【英文介绍】
The Guard I/O DeviceNet security module with directory number 1791DS-IB8XOB8 is a security output module with a solid state output. The module has embedded I/O modules, such as eight (8) security inputs, eight (8) solid state outputs, and four (4) test outputs.
The 1791DC-IB8XOB8 module is equipped with a housing of Protection Class (IP) 20. 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 EN 954-1.
The safety input is designed for filling wiring configurations with a minimum on-state voltage of 11VDC and input current of 6 mA. The test output channel supports source configurations with rated output current of 0.7A, maximum residual voltage of 1.2V, and maximum leakage current of 0.1mA. The safety output also supports power wiring, and the rated output current is 0.5A, the maximum residual voltage is 1.2V, and the maximum leakage current is 0.1 mA.
The 1791DC-IB8XOB8 has built-in self-diagnostics and configuration locking. The module's integrated I/O status data provides information about single point input state, combined input state, single point output state, combined output state, single test output state, and single output read-back (the actual on/off state of the output).
Allen-Bradley 1791DS-IB8XOB8 CompactBlock is a DeviceNet protection module. It has 20.4 to 26.4 volts DC I/O supply voltage (nominal voltage is 24 volts DC), 11 to 25 volts DC communication supply voltage, and 110 mA current consumption (24 volts DC).
The module has 8 safety inputs, 4 test outputs and 8 solid state safety outputs, and is equipped with a separate status indicator. The input of the module is a current-absorbing input type with an input current of 6 amps and a maximum turn-off current of 1 mA. The minimum input voltage for the on-state of the 1791DS-IB8XOB8 is 11 volts DC. The 1791DS-IB8XOB8 has a maximum turn-off input voltage of 5 volts DC. The module's current source test output has a maximum leakage current of 0.1 mA, a rated output current of 0.7 Amps, and a maximum residual voltage tage of 1.2 V. On the other hand, the current source safety output of the 1791DS-IB8XOB8 module has the same maximum leakage current of 0.1 mA, the same residual voltage (maximum 1.2 volts), and a rated output current of 0.5 amps.
