8-通道数字量输入

This digital input module records binary signals from sensors operating in Zone 0+1 hazardous areas, permitting channel-by-channel short circuit and wire-break diagnostics. NAMUR sensors, optocouplers, mechanical contacts (LED diagnostics can be turned off via control byte) or other actuating elements can be connected via intrinsically safe devices.

The WAGO I/O System 750 XTR 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)
• Red LED (short circuit)
• Red flashing LED (wire-break)

Field and system levels are electrically isolated.

The device is ideal for operation in extreme environments thanks to:

• An extended temperature range
• Greater immunity to impulse voltages and electromagnetic interference
• Higher vibration and shock resistance
