Weidmullers High Density Digital Isolators
Weidmuller’s ACT20X range includes two types of digital modules – Pulse Isolators and Actuator Drivers. Pulse Isolators accept digital inputs from field equipment within a hazardous area. These include Namur and relay status and frequency signals from flow, pressure or level switches, and proximity sensors for position or motor speed measurements. These Pulse Isolators create isolated outputs for safe area controls. Each ACT20X module features an independent error alarm output for monitoring input signals and internal electronics. A dedicated, volt-free contact registers open/short circuits or internal errors for quick problem identification. The ACT20X range of digital isolators have Class 1, Div 2, Zone 0, and Zone 2 approvals with IECEx and ATEX certification, making them suitable for use in hazardous applications worldwide.
