Wiring
INPUT WIRING: maximum distance of 300m (1000ft)
from the Input Expander when using 22 AWG.
AUX WIRING: Min 22AWG Max 16AWG.
(Depends on length and current consumption).
For wire/cable size, a maximum of 5% voltage drop at
the terminals of the powered device has to be observed.
MODULE NETWORK WIRING: Recommended
Belden 9842 or equivalent. 24AWG twisted pair with
characteristic impedance of 120ohm or CAT5e / CAT6
are also supported for data transmission when using
ground in the same cable. Max 900m (3000ft).
Do not use extra wires to power devices.
Address Configuration
The module address is configured via programming and will require reference to the
module serial number. The serial number can be found on the identification sticker on the
side of the module.
Please refer to the system controller configuration guide for address programming details.

Dual Stack Connector Warning
This half DIN rail product employs an economical dual stack design which accommodates a double layer PCB with
two rows of connectors. This requires the use of a specific connector configuration in which the design of the
upper connectors is slightly different to the lower connectors. Pin positions on one row are incompatible with the
connections on the other, and swapping upper and lower connectors may damage the connectors and the PCB.
Please check carefully before inserting connectors as incorrect placement can cause damage to the PCB.
