1791DS-IB8XOB8 Guard I/O Devicenet Safety module
The Guard I/O DeviceNet Safety Module with catalog number 1791DS-IB8XOB8 is a safety output module with
solid state outputs. This module has embedded I/O modules such as Eight (8) Safety Input, Eight (8) Solid State outputs and Four (4) Test Outputs.
The 1791DC-IB8XOB8 module comes with an enclosure with Ingress Protection (IP) 20 rating. It can be
used in applications that require Safety Integrity Level (SIL) 3. It complies with the IEC 61508 standard, and Safety Category 4 as specified in the EN 954-1.
The safety inputs are designed for Sink wiring configuration with minimum On state voltage of 11VDC and input
current of 6 mA. The Test output channels support sourcing configuration with rated output current of 0.7A with
maximum residual voltage of 1.2V and maximum leakage current of 0.1 mA. The Safety outputs supports sourcing
wiring as well, with rated output current of 0.5A, maximum residual voltage of 1.2V and maximum leakage current of 0.1 mA.
1791DS-IB8XOB8
The 1791DC-IB8XOB8 has built-in Self-diagnostic functions and configuration lock feature. The module’s
integrated I/O status data provide information regarding Individual Point Input Status, Combined Input Status, Individual
Point Output Status, Combined Output Status, Individual Test Output Status, and Individual Output Readback (actual ON/OFF state of the outputs).
The Allen-Bradley 1791DS-IB8XOB8 CompactBlock is a DeviceNet guard combination module with a 20.4 to 26.4
Volts DC I/O power supply voltage (with a nominal voltage of 24 Volts DC), an 11 to 25 Volts DC communications power supply voltage and a 110-mA current consumption of at 24 Volts DC.
