Module (6ES7 322-8BH01-0AB0) Specifications
This section contains changes to the I/O module specifications when it is used with the MTA.
Changes to 16-Channel, 24 VDC Discrete Output Module (6ES7 322-8BH01-0AB0)
Specifications when used with 16-Channel, 24 VDC Discrete Output MTA (6ES7650-1AD10-
2XX0)
Isolation between groups of 4 channels No
Data for Selecting an Actuator - Voltage with
output ON
L+ - 2.9 V minimum
(L+ is supply voltage at the MTA)
Total current of outputs with series diodes
Not applicable, only outputs without
series diodes are used. The total current
per group is 2A max., as specified for the
6ES7322-8BH01 module.
There are series diodes on the MTA;
therefore the behavior of the 6ES7322-
8BH01 module is like using outputs with
serial diodes. This affects the
applications with lamp loads and short
circuit diagnostics. See 6ES7322-8BH01
module manual.
Reverse polarity power supply protection Yes, see Note below.
Diagnostic with short circuit between the
channel output and M (common)
If output signal = "0", the M short circuit
diagnostic message is not reported.
Diagnostic with short circuit between the
channel output and L+ (24V supply)
A short circuit between the channel
output and L+ produce a "wire break"
diagnostic message.
Note
Connecting one reverse polarity power supply (e.g. -24 VDC to L+A) and one
correct polarity power supply (e.g. +24 VDC to L+B) will damage the MTA.
