Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...
Microcontroller-based systems with analog I/O can be simplified by modularizing them as stackable boards interconnected by a minimalist bus. The InterModule Bus (IMB) is a master-slave bus controlled ...
In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...
The MAQ20-BRDG1 strain gage module has four input channels and can interface to full, half, and quarter bridge sensors using four-wire or six-wire connections. All channels are individually ...
The BusWorks 965EN Input Modules interface thermocouple and millivolt signals directly to an Ethernet Modbus/TCP 10/100 network. The six-channel, inch-wide I/O modules operate independently of any bus ...
In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...
