Technical Description

1.1 Application

In SIMATIC S5-115 U, S5-135 U, or S5-155U programmable logic controllers and extension
units, the IP IP 244 B temperature control module can be used as an intelligent I/O module for
closed-loop control tasks in machine controllers. An additional adapter casing (order no. 6ES5
491-0LA11) is required for installing the module in an AG 115 U PLC. In S5 systems, the mo-
dule is used for temperature control and for measuring analog sensor signals. The manipulated
variable is output as a digital value. Temperature control at plastic injection moulding machines
and monitoring injection pressure and closing force are special applications of this module.
The module offers the following features:
either: – 15 analog input channel for direct sensor connection
Channels 0...12 have been prepared for thermocouple connection
when the module is delivered.
Channels 13 and 14 are used for measuring sensor signals
Channel 15 is used as compensation channel for thermocouples and is suit-
able for direct connection of a Pt100 resistance thermometer.
or: – 8 analog input channels for direct connection of 4-wire resistance
thermometers (0...512 mV)
– 17 digital output channels for outputting the manipulated variable of the closed-loop control-
ler (pulse width modulation). Actuators can directly be connected (120 mA nominal output
current).
– Autonomous closed-loop controller for up to 13 control loops.
– The closed-loop control function is independent of the mode of the PLC CLU.

1.2 Structure

The IP 244 B temperature control module is a compact module in double-height Europa format
in ES 902 packaging system with 48-way backplane connector. The backplane connector forms
the interface to the SIMATIC S5 bus.
The analog input signals connect to a 37-way male connector type "D" (X3), and the digital I/O
signals connect to a 37-way female connector (X4). Both connectors are located on the front
panel. Two connecting cables (one end with a matching connector, the other end loose) are
available (see Chapter 4, "Spare Parts").
L+ (24-V load voltage) is connected to a push-on blade connector on the front panel. L– is con-
nected to the reference potential of the controller (central grounding point in the cabinet). The
module is grounded via the M
19 green LEDs on the front panel indicate the operating states of the temperature controller mo-
dule, the input, and the outputs.
