- Nhà sản xuất : MTL Instruments
- Product No. : MTL4516
- Product Type : Switch / Proximity Detector Interface
- Number of channels : Two
- Location of switches
Zone 0, IIC, T6 hazardous area
Div. 1, Group A hazardous location
- Location of proximity detector
Zone 0, IIC, T4–6 hazardous area if suitably certified
Div. 1, Group A hazardous location
- Hazardous-area inputs
Inputs conforming to BS EN60947–5–6:2001 standards for proximity detectors (NAMUR)
- Voltage applied to sensor : 7 to 9V dc from 1k? ±10%
- Input/output characteristics
- Normal phase
Outputs closed if input > 2.1mA (< 2k? in input circuit)
Outputs open if input < 1.2mA (> 10k? in input circuit)
- Hysteresis : 200µA (650?) nomina
- Normal phase
- Line fault detection (LFD) (when selected)
User-selectable via switches on the side of the unit. Line faults are indicated by an LED for each channel. The channel output relay is de-energised if an input line fault is detected.
Open-circuit alarm on if Iin < 50µA
Open-circuit alarm off if Iin > 250µA
Short-circuit alarm on if Rin < 100?
Short-circuit alarm off if Rin > 360?
- Safe-area output : Two single-pole relays with changeover contacts
- Maximum current consumption : 35mA at 24V
- Power dissipation within unit : 0.84W at 24V
- LED indicators
Green: power indication
Yellow: two: channel status, on when output energised
Red: two: LFD indication, on when line fault detected
- Safety description (each channel) : Uo=10.5V Io=14mA Po=37mW Um = 253V rms or dc
- Dimensions ( D x W x H ) : 1.58 cm x 10.98 cm x 12.36 cm
- Cân nặng : Approx. 0.11 Kg
- Khối lượng đóng gói : 1.5 Kg
