2x Discrete Inputs

The OleumTech® “DS1” Discrete Transmitter features two discrete inputs for connecting to a dry contact or open-drain output/NPN source for notifying state changes. The digital inputs can be set for normally open or normally closed. The wireless transmitter can also report transition counts. The DS1 utilizes on-delay exception reporting method and users can set the debounce filter ranging from 20 ms to 2000 ms to control exactly when the state change occurs. As a safety measure, regardless of state change, this device reports to the wireless gateway every five minutes. This ultra-lower-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life. The push button LCD interface allows for device configuration and instant access to process data.

Reliable, Scalable and Safe

The field-proven wireless sensor node communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network, creating a highly scalable network, accommodating virtually any I/O requirement. The OleumTech Wireless Transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process.

This product is also available without a local display.
