Table 81 - TB2 Terminal Designations (One Relay and Two Transistor Outputs: 1R2T)
(1) Digital Inputs are either 24Vs DC (2262C) or 115Vs AC (2262D) based on module catalog number. Verify applied voltage is correct
for I/O module.
(2) See HW Input PTC on page 268
for PTC data.
(3) Differential Isolation – External source must be maintained at less than 160V with respect to PE. Input provides high common
mode immunity.
(4) For CE compliance use shielded cable. Do not exceed cable length of 30 m (98.4 ft).
(5) 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.
