MTL4516 MTL4516C MTL5516C Switch Proximity Detector Interface

MTL4516 MTL4516C MTL5516C Switch Proximity Detector Interface

The MTL5516C enables 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 line-fault-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 MTL4516C MTL5516C Switch Proximity Detector Interface

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
