Connecting Digital Inputs/Outputs (Di/Do); Connecting Standard Digital Outputs; Connecting Digital Inputs/Outputs - HBM WTX120 Bedienungsanleitung

S The load cells and load receptors, terminal boxes and weighing terminal
must be integrated into the potential equalization of the plants. Depending
on the local conditions, it may be necessary to lay a separate potential
equalization line with a corresponding cross-section (e.g. 16mm@) for this
purpose.
S Use only metal terminal boxes to extend cables, and fit the shielding for
both cables in the screwed cable glands.
S The cable must be laid a minimum of 50cm from power lines. Lay cable in
grounded steel conduit, metal tubing or metal cable ducts.
S The + and – signal connections must be swapped when load cells are under
tension rather than compressive loading.

Connecting digital inputs/outputs (DI/DO)

The WTX120 has a maximum of four digital inputs/outputs. The following
configuration levels are available independently of the primary PROFINET,
EtherNet/IP, PROFIBUS DP and Modbus TCP interfaces:
S Two permanently installed digital outputs (DO) in every version
S 2 x DO + 2 x DI, if analog output option available
S 4 x DO + 4 x DI, if DI/DO option available
