MTL5018 MTL Instruments Proximity Detector Interface Number Of Channels 2

Product Specification

MTL5018 MTL Instruments Proximity Detector Interface
 
The MTL5018 enables two safe-area loads to be controlled by two
switches or proximity detectors located in a hazardous area. Two
relay outputs are provided. Independent phase reversal control allows
an alarm condition to be signalled for either state of the sensor. A
selectable line fault detect (LFD) facility detects an open or short
circuit in either field circuit.

• 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
• Safe-area output
     Two relays with changeover contacts
• Hazardous-area inputs
     Inputs conforming to NAMUR/DIN 19234 standards for proximity detectors
• Voltage applied to sensor
     7 to 9V from 1kΩ ±10%
• Input/output characteristics
     Normal (reverse) phase:
           output energised (de-energised) if Iin >2.1mA or Rin <2kΩ
           output de-energised (energised) if Iin <1.2mA or Rin >10kΩ
     Hysteresis: 200µA, typical
• Line fault detection (LFD)
     User-selectable via switches on the top of the unit. Line faults are indicated by an LED for each channel. A detected line fault de-energises the       relay.
     Open-circuit alarm on if Iin<100µA
     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
• Phase reversal
     Independent for each channel, user-selectable
• Relay type
     Single pole, 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
• LED indicators
     Green: power indication
     Yellow: two: status of each channel (on when outputs are energised)
     Red: two: LFD indication for each channel (on when line fault detected)
• Maximum current consumption
     60mA at 20V
     60mA at 24V
     40mA at 35V
• Maximum power dissipation
     1.4W at 24V
     1.5W at 35V
• Isolation
     250V ac or dc between power supply, hazardous-area circuits and relay outputs
• Safety description (each channel)
     10.5V, 800Ω, 14mA, Um= 250V rms or dc
