New Controls & Controllers Products

Process Control/Network withstands demanding applications.

NET ConcentratorÃ-® System provides 20-bit measurement resolution and data rates up to 100 megabits/sec. Using 10/100Base-T Ethernet or MODBUS RTU network, it connects legacy and distributed field devices to DCS, PLC, or PC-based strategy. DIN rail mount process control and distributed I/O network operates in peer-to-peer and peer-to-host configurations. Data logging capabilities allow up to...

Display Board helps control inventory and production.

Modular T-Card System consists of wall-mounted panels molded in plastic. Product inventory is color-coded to indicate normal, critical, and overstock levels. Production cycles begin when inventory drops below pre-determined levels. Columns can be assembled laterally without limitations and can be lengthened by adding extension sections. Key words are written on top portion of T-card and remain...

Digital ZVC Control is suited for capacitor switching.

Digital Zero Voltage Closing (ZVC) control mitigates transients associated with bringing capacitor banks online and eliminates damage and downtime resulting from voltage spikes. It automatically calibrates with Joslyn VBM switches and is continuously self-adjusting for temperature. Closing is synchronized with zero voltage in each phase, and 3 poles are closed independently. It works with Joslyn...

Boiler Control protects against thermal shock.

RTC Return Temperature Control monitors boiler return water temperature and operates 3-way diverting valve and boiler circulator to maintain minimum return temperature of 135Ã-

Understanding Water Hammer

In this eBook you will learn: What causes water hammer and why it is such a persistent problem. The role design plays in reducing the risk water hammer poses to your system. DFT's professional recommendations for coping with water hammer.

Capacitor-Free LDOs include reverse-current protection.

Series TPS731xx, TPS732xx, and TPS736xx linear regulators come in 5-pin, SOT-23 packages. Units do not require output capacitor for stability and consume less than 1 Ã-µA in shutdown mode. Characteristics include low-dropout voltage of 30 mV, low noise of 30 Ã-µVrms from 10 Hz to 100 kHz, and standard output voltages from 1.5-5 V. Products incorporate NMOS Topology and thermal-shutdown...

VAV Actuator provides open protocol control.

Predator-® VAV Actuator integrates LonMark-® certfied VAV controller in OpenAir direct-coupled damper actuator designed for 3-position floating control. Unit provides control of pressure-independent, single duct VAV/CV zone boxes. Preprogrammed control logic is configurable for variety of applications, including cooling or heating, fan, occupancy, and lighting control.

Manufacturing Systems permit plug and play assembly.

Re-configurable Manufacturing Systems (RMS) include integrated conveyor modules and manufacturing logistics software. Each section of system is stand-alone with its own controls and is connected to other modules via communication and power cable. RMS software offers ability to route pallets, and provides operator work instruction, inventory tracking, and connectivity to product, as well as line...

Controller tracks and sequences power supply.

Model LTC2923, in tiny 10-lead MSOP package, controls power-supply start up and shut down by introducing currents into feedback nodes. By properly selecting resistors, supply can be configured to ramp-up and ramp-down together, with options for fixed voltage offsets, time delays, or different ramp rates. Unit allows additional supply to be controlled with FET for systems that require tracking of...

Gauge measures battery capacity in handheld PCs.

Model LTC4150 bi-directional Coulomb counter monitors current through small sense resistor between battery and load or charger circuit. It indicates charge and discharge of battery through series of output pulses over single communication pin that can be counted by microcontroller. Supporting 1- or 2-cell LI-Ion and 3 to 6-cell NiCd or NiMH batteries, unit allows PDAs, cellular phones, and...

Read/Write Receptacles control peripheral devices.

Keytroller II, Slimtroller II, and Unitroller II use serial memory key and/or serial memory token, and connect with RS-232, RS-485, or USB interface. They allow designers to integrate capabilities such as access control/user authentication and data transfer or storage. Panel-mount devices work in PLC- or PC-controlled applications and withstand rugged environments where it would be inconvenient...
