/IECEx environments

• Screw-terminal wiring with DIN rail mounting (TS32 / TS35 × 7.5)

• Aluminum housing with efficient heat dissipation for continuous operation

• Compact footprint: 170 × 70 × 60 mm

• Weight: 0.5 kg

Applications

• Safety and control systems requiring reliable digital input acquisition

• Industrial plants with harsh environmental conditions

• Redundant digital input configurations for critical processes

• Interface for field devices such as switches, sensors, and emergency stop circuits
