In this post, we want to show how we used a RJ45 connector block for multi-point serial Modbus connections. Modbus RS-485 is often used in industry for data connections with industrial controls and instrumentation, such as VFD’s, flow meters, energy meters, etc. There are several ways of distributing the RS-485 wiring, and some OEM’s provide […]
We re-built a 200HP soft start for a customer. The customer had purchased a used soft start bucket to run a 200HP motor on a extruder press. The panel came with an older model Cutler Hammer soft start that worked for a short time, then it burned out. As you can see, the wiring was […]
Today we installed a digital amp meter display at a local animal feed processing facility. The customer has a motor driving a conveyor in a location not visible by eye. The motor is run with a standard contactor, so there is not a way to monitor the load on the motor. We placed a CT […]
This is a public service post, addressing an issue in newer versions of Outlook, and this has resolved it for us, so we want to share it. In newer versions of Outlook, clicking on a contact will open with a reduced view of the contact, showing only a few of the main details. To enable […]
We would like to show you a nice solution for an industrial potentiometer, AKA “Speed Pot”, to use for controls systems, especially for controlling the speed for Variable Frequency Drives. Typically, users would install a standard panel mount potentiometer, such as this one. This solution works fine, however, many potentiometers do not fit into standard […]
We are pleased to have provided troubleshooting and upgrade assistance to a local mfg. of roll formed sheet metal products. We received a call that their main roll forming machine was down, and needed attention immediately. We arrived at the plant and soon noticed that the PLC in the control cabinet was not communicating with […]
In the automation world, we have been getting more involved in the industrial networking side of things, specifically connecting PLC controlled machines to the office network. Traditionally industrial networking has been very expensive and cumbersome in order to get data from the office environment to the production machines on the plant floor. This data is […]
Today we finished a controls project for a paint line at a major semi-trailer mfg. The panels are simple, a 24vdc power supply, and a hand held pendant with UP/DOWN buttons to control hydraulic valve solenoids.
