Expandable programmable controllers

PLCs, DCSs & Controllers
T1s are the microprogrammable controllers in Toshiba's T-series family. They are fully fledged members of the T-series family and all programs written for a T1 will run on other T-series controllers. The T1s are palm-sized controllers with CPU, I/O and power supply all in one small block. Their small size makes them suitable for a variety of applications, including:
* Packaging machinery.
* Punch press control.
* Material handling.
* Washing and drying control.
* Pneumatic control.
* Conveyor control.
* Compliance monitoring.
The T1 series is available in three I/O configurations: 16 I/O (8 inputs/8 outputs), 28 I/O (14 inputs/14 outputs) and 40 I/O (24 inputs/16 outputs). The T1-40 can be expanded in three ways, increasing the I/O capability up to 328 I/O.
Option cards
Toshiba used its advanced surface-mount technology to develop an extremely compact I/O option card. The I/O option cards are approximately half the size of a credit card. Two option cards can be inserted into the PLC. The following cards are available:
* 16 point DC input.
* 16 point DC output.
* 8 DC in/8DC out combo.
* 1 channel analog input.
* 1 channel analog output.
* TOSLINE-F10 interface.
Option cards
Expansion racks
Connecting a 2-slot or 4-slot rack allowing it to utilise most T2 series I/O modules can further expand the T1-40. The following I/O modules are available for the T1-40:
* DC input, 24 V d.c, 16/32/64 points.
* AC input, 120/240 V a.c., 16 points.
* Relay output, 8/12/16 points.
* DC output, 24 V d.c., 16/32/64 points.
* AC output, 100-240 V a.c. 12 points.
* Analog input, 8/12 bit resolution/4-20 mA/1-5 V d.c./0-10 V d.c./-10 to +10 V d.c.
* Analog output, 8/12 bit resolution/4-20 mA/1-5 V d.c./0-10 V d.c./-10 to +10 V d.c.
* Position control, 5/12 V d.c.
* Communication interface.

Expansion unit
A block-type expansion unit is also available. Each expansion unit has 32 I/O points (16 inputs/16 outputs). The T1-40 can be connected to either one expansion rack or one expansion unit.
