Dimensions and Mechanical Data

The 1P 243 is a printed circuit board in double European format, with dimensions of 233.4 mm x
160 mm (DIN 41494). In accordance with the SIMATIC S5 compact peripheral system, the PCB
takes up one slot in the rack. It has a width of 1–1/3 SPS1 (20 mm). 42 Faston connector pins (2.4
mm x 0.8 mm) are located on the front plate. The bus connection is made via a second row,
48–way base connector. The base connector is located on the upper half. Ground (Mext) connec-
tion is provided via contact strips in the guide rails.
Overview of the Individual Variants
The 1P 243 is available in one full–configuration version and two different part-configuration ver-
sions. The full–configuration module has the following independent functions:
– 1 Analog/digital converter, 8 channels, 12 bits, 35 psec. conversion time,
bipolar or unipolar
– 2 Digital/analog converters, 12 bits, bipolar
– 1 Digital/analog converter, 8 bits, unipolar
– 1 Analog output amplifier
– 4 Analog value conditioning circuits with operating point and amplifier setting
– 2 Difference amplifiers (P controllers) with adjustable gain
– 2 comparators with gating logic connected in series, can be read in statically and/orwith inter-
rupt generation (interrupt evaluation is only possible for the SIMATIC S5–150U/S and
– 8 binary inputs can be read in statically and/orwith interrupt generation (interrupt evaluation is
only possible for the SIMATIC S5– 150U/S and S5–155U with externally–wired digital input
module for interrupt generation).
– 8 binary outputs, 24 V, 200 mA, switching to P potential, not current–limited.
The inputs and outputs of the analog function groups are routed to the analog signal jumper
block. This makes it possible to combine the individual functions to suit user requirements. All
signals are nonfloating.
