EPS5516C-2 Hazardous area Safe area MTL5516C SWITCH/ 1������$ �����2� PROXIMITY DETECTOR �������� &(�� INTERFACE ���� & ’ � *$�� � ( two-channel, with line fault detection � � ) &(�� �� � � �� *$�� � � 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.

Line faults 35mA at 24V are indicated by an LED for each channel. The channel output Power dissipation within unit relay is de-energised if an input line fault is detected. 0.84W at 24V Open-circuit alarm on if I < 50µA in Safety description (each channel) Open-circuit alarm off if I > 250µA in V =10.5V I =14mA P =37mW U = 253V rms or dc o o o m Short-circuit alarm on if R < 100Ω in Short-circuit alarm off if R > 360Ω in 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 Response time: 10ms maximum Contact rating: 250V ac, 2A, cosØ >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.
