MTL4521/L – MTL5521 SOLENOID/ ALARM DRIVER loop-powered, IIC The MTLx521 and the MTL4521L are loop-powered modules which enable a device located in the hazardous area to be controlled from the safe area. They can all drive a certified intrinsically safe low-power load, as well as non-energy-storing simple apparatus such as an LED.

                                 
MTL5521 product specification
Number of channels ：Two
Location of switch
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 1kΩ ±10% Input/output characteristics
Normal phase
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 by switches on the side of the module. Line faults are indicated by the LED for each channel. Line fault relay is energised and channel output relay de-energised if input line-fault 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
Channel: Two single-pole relays with normally open contacts
LFD: Single pole relay with changeover contact (MTL4517) Single pole relay with normally open contact (MTL5517)
Note: reactive loads must be adequately suppressed
Maximum current consumption
35mA at 24V
Power dissipation within unit
0.84W at 24V
LED indicators
Green: power indication
Yellow: two: channel status, on when output energised
Red: two: LFD indication, on when line fault detected Safety description (each channel) Uo=10.5V Io=14mA Po=37mW Um = 253V rms or dc
