Overview
Eaton MTL isolated intrinsically safe power supplies power instrumentation in hazardous process areas, with IS output voltages from 4.8 to 17.7 V.
9493-PS models take a standard 24 V DC input and produce a 5.4 – 18 V nominal Ex ia output for devices in Zone 0 and Zone 1. Approvals and details vary by model.
Applications
- Powering MTL 9460-ET / 9470 IS Ethernet
- HMIs, tablets and instruments in Zone 1
