PLCs, Power Supplies & Others

The ASB817116 from Schneider Electric functions as a dedicated isolated input module within the Modicon Premium automation platform. This unit provides reliable signal acquisition for discrete sensors and switches operating on 115 VAC control power. Its 16-point isolated design ensures each input channel maintains complete electrical separation from the others. Therefore, ground loop issues or voltage spikes affecting one channel cannot compromise the remaining 15 inputs.

Weighing approximately 0.66 lbs (0.30 kg), the ASB817116 features a robust housing suitable for standard Premium rack mounting configurations. The module draws its operational power directly from the backplane while accepting 115 VAC field inputs at either 50 or 60 Hz frequencies. This frequency flexibility makes the unit suitable for international installations where power mains specifications vary by region. Additionally, the module operates reliably across temperatures from 0°C to 60°C, ensuring consistent performance in industrial environments.

Comprehensive Input Isolation and Diagnostics

Each of the 16 input points on the ASB817116 incorporates opto-isolation technology to protect the backplane and processor from high-voltage transients. The module accepts field wiring through a removable terminal block, simplifying installation and future replacement without disturbing existing connections. Built-in LED indicators provide immediate visual confirmation of each input’s status, displaying ON or OFF states at a glance. These diagnostic features enable maintenance personnel to quickly identify wiring faults or sensor failures during routine troubleshooting.
