Binary output 23BA40Connections and settings

Application, characteristics and technical data have to be takenfrom the hardware data sheet:

23BA40 Data sheet 1KGT 150 601

Operation

The 23BA40 has sixteen output relays. Each relay has its ownreturn. This allows to use individual process voltage levels for allchannels. See "Fig. X: Logic block diagram"Figure 6 for a blockdiagram of the 23BA40.

Processing function

The I/O micro controller (EAP Ein- Ausgabe-Prozessor / Input-output processor) activates any output forced by the communi-cation unit (CMU) by a command output request. The EAP con-trols the time duration of a pulse output by the loaded pulselength time value.

Output monitoring and supervision

Any output is checked and monitored by the EAP by differenttests and supervision functions:

• the output pattern is read back before the output is activat-ed

• the 24 V DC supply voltage to switch the output relays issupervised during an active output

• the pulse duration is controlled by the EAP• any detected error is indicated by LED’s

One or two pole outputs

Figure Fig. 7 to Figure Fig. 9 show the different principle wiringsfor one or two pole command output.

Settings

On the 23BA40, only the rack address and the device addresshave to be set via the DIL- switch S1. To access S1, the topcover has to be removed. Figure 1 shows the position, Figure

2, Table 7 and Table 8 show the layout of the DIL-switch S1.Furthermore a terminating resistor of 1kΩ for the serial peripheralbus can be activated via DIL-switch S1. See Table 9.

DANGER

Hazardous voltage.

Contact with live circuits will cause electric shock or burn.

Verify that all terminals feeding dangerous contact voltages(supply voltage, input or output channels) is in secure OFFstate before connecting or withdrawing the terminals.

ADVICE

• Never remove top cover when process voltage is ap-plied! Danger!

• DIL-switch S1 may only be operated under off-circuitconditions (24 V supply removed)

• Take ESD-protective measures before removing the cov-er

Signaling

The board monitors and checks its functionality as well as thedialog via the peripheral bus. Detected errors are indicated and/or transmitted by the board:

• by the red LED ”ST”• by the red LED ”PST”• by diagnostic messages

LED ”ST”

The „ST“ LED indicates board errors or peripheral bus errors.

The „ST“ LED indicates:

• board runs initialization procedure• board is doing a cold- or warm start• board has detected a memory error (RAM or EPROM)• micro controller faulty• no dialog via the peripheral bus for at least 2 minutes. The

board is not polled by the PBP of CMU.

LED ”PST”

The LED indicates an error at command output:

• 24 V DC for the output relays failed during command output• Time-out PBP during active output. Any active output is

stopped (switched off).

LED ”1...16”

The LED’s are dedicated to the output relays. The LED’s are ONthe time an output is active (pulse or persistent).

LED ”5V”

The LED indicates that the 5 V DC power is applied.

Several devices 23BA40 and 23BE40 can be mounted side byside on an EN-rail. The connectors X3, X4 and X5, X6 are suitablefor through-wiring. The internal wiring is designed for up to 8devices 23BA40 or 23BE40.

The Event-line (E) connects all devices of one string (up to 8). Nofurther connection to other devices is allowed. The cable shieldshall be grounded near the devices.

From the software point-of-view the module 23BA40 is treatedas a 23BA20 mounted in a dedicated rack on a dedicated slot(device address). This virtual rack has 8 different devices.

One power supply unit 560PSU40 is able to drive up to 8 mod-ules 23BA40.

The following configuration and wiring rules apply to 23BA40 and23BE40 as well:

• Not more than 8 modules per 560PSU40• Not more than 8 modules per rack• All modules with connected E-line must have the same rack

address• The E-line must be wired between 23BE40 and 23BA40

modules with same rack address, but need not to be con-nected to any other device

• Terminate only the last module within a bus segment
