An MSR320 Input Module can be set up for any one of the following safety functions:
• Logic function (Group3 = Input1 OR Input2 OR Group1)
• 1-channel emergency stop
• 2- channel emergency stop or 4-wire safety mat
• 3- channel emergency stop
• Safety gate (N/O, N/C) with start-up test
• Safety gate (N/O, N/C) without start-up test
• Light curtains: both inputs
• Two-hand
operation
• Input 1 = 2-channel emergency stop; Input 2 = Light curtain
• Input 1 = Safety gate without start up test; Input 2 = Light curtain
The terminal of third channel of an Input Module acts as an auxiliary output (+24
VDCsignal if input active) when the Input Module is configured for 1- or 2-channel
monitoring. The same terminal acts as the third input when an Input Module is configured
for 3-channel monitoring.
