3 Analog Inputs + 1 Discrete Input
The OleumTech® OTC Wireless Analog/Discrete Transmitter is a self-contained, battery-powered solution for remotely monitoring up to three 0-5 Vdc analog and one discrete input signals. The WT-AD1 delivers up to 9.5 Vdc of power to connected analog sensors. You can calibrate both the zero and max analog point values.
The discrete input is ideal for connecting to a dry contact or open-drain output/NPN source for monitoring state changes. It can be set to normally open or normally closed mode. This ultra-low-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 local data access.
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.
