MicroPAQ AC Primary Network Monitoring

Analog Input Expansion for MicroPAQ-940P and ePAQ-9410/20/25

The MicroPAQ-940AC Analog Input Module is an I/O Expansion Module that is part of the QEI family of Distribution Automation Products.

It is a microprocessor-based electrical assembly, providing analog measurement capability to the MicroPAQ-940P and ePAQ-9410/20/25 products.

The seven analog points are arranged as two groups of three points on TB1, and four points on TB2.  For AC applications, the AC analog inputs connect directly to external sensors, CT’s and PT’s, without the need for transducers, making the inputs transducer-less.

A bank of 8 dip switches on each module allows for addressing of up to 256 modules, for a total capacity of up to 2048 analog points (256 x 8). LED indicators are included for unit diagnostics, and RS-422 communications.

Power input to the MicroPAQ-940AC is via pins on the RS-422 RJ45 jacks. Power is provided by the MicroPAQ-940P or ePAQ-9410/20/25 backbone port, or via a separate power supply.

What Our Customers Have to Say

“Our relationship with QEI began in 1986 with the deployment of a PDP-11 based SCADA system and four RTUs. Over the decades, that system has been continuously upgraded and expanded to support the growing needs of our rail operations. QEI’s solutions have provided the real-time visibility, control, and reliability required for mission-critical traction power infrastructure. With hundreds of field RTUs installed and control houses to advanced master station software, QEI has remained a trusted technology partner in supporting safe and efficient operations across our network.”
