|
|
Weight
|
Approximately 105 g without terminal unit
|
|
Mounting
|
Horizontal or vertical; natural convection must remain unobstructed
|
|
Central AC500 expansion
Install on a supported AC500 processor module through the S500 I/O bus. |
|
Decentralized I/O
Use with a compatible S500 communication interface module after checking the exact station configuration. |
|
High-density status acquisition
Collect up to 32 discrete 24 V DC field signals in one module. |
|
Pulse counting
Use I24 and I25 for a supported fast-counter application up to 50 kHz. |
|
Input terminals
I0 to I31 are assigned across the 40-terminal TU515 or TU516 terminal unit. |
|
Process supply
UP is +24 V DC and ZP is 0 V DC on terminal groups 1.8 to 4.8 and 1.9 to 4.9. |
|
I/O bus
Module logic is supplied internally through the S500 I/O bus. |
|
Data exchange
Four input bytes without fast counter; six input bytes and two output bytes with fast counter. |
|
Terminal unit
Mount DI524 on TU515 screw terminals or TU516 spring terminals. |
|
DIN rail
Use the terminal-unit installation drawing and maintain the specified cabinet clearances. |
|
Power isolation
Switch off supply and process voltages before connecting, removing or replacing the module unless all hot-swap conditions are satisfied. |
|
Cooling
Do not obstruct natural convection with cable ducts or adjacent cabinet parts. |
|
Electrical isolation
The digital inputs are isolated from the I/O bus at module level. |
|
Input protection
Official hardware data states reverse-polarity, reverse-supply, short-circuit and temporary overvoltage protection up to 30 V DC for I/O channels. |
|
Diagnostics
Channel-group and module LEDs indicate input state, process supply and module errors. |
|
Application limit
DI524 is not a safety module and is not intended for prohibited environments listed by ABB. |
