Quaestiones Frequenter Rogatae

Can both outputs of 6ES7122-1BB00-0AA0 carry 0.5 A continuously at 60 °C?

No, the module total current is limited to 0.8 A at 60 °C.

How should I restore an output of 6ES7122-1BB00-0AA0 after clearing a short circuit?

Si reinitiatio sub onere pleno deficit, signum output muta, tensionem moduli oneris interrumpa, aut onus temporarie disconecte.

Num commutatio mechanica L+ impulsum brevem in output 6ES7122-1BB00-0AA0 producere potest?

Ita, output impulsum transitorium circa 8 µs ad currentem nominalem, aut usque ad 20 µs ad onus 10 mA, producere potest, cum L+ mechanice commutatur.

Num 6ES7122-1BB00-0AA0 lampam 5 W in uno output ducere potest?

Non, onus maximum lampae est 2.5 W.

Num duo outputs 6ES7122-1BB00-0AA0 ab omnibus SC isolati sunt?

Non, nulla isolatio galvanica inter outputs et omnibus SC est.

Quotiens 6ES7122-1BB00-0AA0 in suum blocum terminalium TB16SC inseri potest?

Numerus insertionum permittarum maximus est viginti.

Num outputs 6ES7122-1BB00-0AA0 parallele coniungi possunt ad controllem redundatem unius oneris?

No, outputs may not be paralleled for redundant load control.

Compatibility & Ordering Notes

Before ordering 6ES7122-1BB00-0AA0: Use the intended TB16SC slot and DC load supply, observe the module total-current derating and avoid unintended actuator response during mechanical L+ switching.

Compatibility Checklist for 6ES7122-1BB00-0AA0

• Keep each output within its permitted current range.
• Respect the 0.8 A module limit at +60 °C.
• Do not use parallel outputs for redundant control.
• Use the specified short-circuit recovery procedure if restart fails.
