TXM1.6R Siemens OUTPUT MODULE

• Two fully compatible versions:

– TXM1.6R: – 6 volt-free relay outputs

– Individual I/O point signaling with green I/O status LED

– TXM1.6R-M: As TXM1.6R, but with the following additional features

– Three-color I/O status LED (red, yellow or green)

– Local override (to ISO 16 484-2)

• 6 relay outputs, which can be individually configured as:

– Maintained contact or pulse, 1 … 3-stage

– Three-position control output with stroke algorithm

• Mixed voltages (AC 250 V mains voltage and SELV/PELV 24 V) as well as

mixed phases are permitted on adjacent I/O points of the module

• Compact DIN format, small footprint

• Separate terminal base and plug-in I/O module for convenient handling

– Self-establishing bus connection for maximum ease of installation

– Terminal isolation function for fast commissioning

– I/O module replaceable in seconds, without rewiring and without affecting

the full functioning of the remaining I/O modules

• Terminal strips are required to connect N and PE of the field devices

• Simple strategy for operation and display

– I/O status LED for each I/O point

– LEDs for fast diagnostics

• Double-sided labels for identification of all I/O points
