PLS480A工业自动化与控制的监控器-继电器输出规格书PDF中文资料

PLS480A属于工业自动化与控制的监控器-继电器输出。由力特公司制造生产的PLS480A监控器 - 继电器输出继电器输出监控器检测工业继电器的异常输出，并触发逻辑输出或触头组。常见的检测类型包括：AC 和 DC 电流或电压、电压不对称、接地故障、温度监控、缺相，以及相位序列或不平衡。这些器件可根据跳闸范围、延迟时间、供电电压、安装类型和开关电路进行选择。

描述 Description

The PLS Series is a low cost phase sensitive control that

provides an isolated contact closure when the proper A-B-C

phase sequence is applied. Protects sensitive 3-phase

equipment and equipment operators from reverse rotation.

Designed to be compatible with motor overloads or other

3-phase equipment protection devices. Protection for equipment

control centers where frequent reconnection or electrical code

makes reverse rotation protection essential. Examples include:

mobile refrigerated containers, construction equipment, hoists,

pumps, conveyors, elevators and escalators.

Operation

The internal relay and LED are energized when the phase

sequence is correct. The output relay will not energize if the

phases are reversed. Reset is automatic upon correction of

the fault.

FEATURES BENEFITS

Continuous monitoring

Cost effective protection of 3-phase equipment and

operators from reverse rotation. Meets reverse

rotation protection code requirements.

Universal motor

compatibility

Designed to be compatible with motor overloads or

other 3-phase equipment protection devices
