PMAC**1 Motor Protection Device integrates measurement,protection,and control functions. RS**5/ Modbus,optional Profibus module.

1. Use module framework. Several modules can be selected flexibly.

Â

2. PMAC**1 provides *7 protection functions such as start overtime protection, overload protection, overcurrent protection, phase failure protection, current unbalance protection, earth fault/leakage current protection, short circuit protection, underload protection, external fault protection, overvoltage protection, undervoltage protection, under power protection, phase sequence error protection, EEx e overload protection, temperature (PTC/NTC) protection, analog protection.

Â

3. Provides measurements of three phases current, three phase /phase voltage, zero phase sequence current, active power, reactive power, power factor, frequency, and active energy measurements.

Â

4. Provides protection, direct starter, reversing direct starter, star/delta starter, and autotransformer starter etc motor starting control modes.

Â

5. Main module provides 9 DIs for start, stop and reset etc. signals . If more DIs are needed, an extended digital module can be selected. Some of the DIs are programmable.

Â

6. Main module provides 5 DOs to meet varies of starting control modes and protection action. If more DOs are needed, an extended digital module can be selected. Some of the DOs are programmable.

Â

7. Provides 4~*0mA analog output for DCS.

Â

8. 8 trip events can be stored in non-volatile memory.

Â

9. Through an extended analog module, 2 analog or 1 analog and 1 hot resistance can be added.

Â

*0. Small size and compact configuration.

Â

*1. Easy installation. Proper for *5mm DIN rail.
