MTL5018AC SWITCH/ PROXIMITY DETECTOR INTERFACE two-channel, with line fault detection and phase reversal
The MTL5018ac 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.



 MTL5018AC Intrinsically Safe Isolators product introduction
 Number of channels :Two
 Location of switches
 Zone 0, IIC, T4–6 hazardous area Div. 1, Group A hazardous location
 Safe-area outputTwo 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 10kΩ Hysteresis: 200μA, typica
 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 250μA
 Short-circuit alarm on 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 power dissipation:<2.5W
 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
 Power Supply :
  85 to 265V ac 45 to 65 Hz
