Figure 29 - Dual-load Bipolar Outputs (1732ES-IB12XOBV2 or 1732ES-IB8XOBV4)
This example shows wiring and configuration when using the Guard I/O
module with solid-state outputs in Dual-channel mode.
All safety outputs of this Guard I/O module are permanently configured for
use as Dual-channel mode only. When used in combination with the programs
of the safety controller, this circuit configuration is Safety Category 4 in
accordance with ISO 13849-1:2008 wiring requirements and is rated up to
Performance Level e.
IMPORTANT For the bipolar safety outputs to work as intended, you must connect the
devices that are being controlled as shown in this figure. Connection of
devices directly to 24V DC, 0V DC, or ground is strictly prohibited.
