MTL4514 安全屏障和隔离器MTL仪器
MTL4514 SWITCH/ PROXIMITY DETECTOR INTERFACE
MTL4514
Estimated Lead Time: 7-10 Working Days Manufacturer: MTL Instruments MTL4514 MTL4514/B SWITCH/ PROXIMITY DETECTOR INTERFACE 1-channel, line fault detection, phase reversal The MTL4514 enables a safe–area load to be controlled, through a relay, by a proximity detector or switch located in a hazardous area. Number of channels: One Location of switch: 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 Hazardous–area inputs Inputs conforming to BS EN60947–5–6:2001 standards for proximity detectors (NAMUR) Voltage applied to sensor: 7 to 9V dc from 1k? ±10% Input/output characteristics Normal phase Outputs closed if input > 2.1mA (< 2k? in input circuit) Outputs open if input < 1.2mA (> 10k? in input circuit) Hysteresis: 200µA (650?) nominal Line fault detection (LFD) (when selected) User-selectable via switches on the side of the unit. Line faults are indicated by an LED. Line fault relay is energised and channel output relay de-energised if input line-fault detected Open-circuit alarm on if Iin < 50µA Open-circuit alarm off if Iin > 250µA Short-circuit alarm on if Rin < 100? Short-circuit alarm off if Rin > 360? Note: Resistors must be fitted when using the LFD facility with a contact input 500? to 1k? in series with switch 20k? to 25k? in parallel with switch Safe-area output Channel: Single pole relay with changeover contacts LFD: Single pole relay with changeover contacts Shipping Weight : 1 Kg
