By definition, digital inputs are either on or off. Thus, verifying the absence or presence of voltage is a critical part of troubleshooting digital input modules.

Digital input serializers (DIS), the heart of digital input modules, must operate in harsh industrial environments. Voltage and current transients caused by electrostatic discharge, switching of ...

Pickering Interfaces, a provider of modular signal switching and simulation products for electronic test and verification, has announced four new industrial digital I/O families for PXI- and LXI-based ...

In this design the industrial digital-input serializer (U1) translates, conditions, and serializes the 24V digital output of sensors and switches to CMOS-compatible signals required by ...

These high-channel-count output modules expand the existing 40-412 PXI range of digital input/output modules, adding a PXIe option (model 42-412A).

The I/O modules allow easy connections for photo eyes, proximity sensors, limit switches, pushbuttons, light curtains, or any other discrete control device. The 12-bit, low-resolution, 4-channel, ...

Digital input module options include Balanced XLR (AES/EBU).Optical/Coaxial (S/Pdif), MSB USB or ProUSB, MSB ProISL Interface, MSB Dual ProI2S Input, MSB Network Renderer V2 (MQA and Roon Ready).

Unlike traditional failsafe analog input modules, this module does not require redundancy to achieve SIL 3 certification. Hart communications and diagnostics for the module are set up from a central ...

ACCES I/O Products has announced its newest Ethernet-based data acquisition computer solution – the eNET-AIO16-16F. This standalone, high-speed analogue input/output module delivers reliable, flexible ...

Troubleshooting PLC Digital Input Modules, Part 2 If input power is missing, the causes can be such things as blown fuses, broken wiring, or broken connections.
