Logical AND Function Adds Flexibility
to I/O Expansion

• Facilitates partial or complete control system setup.

• Solid-state outputs (excluding Expansion Units).

• Detailed LED indications enable easy diagnosis.

• TÜV Product Service certification for compliance
with IEC/EN61508 (SIL3) and EN954-1 (Cat. 4).

• Approved by UL and CSA.

• New unit joins the Series with the following
two additional features:

-OFF-delay time of up to 150 seconds
(The OFF-delay output also complies with Cat. 4.)

-Two logical AND connection inputs

● Productivity

“Partial stop” and “Complete stop” enhance productivity without sacrificing safety.

● Maintenance

LED indicators and detachable terminals for better maintenance.

● Expandability

“Logical connection” enables easier modification and expansion of machines.

Ex) Machining Center

• When the Emergency Stop Switch is pressed, the entire machine will stop.

• When a door is open, the corresponding part will not activate.

Response Time and Operating Time

The following table shows the response time for two or more Units that are logical AND connected.

Note: 1. The maximum response time (not including Expansion Units) in this block flow diagram is the time it takes the output from the Unit on the

lowest tier to switch from ON to OFF after the input to the Unit on the highest tier switches from ON to OFF.

2. The maximum response time (including Expansion Units) in this block flow diagram is the time it takes the output from the Expansion Unit
connected to the Unit on the lowest tier to switch from ON to OFF after the input to the Unit on the highest tier switches from ON to OFF.

3. The maximum operating time (not including Expansion Units) in this block flow diagram is the time it takes the output from the Unit on
the lowest tier to switch from OFF to ON after the input to the Unit on the highest tier switches from OFF to ON.

4. The maximum operating time (including Expansion Units) in this block flow diagram is the time it takes the output from the Expansion
Unit connected to the Unit on the lowest tier to switch from OFF to ON after the input to the Unit on the highest tier switches from OFF to
ON.
