1-канальный сепаратор MTL4514 / B-MTL5514

The MTLx514 enables a safe–area load to be controlled, through a relay, by a proximity detector or switch located in a hazardous area. Line faults are signalled through a separate relay and indicated on the top of the module. Switches are provided to select phase reversal and to enable the line fault detection.

Specification


Number of channels One
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 1kΩ ±10%
Input/output characteristics Normal phase:
• Outputs closed if input > 2.1mA (< 2kΩ in input circuit)
• Outputs open if input < 1.2mA (> 10kΩ in input circuit)
Hysteresis: 200μA (650Ω) nominal
Line fault detection (LFD) (when selected)* User-selectable via switches on the side of the unit
Open-circuit alarm on if Iin < 50 uA
Open-circuit alarm off if Iin > 250 uA
Short-circuit alarm on if Rin < 100 Ohm
Short-circuit alarm off if Rin > 360 Ohm
Safe-area output MTL4514 [&] MTL5514 Channel: Single pole relay with changeover contacts LFD: Single pole relay with changeover contacts MTL4514B Channel: Single pole relay LFD: Single pole relay
LED indicators Green: power indication
Yellow: four: on when output active
Red: LFD indication + faulty channel’s yellow LED flashes
Maximum current consumption 25mA at 24V dc
Power dissipation within unit 0.6W at 24V
Safety description (each channel) Uo=10.5V Io=14mA Po=37mW Um = 253V rms or dc

(*) Resistors must be fitted when using the LFD facility with a contact input:
500 Ohm to 1kΩ in series with switch
20 kOhm to 25kΩ in parallel with switch
(**) Note: reactive loads must be adequately suppressed.

Relay characteristics


 MTL4514/BMTL5514
