MTL4516/C, MTL5516C 2 channel isolated barriers product description:

MTL4516/C – MTL5516C SWITCH/ PROXIMITY DETECTOR INTERFACE 2-channel, with line fault detection

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.

MTL4516/C, MTL5516C 2 channel isolated barriers  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

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
