龙岩 MTL MTL2213工控备件DCS系统电源模块

MTL2213支持控制三个10OVA安全区负载独立由三个轻型开/关开关或认证接近危险区域的探测器。开关和接近探测器可能是混合的。三个输入电路相互连接，但完全浮动。对于近端检测器和一些开关应用，相位反转-链接允许警报条件的信号为任何状态传感器。“报警”是指继电器的开/关触点断电开放，这三条赛道必须以同样的方式运行。这紧凑的低成本单元适用于各种各样的应用。的MTL2213取代了直接替代的MTL2212，除了只有8号终端可以用来连接地球。

规范参见“通用规范”通道数量三，相互连接，完全漂浮开关位置0区、IIC区、T6危险区第 一组，A组，危险地点接近探测器的位置Zone 0,llC,T4-T6(如适当认证)

第 一组，A组，危险地点施加于每个传感器的电压7.7到9.0V dc从1kQ2输入/输出特性(每个通道)

如果传感器电路中>2.1mA*(<2kQ)，则继电器通电如果传感器电路中<1.2mA*(>10kQ)继电器断电迟滞:200uA (650Q)标称

*接近探测器的NAMUR和DIN19234标准相位反转装置所有3个继电器的操作通过连接端子7和8反转电源故障保护所有三个继电器都关闭，如果电源故障，触点打开断线保护(每个通道，仅正常相位)

The MTL2213 supports control of three 10OVA safe zone loads independently by three lightweight on/off switches or certified detectors approaching hazardous areas. The switch and the proximity detector may be mixed. The three input circuits are interconnected but completely floating. For near-end detectors and some switching applications, phase-inverse-linking allows the alarm condition of the signal for any state sensor. "Alarm" means the relay's on/off contacts are off and open, and all three tracks must operate in the same way. This compact, low-cost unit is suitable for a wide variety of applications. The MTL2213 replaces the direct replacement MTL2212, except that only Terminal 8 can be used to connect to Earth.

Specifications refer to the "General Specification" Number of channels three, interconnected, fully floating switch Position Zone 0, IIC Zone, T6 Danger Zone Group 1, Group A, Danger site close to the detector location Zone 0,llC,T4-T6(if properly certified)

Group 1, Group A, hazardous location voltage applied to each sensor 7.7 to 9.0V dc from 1kQ2 input/output characteristics (per channel)

If the sensor circuit is >2.1mA*(<2kQ), the relay is energized. If the sensor circuit is <1.2mA*(>10kQ), the relay power failure hysteresis :200uA (650Q) nominal

* Operation of all 3 relays in the NAMUR and DIN19234 standard phase reversal device near the detector by connecting terminals 7 and 8 reverse power failure protection All three relays are off, if the power fails, the contacts open break line protection (per channel, normal phase only)
