The DS 1255 captures analog field signals inside Schneider’s industrial control hardware range. This module measures roughly 9.4 inches long, 1.2 inches wide, and 5.5 inches high. Moreover, it weighs about 0.8 pounds, which suits standard rack installation. Engineers specify the DS 1255 when they need accurate readings from temperature and pressure transmitters.
Technical Specifications and Interface Details
The module converts analog field signals into digital values for the host processor. Specifically, it provides multiple input channels with high common-mode rejection. Additionally, it accepts voltage and current ranges through configurable settings. A front-facing terminal block simplifies wiring and routine maintenance.

Energy Storage and Measurement Stability
Internal capacitors on the DS 1255 provide local energy storage for clean reference voltages. Consequently, the module suppresses noise from drives and contactors on the plant floor. This buffering supports stable readings across fluctuating supply conditions. The design therefore maintains measurement accuracy during extended operating cycles.
Installation and Compatibility Notes
Because the DS 1255 slides into standard Schneider racks, technicians complete installation quickly. They should verify input wiring before they power the control system. Furthermore, the module integrates smoothly with existing Schneider control hardware. Always store spare units in anti-static packaging to protect sensitive circuitry.
