5.3 RS485 serial interface

The RS485 serial card option (IROPZ48500), shown in Figure 5.l, allows the ir33 instrument to be connected to the RS485 serial

network for supervision. In addition, the serial interface option IROPZ485S0 is available, with automatic recognition of the polarity

(+ and -).

For further details, refer to the corresponding instruction sheet.

5.4 Programming kit

This accessory interfaces the IROPZKEY00 programming key with any PC; this useful tool can be used to program the key using the

standard instrument parameters, and save the di erent con gurations to  les that can be recalled during  nal programming.

The user can change the password, hide the parameters, change the level of visibility (with password protection or direct access)

and, most importantly, assign the output relays according to the con guration of the utilities.

5.5 Transformers (ir33, power, DIN)

The transformers are used to convert mains voltage to the power supply voltage speci ed for the ir33 and ir33DIN series control-

lers. Their compactness and sound design (winding immersed in plastic) mean they can be used in all types of applications.

Code: TRA12VDE00: Transformer, 3VA 240/12VAC VDE - 153/M

5.6 RS485 serial board (DIN)

The IROPZSER30 board is used to connect the ir33DIN via the RS485 network serial to the PlantVisor supervisory system (using the

removable terminal supplied), as well as direct connection of the instrument to the repeater display using a PSTCON**B00 cable.

5.7 RS485 serial board (MasterCella)

The IROPZSEM10/30 boards are used to connect the mastercella via the RS485 network serial to the PlantVisor supervisory sy-

stem. The IROPZSEM30 board also allows the repeater display to be connected directly to mastercella using a PSTCON**B00 cable.

Codes:

• IROPZSEM10: RS485 serial board;

• IROPZSEM30: RS485 serial board + repeater display connection.

5.8 Door interlock (MasterCella)

Mastercella can be installed with a door interlock disconnecting switch, rated to 32 A, for the complete on/off management of all

the units; this device allows the system to be locked in the “Off” position so that service operations can be performed in complete

safety.

Codes:

• 0402512CEL, 32 A disconnecting switch;

• 0402515CEL, shaft H=85mm;

• 0402517CEL, switch with yellow/red indicator.
