EPS5511-2 Hazardous area Safe area MTL5511 SWITCH/ 1 2 PROXIMITY DETECTOR INTERFACE . / % & 0 ( single channel, with line fault detection ) &( - 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.

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 < 50A Open-circuit alarm off if Iin > 250A Short-circuit alarm on if Rin < 100 Short-circuit alarm off if Rin > 360 Note: Resistors must be fitted when using the LFD facility with a contact input 500 to 1k in series with switch 20k to 25k in parallel with switch Safe-area output Single pole relay with changeover contacts Note: reactive loads must be adequately suppressed Relay characteristics Response time: 10ms maximum Contact rating: 250V ac, 2A, cos >0.7 40V dc, 2A, resistive load The given data is only intended as a product description and should not be re- garded as a legal warranty of properties or guarantee.
