To discharge EMC interferences, connect the FE connection (12) to the I/O module via a
low-impedance line to functional earth. The cable cross-section must be selected according to
the application.
The combination module has two connections for connecting E/P pressure regulators. These are
designed as M12 sockets, female, 5-pin, A-coded.
The connection ID for
input channel 1/output channel 1 is X2A1,
input channel 2/output channel 2 is X2A2.
See Table 11 for the pin assignments of the connections X2A1 to X2A2.
Table 11: Pin assignments of the connections
Pin Sockets X2A1 to X2A2
Pin 1 24 V DC for the E/P pressure regulator
Pin 2 Output signal (set point for the E/P pressure regulator)
Pin 3 0 V DC for the E/P pressure regulator
Pin 4 Input signal (actual value from the E/P pressure regulator)
Pin 5 Shield, connected internally with ground screw (12)
The cables from the device to connections X2A1 and X2A2 must be shielded. The shield must be
connected to pin 5.
The cable length must not exceed 30 m. The average load current must not exceed 1.2 A per supply
output.
Maximum input voltage on the signal inputs:
Voltage measurement range: ±12 V
Current measurement range: ±5 V
NOTICE! The channel type (input channel and output channel) can be set in the parameter data (see
"6.3 Parameter data and data formats for the process data" on page 88).

LEDs

The I/O modules have only module-related LEDs and no channel-related LEDs. The module-related
LEDs (1), (2), and (3). are for voltage and diagnosis monitoring.
The channel-related LEDs (9) are not present with analog modules; however, the semi-circular
optical conductors are visible due to the design.
Table 12 describes the functions of the LEDs. For a comprehensive description of the LEDs, see "8
LED Diagnosis on the I/O Modules" on page 115.
