3-1 Safety Input
This device incorporates eight safety inputs. Safety inputs are comprised of four (duplex) input
blocks.
● Input block 1: IN1 / IN2
● Input block 2: IN3 / IN4
● Input block 3: IN5 / IN6
● Input block 4: IN7 / IN8
The following diagnoses are carried out by setting input blocks:
Setting
With / without diagnosis (method)
2NC contact input
With diagnosis (The input devices connected to this device are diagnosed to
detect earth fault, short fault to +V, or cross short fault.)
PNP semiconductor input
Without diagnosis (The input devices themselves, connected to this device,
detect earth fault, short fault to +V, or cross short fault for their own outputs.)
1NO / 1NC contact input
With diagnosis (The input devices connected to this device are diagnosed to
detect earth fault, short fault to +V, or cross short fault.)
1NC contact input
Without diagnosis
Devices as shown below can be connected.
●
2NC, 1NO / 1NC, or 1NC contact output type switch
●

Light curtain
●
Laser scanner
●
Two-hand operation switch
●
Enable switch
●
Key selector switch
3-1-1 Contact Input Mismatch Allowable Time
If the safety input is 2NC or 1NO / 1NC, this device simultaneously monitors ON side of two
safety inputs of one system (“closed” status in the case of door switch). OFF side (“open” status
in the case of door switch) cannot be monitored.
