EPS5511-2 Hazardous area MTL5511 SWITCH/ PROXIMITY DETECTOR INTERFACE Safe area To earth leakage detector Switch-type sensors require resistors if LFD is selected single channel, with line fault detection 6 5 4 680W 22kW The MTL5511 enables a safe-area load to be controlled by a switch or proximity detector located in a hazardous-area. When selected, open or short circuit conditions in the field wiring are detected by the line-fault-detect (LFD) facility and also indicated on the top of the module. Phase reversal for the channel is selected by a switch on the side of the module and output is provided by changeover relay contacts. 10 11 12 Output 13 14 Vs Vs+ 20 to 35V dc Terminal SPECIFICATION 1 2 3 10 11 12 13 14 See also common 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.
