Eaton MTL4516/C-MTL5516C Switch/ Proximity Detector Interface 2-channel with line fault detection MTL Intrinsic Safety Intrinsically Safe Isolators MTL5500 range

2ch DI with changeover relay output

The MTLx516/C enable two safe-area loads 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 linefault-detect (LFD) facility and also indicated on the top of the module.

Phase reversal for each channel is selected by a switch on the side of the module and output is provided by changeover relay contacts.

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. 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 < 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

Two single-pole relays with changeover contacts

Note: reactive loads must be adequately suppressed

Relay characteristics

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
