PQMII-C-A PQMII-T20 GE Module Parts Power Quality Meter Options
GE Multilin PQMII-C-A and PQMII-T20 — Power Quality Meter Options
The GE Multilin PQM II is a multifunction power quality meter designed for monitoring electrical distribution systems, measuring power and energy, and supporting industrial power management.
The model designations PQMII-C-A and PQMII-T20 represent different option combinations of the same basic PQM II meter — they are not two separate product families. The key distinction is that C adds programmable control I/O, A adds power quality analysis, and T20 adds analog transducer outputs and an additional RS485 port.
- PQMII-C-A: Basic PQM II meter with the Control option and Power Analysis option.
- PQMII-T20: Basic PQM II meter with the T20 Transducer option.
- PQMII-T20-C-A: Combines all three options, providing expanded measurement, control, analog I/O, and power analysis functions.

Q1: What is the difference between PQMII-C-A and PQMII-T20?
PQMII-C-A includes the Control and Power Analysis options. PQMII-T20 includes the Transducer option, which provides four isolated analog outputs, one analog input, and an additional RS485 port.
Q2: Can PQMII-T20 connect to a PLC?
Yes. Its four isolated analog outputs can be assigned to measured electrical parameters and connected to compatible PLC analog inputs.
Q3: Does PQMII-C-A support harmonic analysis?
Yes. The A Power Analysis option includes harmonic analysis and other power quality recording functions.
Q4: How many additional relays are provided by the C option?
The C option adds three programmable dry-contact Form C output relays and four programmable switch inputs.
Q5: What communication interfaces are available?
The basic PQM II provides one RS485 and one RS232 port. The T20 option adds a second RS485 port.
