Ebb (I/O Expansion Board B) - WEG CFW-09 User Manual

8.1.2 EBB
(Expansion I/O Board B)
Differential input for incremental encoder with isolated
internal 12 V power supply;
Buffered encoder output signals: isolated input signal
repeater, differential output, must use to external 5 V to
15 V power supply;
Analog input (AI3): 10 bits, isolated, unipolar, (0 to 10) V,
(0 to 20) mA/(4 to 20) mA, programmable;
2 Analog outputs (AO1'/AO2'): 11 bits (0.05 % of full
scale), unipolar, isolated (0 to 20) mA/(4 to 20) mA,
programmable;
Isolated RS-485 serial port;
Digital Input (DI7): isolated, programmable, 24 V;
Digital Input (DI8) for special motor thermistor function
(PTC): actuation 3.9 k, release 1.6 k;
2 isolated Open Collector transistor outputs (DO1/DO2):
24 V, 50 mA, programmable.
* Board with 5 V power supply for the encoder.
Switch
S2.1 AI4 – Speed reference
S3.1 RS-485 B-LINE (+)
S3.2 RS-485 A-LINE (-)
Obs.: Both S3.1 and S3.2 switches must be set for the same option (ON or OFF).
Note: For Size 1 models the CFI1 board (interface between the CC9 control board and the
HMI) must be removed to clear access to these switches.
Table 8.2 a) - EBA board selector switches configurations
NOTE!
The external signal and control wiring must be connected to XC4 (EBA),
following the same recommendations as for the wiring of the control board
CC9 (refer to item 3.2.6).
The EBB board can be supplied in different configurations, combining the
features included. The available configurations are shown in table 8.3.
Included Features
Table 8.3 – EBB board versions and included features
NOTE!
The use of the RS-485 serial interface does not allow the use of the standard
RS-232 input - they can not be used simultaneously.
The functions analogic outputs AO1' and AO2' are identical to the AO1/AO2
outputs of the control board CC9.
