1. General Introduction
The module includes Intrinsic Safety protection components on each channel for connection to process equipment in hazardous areas without the need for additional external devices.
Each channel can drive a nominal current of 40 mA into a 300 ohm field load such as an Ex certified solenoid valve, alarm sounded unit or indicator lamp. Open and short circuit detection can be configured for each channel. All four channels are galvanic isolated between channels and from the Module Bus and power supply. Power to the output stages is converted from the 24 V on the power supply connections.
TU890 and TU891 Compact MTU can be used with this module and it enables two wire connections to the process devices without additional terminals. TU890 for Ex applications and TU891 for non Ex applications.
