The input/output modules plug into the I/O terminal unit. When properly seated, they are secured with two mechanical locks. All the connections are established via the terminal unit, which allows removal and replacement of the I/O modules without disturbing the wiring at the terminal unit.

TU516-01
1

I/O bus (10 pins, male) to connect the previous terminal unit, the CPU terminal base or the communication interface module to the terminal unit

2

I/O bus (10 pins, female) to connect other terminal units

3a

Plug (2 x 25 pins) to connect the inserted I/O modules

3b

Plug (2 x 19 pins) to connect the inserted I/O modules

XC version

XC = eXtreme Conditions

TU5xx-XC

Extreme conditions

Extreme conditions

Terminal units for use in extreme ambient conditions have no Snowflake, 1_4 sign for XC version.

The figure 4 in the Part no. 1SAP4... (lable) identifies the XC version.

These terminals are internally connected with assignment: process supply voltage UP = +24 V DC

These terminals are internally connected with assignment: process supply voltage ZP = 0 V

TU541, TU542 and TU542-H

These terminals are internally connected with assignment: process voltage UP = +24 V DC

Separate process supply voltage UP3 = +24 V DC

Separate process supply voltage UP4 = +24 V DC

These terminals are internally connected with assignment: process supply voltage ZP = 0 V

Separate process supply voltage ZP = 0 V

Separate process supply voltage ZP = 0 V

The assignment of the other terminals depends on the inserted communication interface module (see the description of the respective module used).

Check the given design scheme of your control cabinet.

Check the ‎⮫ terminal unit compatibility.
