Type Function Symbol Description Reference page
Dual channel direct
opening input
Dual Channel
Direct Opening
This function is for connecting
safety devices with dual channel
direct opening action
mechanisms, such as
emergency stop switches or
interlock switches.
5-311
Dual channel
dependent input
Dual Channel
D epende nt
This function is for connecting
safety devices with dual channel
dependent action mechanisms,
such as enabling switches.
5-313
Dual channel
NO/NC input
Dual
Channel
NO /NC
This function is for connecting a
safety device with a dual channel
NO/NC mechanism, such as a
non-contact interlock switch.
5-315
Dual channel safety
input
Dual Channel Safety
This function is for connecting
safety devices with dual channel
solid state outputs (PNP output),
such as safety light curtains,
safety laser scanners, or safety
devices with dual channel
contacts, such as emergency
stop switches.
5-317
Mode select input
Mode Select
This function is for connecting
devices with a mode selector
function, such as a mode
selector switch.
5-319
Mode select input II
Mode Select
Ⅱ
This function is for connecting
devices with a mode selector
function, such as mode selector
switch. In case of switching if the
input is performed within 3s, the
function output is kept at the
previous state.
5-321
Muting input
Muting input
This function is for connecting a
sensor or any other input device
to perform muting.
5-323
Monitor input
Single Channel
Monitor
This function is for connecting a
switch or sensor for use as a
start input.
5-325
Input function
External device
monitor input
External Device
Monitor
EDM
This function is for monitoring
external devices controlled by
the SafetyOne. External devices
are diagnosed for errors by
connecting a NC contact, such
as a contactor or safety relay.
