BENTLY NEVADA DC Power Input 2155/40-02

Description

TDISecure with DC power input (Model: 2155/40-02) is an industrial-grade data acquisition unit that provides 24 channels of configurable direct analog inputs. It is engineered to interface with various signal types such as 4–20 mA current loops and voltage ranges from 0–10 V, enabling precise signal capture in process control and monitoring environments. The device operates efficiently on a DC power supply between 20–36 VDC and is optimized for both accuracy and durability in extended operating conditions. Its compact form factor and wide environmental tolerance make it well-suited for fixed installations in harsh industrial settings.
