MTL5511 9V DC Safety Barrier Switch Proximity Detector Interface with Line Fault Detection
The MTL5511 safety barrier enables safe-area load control using switches or proximity detectors located in hazardous areas, providing reliable interface protection for industrial automation systems.
| Parameter | Specification |
|---|---|
| Compliance Standard | BS EN60947-5-6:2001 (NAMUR proximity detectors) |
| Sensor Voltage | 7 to 9V DC from 1kΩ ±10% |
| Input/Output Characteristics | Normal phase operation |
| Output State Conditions |
|
User-selectable via switches on the unit side. Line faults are indicated by LED and de-energize the channel output relay.
| Fault Condition | Activation Threshold |
|---|---|
| Open-Circuit Alarm | On if Iin < 50µA, Off if Iin > 250µA |
| Short-Circuit Alarm | On if Rin < 100Ω, Off if Rin > 360Ω |
Note: Resistors must be fitted when using LFD with contact input: 500Ω to 1kΩ in series with switch, 20kΩ to 25kΩ in parallel with switch.
Single pole relay with changeover contacts. Reactive loads must be adequately suppressed for optimal performance.
