MTL4511 – MTL5511 SWITCH/ PROXIMITY DETECTOR INTERFACE 1-channel, with line fault detection.

MTL4511 – MTL5511 SWITCH/ PROXIMITY DETECTOR INTERFACE 1-channel, with 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. A line fault is
indicated by an LED. 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 < 100Ω Short-circuit alarm off if Rin > 360Ω
Note: Resistors must be fitted when using the LFD facility with a contact input
500Ω to 1kΩ in series with switch
20kΩ to 25kΩ in parallel with switch
Safe-area output
Single pole relay with changeover contacts
Note: reactive loads must be adequately suppressed
