Description
This digital input module records binary signals from sensors operating in Zone 0+1 hazardous areas.NAMUR sensors, optocouplers, mechanical contacts or other actuating elements can also be connected via intrinsically safe devices.The WAGO I/O System 750/753 must be installed either in Zone 2 or in a non-hazardous area. Each sensor is supplied with a short-circuit-protected voltage of 8.2 V.Indicators:Green LED (signal on)Field and system levels are electrically isolated.
Specification
Notes
| Note | The digital input module must only be operated with a 24 VDC Ex i power supply!General information on explosion protection, including installation regulations, can be found in the WAGO I/O System 750/753 manuals! |
