R. STAHL IS1 Relay Digital Output Module 9477/12-08-12 for Zone 1 Ex d e
Article No. 162627
Overview
The R. STAHL 9477/12-08-12 digital output relay module for Zone 1 offers 8 channels for solenoid valve operation not requiring intrinsic safety, with a high switching capacity. The outputs are available as potential-free relay contacts (make contacts) in Ex e or with Conduit connection technology. Combined operation with Ex i I/O modules is permitted.
- Up to 8 potential-free relay contacts
- Ex e outputs with high switching capacity up to 100 VA
- Zone 1 module can be hot-swapped
