BASIC INFO
MTL5516C Safe Isolators SWITCH/ PROXIMITY DETECTOR INTERFACE 2-channel, with Line Fault Detection
The MTL5516/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.
SPECIFICATION
See also common 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 1kohm ±10%
Input/output characteristics
Normal phase
Outputs closed if input > 2.1mA (< 2kohm in input circuit)
Outputs open if input < 1.2mA (> 10kohm in input circuit)
Hysteresis: 200µA (650ohm) 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 < 100ohm
Short-circuit alarm off if Rin > 360ohm
Note: Resistors must be fitted when using the LFD facility with a contact input
500ohm to 1kohm in series with switch
20kohm to 25kohm in parallel with switch
Safe-area output
Two single-pole relays with changeover contacts
Note: reactive loads must be adequately suppressed
