R. STAHL Remote I/O IS1+ Digital Output Module for Zone 1 Ex i
Art. No. 9475/32-04-12
Product Overview
The R. STAHL 9475/32-04 digital output modules for Zone 1 are designed for controlling Ex i solenoid valves or indicator lamps. They feature four channels for Ex i solenoid valves up to 40 mA and an additional Ex i control input for safe shutdown up to SIL 2. All outputs are short-circuit proof, galvanically separated from the system, and individually monitored for wire breakage/short-circuiting.
Key features include:
- 4 channels for Ex i solenoid valves up to 40 mA
- Ex nA outputs with line fault monitoring, LED fault and status display for each channel, and SIL 2 shutdown input
- Modules in Zone 1 can be replaced without disconnecting the power supply (hot-swapped)
