4-channel separator MTL4510B-MTL5510B

The MTL4510B enables four solid-state outputs in the safe area to be controlled by up to four switches or proximity detectors located in a hazardous area. Each pair of output transistors shares a common terminal and can switch +ve or –ve polarity signals. A range of module configurations is available (see Table 1) through the use of selector switches. These include start/stop operations and pulse output modes.


Specificationa


Number of channels 4, configured by switches
Location of switches Zone 0, IIC, T6 hazardous area
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 – 9V DC for 1 kOhm +/- 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 via switches on the side of the unit
Open-circuit alarm on if Iin < 50 uA
Open-circuit alarm off if Iin > 250 uA
Short-circuit alarm on if Rin < 100 Ohm
Short-circuit alarm off if Rin > 360 Ohm
Safe-area outputs Floating solid-state outputs compatible with logic circuits
Operating frequency DC to 500Hz
Max. off-state voltage +/- 35V
Max. off-state leakage current +/- 50 uA
Max. on-state resistance 25 Ohm
Max. on-state current +/- 50 mA
LED indicators Green: power indication
Yellow: four: on when output active
Red: LFD indication + faulty channel’s yellow LED flashes
Maximum current consumption 40mA at 24V (with all output channels energised)
Power dissipation within unit 0.96W at 24V, with 10mA loads
Safety description (each channel) Uo=10.5V Io=14mA Po=37mW Um = 253VDC
ModeFunctionEquivalent**

4 1-ch with line fault output MTLx014
5 As mode 4 with changeover outputs  
6 1-ch with start-stop latch MTL2210B
7 As mode 2 but with LFD enabled on both inputs MTL4016
8 4-ch switch input MTLx510
9 2-ch with line fault output MTLx017
10 As mode 9 with LFD changeover  
11 As mode 10 with phase reversed
