Chapter 5 Safety Module Features
• Solid-state outputs
• Single-channel mode uses one output signal, that is, data from an output
channel, to provide control.
• Dual-channel mode uses two output signals, that is, data from two
output channels to provide redundant control.
• Safety outputs can be pulse-tested to detect field wiring short-circuits to
24V DC.
Safety Output with Test Pulse
When the safety output is on, the safety output can be configured to pulse test
the safety output channel. By using this function, you can continuously test the
ability of the safety output to remove power from the output terminals of the
module.
IMPORTANT Single-channel mode is only certified for functional safety
applications with process safety times greater than or equal to
200 ms; or, applications with demand rates less than or equal to 3
demand per minute.
