• Voltage-free (dry contact) outputs — NO and NC available per channel
• Wire-break detection per channel (diagnostic bit)
• Short-circuit detection per channel (diagnostic bit)
• Hot-swap capable
• Supports both AC and DC load switching on the same module

Structural Features:

• Form Factor: 45 mm width, X20 standard
• Mounting: DIN rail 35 mm / direct screw
• Connector: X20 system bus (top)
• Terminal Type: Push-in spring clamp, 0.14 mm² to 2.5 mm²
• Housing Material: Polycarbonate (PC), UL94 V-0
• Protection Rating: IP20
• Dimensions (W × H × D): 45 mm × 90 mm × 75 mm (approx.)

Operating Conditions:

• Operating Temperature: -25°C to +70°C
• Storage Temperature: -40°C to +85°C
• Relative Humidity: 5% to 95% (non-condensing)

Applicable Industries:

• Solenoid valve control (pneumatic/hydraulic)
• Motor starter contactor control
• Alarm and indicator light driving
• Heater element switching (AC loads)
• Safety relay output replacement
• Mixed AC/DC load applications (e.g., lamp + solenoid on same module)

Installation Requirements:

• DIN rail 35 mm (EN 60715)
• Wire size: 0.14–2.5 mm² copper conductors
• For AC loads: use appropriate fuse/MCB per channel (max 2 A)
• For inductive loads: install RC snubber or varistor across load (recommended)
• Minimum 10 mm spacing between modules for heat dissipation

Usage Precautions:

• Maximum per-channel current: 2 A — do not exceed
• Maximum switching frequency: 10 operations per second (continuous), 120 operations per minute (sustained)
• Do not switch loads exceeding rated voltage (250V AC / 30V DC)
• For highly inductive loads, use external suppression to extend relay life
• Relay outputs are slower than transistor outputs — not suitable for high-speed PWM

Advantages & Highlights:

• Voltage-free relay contacts — switch AC and DC with same module
• 10 million mechanical operations — exceptional longevity
• Full galvanic isolation per channel — safe for mixed-voltage systems
• Changeover contact (NO + NC) provides flexibility for interlock circuits
