MTL4511 SWITCH PROXIMITY DETECTOR INTERFACE MTL4511
Overview
The MTLx511 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 linefault-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.

MTL4511 SWITCH PROXIMITY DETECTOR INTERFACE MTL4511
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
