The Siemens 6ES7321-1BH02-0AA0 SIMATIC S7-300 Digital Input SM 321 is an optically isolated digital input module designed for use in SIMATIC S7-300 programmable logic controllers. Here are the key specifications and features of this module:
Number of Digital Inputs: It provides 16 digital inputs (DI).
Supply Voltage: The module operates at a supply voltage of 24 V DC. The permissible range for the load voltage is between 20.4 V and 28.8 V DC.
Input Voltage: The rated input voltage for signal "0" is 24 V DC, and for signal "1", it ranges from -30 to +5 V DC.
Input Current: The maximum input current from the backplane bus is 10 mA, and for signal "1", it is typically 7 mA.
Input Delay: The input delay is parameterizable, with a minimum of 1.2 ms and a maximum of 4.8 ms for transitioning from "0" to "1".
Cable Length: The maximum cable length for shielded cables is 1000 m, and for unshielded cables, it is 600 m.
Encoder Connectivity: It supports 2-wire sensor connectivity with a maximum permissible quiescent current of 1.5 mA for the 2-wire sensor.
Isochronous Mode: The module does not support isochronous mode (application synchronized up to terminal).
Galvanic Isolation: It provides galvanic isolation between the channels and between the channels and the backplane bus, using an optocoupler.
