ABB DI572 16-Channel High-Voltage AC Digital Input Module
A 16-channel high-voltage AC input module arranged as two isolated groups for direct 100–240 V AC field-signal acquisition.
Product Profile
ABB DI572, article 1SAP230500R0000, provides 16 digital inputs for 100–240 V AC signals. The channels are divided into two groups of eight, allowing a compact S500-eCo station to acquire high-voltage discrete states while maintaining isolation from the module logic.

System Role
- Acquires high-voltage AC status signals for a centralized or supported decentralized AC500 I/O station.
- Maps the 16 input states into two bytes of controller process data.
- Separates each eight-channel field group from the remaining module circuitry.
- Provides one yellow status LED per input for local commissioning and diagnosis.
- Connects through the S500-eCo I/O bus while field signals use removable terminal blocks.
Compatibility
- Can be used as a centralized extension under supported AC500 CPUs.
- ABB also documents use with supported S500 communication interfaces including CI592-CS31, CI501-PNIO, CI541-DP and CI581-CN.
- ABB excludes use as a decentralized module with CI590-CS31-HA.
- One 9-pin and one 11-pin S500-eCo terminal block are required and ordered separately.
- Hot swap is not supported; all relevant voltage sources must be removed before service work.
Applications
- Monitoring contactor, breaker or auxiliary states operating at 100–240 V AC.
- Machine and process panels with sixteen high-voltage discrete signals.
- Remote I/O stations using a compatible ABB communication interface.
- Brownfield installations that require two isolated eight-channel AC input groups.
- Active spare planning for DI572 article 1SAP230500R0000.
FAQ
What signal voltage does DI572 accept?
It is designed for 100–240 V AC digital inputs and permits a documented 0–264 V AC range at 47–63 Hz.
How are the 16 channels divided?
They are arranged as two groups of eight channels.
What voltage is recognized as signal 1?
The official technical data specifies 79 V AC as the minimum signal-1 level.
Can DI572 be used with CI590-CS31-HA?
No. ABB explicitly excludes decentralized use with CI590-CS31-HA.
Which terminal blocks are needed?
The module requires one 9-pin and one 11-pin S500-eCo terminal block, ordered separately.
Is DI572 a safety input module?
No. DI572 is a standard digital input module; ABB safety inputs use separate safety-specific products.
