(1) Digital Inputs are either 24V DC (1132C) or 115V AC (1132D) based on module catalog number. Verify applied voltage is correct
for I/O module.
(2) Differential – External source must be maintained at less than 160V regarding PE. Input provides high common mode
immunity.
(3) For CE compliance use shielded cable. Do not exceed cable length of 30 m (98.4 ft).
(4) I/O Module parameters also have a port designation.
ATTENTION: Risk of equipment damage exists. Verify that the correct
voltage is applied to the I/O Module digital inputs. See the I/O Module
catalog number to determine the voltage rating.
