Séparateur à 2 canaux MTL4517-MTL5517

The MTLx517 enables two safe-area loads to be controlled, through a relay, by proximity detectors or switches 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 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 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 Channel: Two single-pole relays with normally open contacts LFD: Single pole relay with changeover contact (MTL4517) Single pole relay with normally open contact (MTL5517)
LED indicators Green: power indication
Yellow: four: on when output active
Red: LFD indication + faulty channel’s yellow LED flashes
Maximum current consumption 35mA at 24V
Power dissipation within unit 0.84W 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


 MTL4511MTL5511
Response time Max 10 ms 10ms maximum
Contact rating (Safe Area) 10W, 0.5A, 35V DC 250V ac, 2A, cosØ >0.7, 40V dc, 2A, resistive load
Contact rating (Zone 2) 10W, 0.5A, 35V DC 35V, 2A, 100VA



SIL capable


These models have been assessed for use in IEC 61508 functional safety applications. SIL2 capable for a single device (HFT=0) SIL3 capable for multiple devices in safety redundant configurations (HFT=1).
