General

A selection can be made between the following pieces of standard equipment depend-

ing on the task. Features in common and differences are summarized in Table 1.

1.4.1.1 STA 501, STA 551

The standard equipment of STA 501 and STA 551 can be used for A500 systems which

require many PMB slots. They differ from each other due to the primary voltage of the

power supply (24 VDC for the STA 501, 230 VAC with the STA 551).

1.4.1.2 STA 503, STA 553

The standard equipment of STA 501 and STA 551 is meant for A500 systems which re-

quire a low number of PMB slots. They differ from each other due to the primary volt-

age of the power supply (24 VDC with the STA 503, 230 VAC with the STA 553). The

STA 553 has 3 PEAB slots less than the STA 503 due to the wider power supply.

1.4.1.3 STA 557

The standard equipment of STA 557 can be used when B500 is to be employed. It con-

sists of the DTA 27.1 subrack with an unplugged PMB in order to accept A500 and

B500 modules. The position of the isolation point must be pregiven by the user when

he orders the device. 12 PMB slots can be segmented in 5 to 12 connected P500 slots

and correspondingly 0 to 7 A500 slots. The 13th PMB slot (on the right-hand side next

to the ALU) should preferably be used for a memory module.

1.4.1.4 STA 505, STA 555

The standard equipment of STA 505 and STA 555 can be used when B500 is to be

employed and differ from each other only due to the primary voltage of the power sup-

ply. They consist of the DTA 107 subrack with an unplugged PMB in order to accept

A500 and B500 modules. The position of the isolating point must be given by the user

when he orders the device. 11 PMB slots can be segmented in 5 to 11 connected B500

slots and correspondingly 0 to 6 A500 slots. The 12th PMB slot (on the right-hand side

next to the ALU) should preferably be used for a memory module.
