Product details

Module identity and I/O count

The 6ES7323-1BL00-0AA0 I/O module provides 16 digital inputs at 24 V DC (13-30 V signal, 7 mA) and 16 digital outputs rated 0.5 A per channel. Total output current is 2 A at 40 °C.

Key switching and isolation ratings

Input response times: 0 to 1 typically 100 µs, 1 to 0 typically 500 µs. Outputs switch resistive loads at up to 100 Hz. The module requires a 40-pin front connector and sits in the S7-300 rack. Isolation tested at 500 V DC.
