Applications
- Digital signal acquisition: Acquires digital signals through 8 sourcing inputs with parameterizable input delay.
Key Features
- 8 digital inputs: Provides 8 parameterizable sourcing inputs with an IEC 61131 type 1 input characteristic.
- 24 V DC input and supply: Rated input and supply voltage is 24 V DC; the permissible supply range is 19.2 V to 28.8 V DC.
- Adjustable input delay: Standard-input delay is parameterizable from 0.05 ms to 20 ms, with an additional 30 to 500 μs delay depending on line length.
- Diagnostics and LEDs: Includes supply-voltage monitoring, diagnostic alarms, readable diagnostic information, a green PWR LED, green channel-status LEDs, and a green/red DIAG LED.
- BU type A0 connection: Uses BU type A0 for 1-wire and 2-wire connections; 3-wire connection requires BU type A0 with AUX terminals or a potential distributor module, while 4-wire connection requires BU type A0 plus a potential distributor module.
- Electrical isolation: Channels are isolated from the backplane bus; isolation is tested with 707 V DC in a type test.
