Features
- Switch-selectable inputs 0/4 ... 20 mA and 0/2 ... 10 V intrinsically safe ATEX II (1) G [Ex ia] IIC ATEX II (1) D [Ex iaD]
- Switch-selectable outputs 0/4 ... 20 mA simultaneous 0/2 ... 10 V
- Supply voltage 85 ... 253 V AC or 10 ... 30 V AC/DC
- Full 3-port isolation
- Integrated transmitter supply for active 2- and 3-wire sensors (ST500-Ex only)
- Power-on LED
- 22.5 mm case for DIN rail mounting
The isolating signal converter can be used to isolate industry standard signals 0/4 ... 20 mA or 0/2 ... 10 V DC out of the Ex area. The universal design of the in- and outputs and the wide range of supply voltage limits the devices into 2 models. The ST500Ex provides an isolated transmitter supply for direct connection of active 2- wire sensors (4 ... 20 mA) and 3-wire sensors in the Ex-area.
