Features

Good immunity from electomagnetic interference: With its high isolation performance, Schneider 140DDI85300 can effectively resist various electromagnetic interferences in industrial sites. In industrial production, the electromagnetic vulnerability provides a significant contributor to systih'mic failures and malfunctions. The high isolation design assures the input signals remain undisturbed by external interference so that it can present a stable and reliable signal source to the control system.

Fast response and switching capability: The response time from state 0 to state 1 and back is only 4ms and the switching frequency stands at <= 100Hz. Such performance parameters allow it to capture any subtle change in an external signal in no time, feeding such changes back to the control system instantaneously.

High strength electrical isolation: Schneider 140DDI85300 renders superb performance, isolation-wise. Between the group and bus, an isolation up to 2500Vrms DC for 1 minute and between different groups, 700Vrms DC for 1 minute. Such high isolation performance creates an enabling environment in industrial scenes with complicated electromagnetic habitats.

Application

Building Automation System: Schneider 140DDI85300 gathers status signals and sensor signals of air conditioning systems, ventilation systems, lighting systems, water supply and drainage systems, etc. Such signals are needed in the intelligent control and energy management of the building environment and to improve comfort and energy utilization efficiency.

Traffic Signal Control: Schneider 140DDI85300 collects the status signals of traffic lights and induction signals of vehicle detectors in the traffic signal control system: allowing intelligent control and optimization of flow, improved road capacity, and lessened congestion in traffic.

Mechanical Processing: Schneider 140DDI85300 monitors the tool status of machine tools, workpiece clamping and release signals, pressure signals of hydraulic systems, etc., for timely equipment failure detection and abnormal condition monitoring, thereby ensuring the normal operation of machine tools, and improving processing accuracy and production efficiency.

Power System: The state of electrical equipment in the substation, such as position signals from circuit breakers and switches, action signals from protection devices, etc., is monitored by Schneider 140DDI85300 to provide data support for automatic control and dispatching of the substation and thus improve power supply reliability of the power grid.
