The trend towards increased monitoring in industrial automation and process control requires input modules with higher channel densities. In these applications, 24V DC digital inputs (DI) make up the ...

The following are some basic facts about input loop power sources: The input module usually isn't a loop power source. Although 120V is common for digital loops, other voltages are also used. There ...

I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...

The SNAP-IDC-32D digital input module, with 32 input points, can be used to sense on/off status for 2.5 to 12 VDC inputs from sources such as proximity switches, limit switches, push buttons, and ...

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 ...

Two new eight-channel, configurable Digital Input/Output (DIO) Modules have joined WAGO Corporation's IP67 SPEEDWAY 767 I/O-SYSTEM. Configurable channel-by-channel, the 767-5801 & 767-5802 modules ...

The 40-413 is a 32-channel digital I/O module with high-current outputs and dual threshold-voltage inputs. Typical applications include military, aerospace and automotive test systems. Three different ...

ifm electronic has introduced a range of Ethernet modules for field applications. The AL4xxx series decentralised digital input (DI) modules act as a link between binary sensors and the fieldbus, ...

This input module is part of the Modicon STB range, an offer of IP20 modular distributed I/Os on multiple networks and fieldbus. This basic digital input module offers 16 inputs with positive discrete ...
