Switch & Distribute Signals
Isolate field devices, add fuses and manual switching, and distribute power in the panel.
Relay Terminals & Terminal Blocks →Connect PLCs & Servos
Replace point-to-point wiring with connector cables and interface terminals.
Interface & Push-In Terminals →Replace Legacy Equipment
Migrate discontinued PLCs and remote I/O without rewiring the field side.
PLC Adapters & Remote I/O →Network Field I/O
Collect I/O over CUnet, CC-Link, PROFIBUS or conductor rails on moving carriers.
Remote I/O & Toline →Compact & Robust Multiplexing
Toline XM Series
Toline XM multiplexes PLC I/O over two conductor rails, so carriers keep communicating while they move. One TBM32 master reads the PLC’s internal I/O registers over Ethernet and controls up to 32 carriers at once. Signals run at 48 VDC, which keeps communication stable across sliding collectors and helps clear oxide film from the rails.
Running an earlier Toline generation? We support upgrades to Toline XM and to TOLINE-V remote I/O (TKN-V).
Simultaneous Signalling
TBM32 (Master)
TBM32 also transmits signals to all slave units simultaneously.
TBS32 (Slave)
TBS32 (Slave) communicates with TBM32 via conductor rail. Slave modules can handle up to 224 points of I/O, using a combination of XD216 and TYN16 I/O modules. This system does not require a PLC or I/O on the carrier, reducing costs.
TSE32 (Slave Ethernet I/F)
TSE32 (Slave Ethernet I/F) interfaces between TBM and the carrier PLC.
