FPΣ (Sigma) S-Link Expansion Unit
Flexible wire-saving link system S-Link
S-LINK unit
Features
࡯ Up to four S-Link units can be attached to one FPΣ (Sigma) CPU.
࡯ Each unit supports up to 128 I/O signals over a pair of wires up to a distance of 200m
(400m when a booster is used).
࡯ The combination of input and output point quantities (a total of 128 points max.) can be set by
the rotary switch in increments of 32 points.
࡯ The transmission line connection is realized via a T-branch multi-drop wiring with hook-up
connectors. Adding devices is rendered easy and maintenance is easy.
FPΣ (Sigma) + S-Link unit
FPG-SL
Features
࡯ The four-wire cable (two signal wires and two power
wires) enables efficient wiring, and the T-branch wirinig
enables a flexible connection layout.
࡯ About 60 types of S-Link input/output devices can be
connected to this unit, enabling it to meet diverse I/O
needs. In addition, the high transmission voltage
(24VDC) and the wide clock width (35µs) provide high
noise immunity. Flexible and reliable wiring is available,
reducing the wiring work.
Features
࡯ The control unit automatically recognizes I/O allocation in accordance with the attached S-Link unit
position, making the S-Link unit as easy to use as a common expansion I/O device.
࡯ If the main wire is broken and an input/output device cannot be recognized, then the S-Link unit displays
the device number. This function significantly reduces the time required for troubleshooting during an
equipment startup check or recovering from on-site problems.
