Frequently Asked Questions
How many digital inputs does 6ES7321-1BH10-0AA0 have?
It has 16 isolated digital inputs.
What input voltage does this module use?
The rated input voltage is 24 V DC. Signal "0" is -30 to +5 V, and signal "1" is 13 to 30V.
Which front connector is required?
A 20-pin front connector is required.
Does the module provide channel-to-channel potential separation?
No. The digital inputs are not potential-separated between channels, while the channels and backplane bus are isolated by an optocoupler.
