Details

Basic Characteristics:
- Number of Channels: Single-channel.
- Application Occasions:
  - Switches can be used in Zone 0, IIC Group, T6 hazardous areas, and Division 1, Group A hazardous areas.
  - Proximity switches, if properly certified, can be used in Zone 0, IIC Group, T4-T6 hazardous areas, and Division 1, Group A hazardous areas.
- Output Type: One relay with changeover contacts.
- Input Standard: Hazardous area input complies with NAMUR/DIN 19234 standard, suitable for proximity switches.
- Sensor Power Supply: Provides 7V to 9V voltage starting from 1kΩ±10%.
Input and Output Characteristics:
- Normal (Inverted) Phase:
  - If input current Iin > 2.1mA or input resistance Rin < 2kΩ, the output is energized (de-energized).
  - If Iin < 1.2mA or Rin > 10kΩ, the output is de-energized (energized).
- Hysteresis: Typical value 200μA.
- Line Fault Detection (LFD): User-selectable, set via the switch on the top of the device.
  - When Iin < 100μA, open-circuit alarm is triggered.
  - When Iin > 250μA, no open-circuit alarm.
  - When Rin < 100Ω, short-circuit alarm is triggered.
  - When Rin > 360Ω, no short-circuit alarm.
  - When using the LFD function, a 500Ω to 1kΩ resistor must be connected in series with the contact input, and a 20kΩ to 25kΩ resistor in parallel.
- Inversion: User-selectable via the switch on the top of the device.
Relay Characteristics:
- Type: Single-pole changeover (SPDT).
- Response Time: Maximum 10ms.
- Contact Rating: 250V AC, 2A, cosα > 0.7; 40V DC, 2A, resistive load.
Display Function:
- Green LED: Power indicator.
- Yellow LED: Channel status indicator, lights up when the output is energized.
- Red LED: LFD indicator, lights up when a line fault is detected.
Electrical Parameters:
- Maximum Current Consumption: 40mA at 20V, 35mA at 24V, 25mA at 35V.
- Maximum Power Consumption: 0.75W at 24V, 0.8W at 35V.
- Isolation: 250V AC or DC insulation between power supply, hazardous area circuits, and relay outputs.
- Safety Description: Each channel is 10.5V, 800Ω, 14mA, Um = 250V rms or DC.
Other Features:
- Adopts DIN rail mounting, with pluggable terminals for easy installation and maintenance.
- Equipped with output polarity inversion function, complies with functional safety specification IEC61508, and can provide products with SIL (Safety Integrity Level) certification.
