Buffalo Grove, IL

Carlo Gavazzi

released an addition to the Solitron family of solid-state relays.

RJ1P Series one-package microprocessor-controlled relays

(see PDF) have analog input and proportional output capabilities and are capable of switching single-phase 230, 480, or 600 V ac, up to 50 A ac loads with five operating modes, when controlled by 0-10 V dc or 4-20mA signals.

Carlo Gavazzi RJ1P Series one-package microprocessor-controlled relays have analog input and proportional output capabilities.

With an integrated heat sink, RJ1P is ready for DIN-rail mounting. The solid-state relay provides equipment designers the ability to precisely control output power. 4 mA or 0 V dc corresponds to 0% output, linearly increasing to 100% at 20 mA or 10 V dc.
A rotary selector switch on the front of the device is used to select the mode of operation– either phase angle, distributed full cycle, or three types of burst modes (1, 3, and 10 sec.) 
It works with analog output temperature controllers for switching applications, including heating and lighting and comes with an integrated varistor and extremely high surge capabilities (I2 = 18,000 A2s).
RJ1P is suitable for HVAC, lamp and lighting control, printing, plastic and rubber, wood, and industrial heating applications.
The Series carries the cRUus, CE and RoHS marks.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
