ABB AC500 PLC - Functionality; Electrical Connection

Functionality
2 analog outputs, individually configurable for
● Not used (default setting)
● -10 V...+10 V
● 0 mA...20 mA
● 4 mA...20 mA
Parameter Value
Resolution of the analog channels
Voltage bipolar (-10 V...+10 V) 11 bits plus sign
Current (0 mA...20 mA; 4 mA...20 mA) 12 bits
LED displays 2 LEDs for process voltage and error messages
Internal supply Via I/O bus
External supply Via the terminals L+ (process voltage 24 VDC)
and M (0 VDC); the M terminal is connected to
the M terminal of the CPU via the I/O bus
Electrical Connection
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly chapter Ä Chapter 2.5
“AC500-eCo” on page 1192.
If the output is configured as not used, the voltage and current output signals
are undefined and must not be connected.
The electrical connection is carried out by using a removable 11-pin terminal block. These ter-
minal blocks differ in their connection system (spring terminals or screw-type terminals, cable
mounting from the front or from the side) Ä Chapter 1.8.3.2 “TA563-TA565 - Terminal Blocks”
on page 1164. The terminal blocks are not included in the module's scope of delivery and must
be ordered separately.
The following block diagram shows the internal construction of the analog outputs:
