Product introduction
MTL MTL5018AC SWITCH PROXIMITY DETECTOR INTERFACE MTL5018AC
Overview
Overview
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.
SPECIFICATION
See also common specification
Number of channels
Two
Location of switches
Zone 0, IIC, T4–6 hazardous area
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 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
