AC motor speed controllers

This series of compact AC motor speed controllers features two models that can control AC motors and gearmotors with speeds ranging from 90 rpm to 1,400 rpm (50 Hz) and 90 rpm to 1,600 rpm (60 Hz). The ES01 has an input power of 110/115V and the ES02 has an input power of 200/230V. The controllers can be used with the company's World K and V series AC induction or reversible speed control motors, which have power output ranges of 6W to 60W and 6W to 90W, respectively.

Programmable logic controllers

Modicon Momentum PLCs are now available with conformal coating, which allows them to withstand corrosive and high humidity environments, and acts as a barrier against moisture, fungus, dust, and other environments, especially those particular to the water/wastewater, oil, and gas industries. The controller has a small footprint, which makes it suitable for small to mid-range applications.

Controller/data acquisition unit

Designed to work with programmable logic controllers, intelligent I/O devices, and other supervisory control and monitoring systems, the Mini8 can function as a high-stability 4-loop or 8-loop PID controller unit or a 32-input data acquisition unit. It features four plug-in I/O slots and can be used with HMI software, a PLC, or a standalone unit.

Ethernet controller

The 750-841 series Ethernet TCP/IP programmable fieldbus controller now features 256 kB of data memory, a multi-tasking operating system, and the ability to complete online programming changes. The controller has a 32-bit RISC processor, 512-kB program memory, 24-kB retentive memory, 100 Mbps Ethernet, IEC-61131-3 programming, and open architecture software interfaces and protocols. It's compatible with all 750 series I/O modules.

Solid-state relay assemblies

Rated for loads as high as 100A at 40° ambient temperature, the assemblies consist of solid-state relays that are attached to anodized aluminum heat sinks. Available in 24VDC to 280VDC, 48VAC to 530VAC, and 48VDC to 530VDC, each unit features a DIP switch, which allows for control input of 1 ohm to 135 ohms, 4mA to 20mA, 0V to 5V, 0V to 10V, or input from potentiometer command signals. The assemblies come with finger-safe covers, DIN rail mounts, and integral LED status indications, as well as transient overvoltage protection at either 600Vpk or 1,200Vpk.
