ZeroDT

ZeroDT 12-1 & 12-2

The design of the ZeroDT 12-1 utilizes the latest generation, non-degrading Silicon Avalanche Suppression Diode (SASD) stack array encapsulated in urethane, to protect transmitters, gas detection sensors & systems, level equipment, flow measurement devices as well as other field instrumentation transient over-voltages. This SASD technology provides continuous, bi-directional (eliminating installation issues), and bi-polar (both positive and negative) protection that returns to its original state (no loss or degradation of protection) once the over-voltage has passed. The unit is designed to limit the energy of these over-voltage surges on 4-20 mA current loops, and RS-485/422, DeviceNet, Fieldbus communication lines as well as low voltage DC power lines. The module is small enough to allow it to be mounted directly into a measurement device’s explosion-proof housing or other small electrical housings, eliminating the need for additional enclosures and getting the protection as close as possible to the device to allow for the best possible protection.

Nominal Voltage: 12 VDC
Maximum Continuous Operating Voltage: 18VDC
12.4 mm H, 12.4 mm W, 18.9 mm D
1-Green Wire Ground, 1-Red Wire (Positive/Negative), 1-White Wire (Positive/Negative)

ZeroDT is a leader in industrial surge protection. Boasting a response time of less than five nanoseconds, our American-made products are engineered to protect critical power and communications systems from overvoltage. Our solutions have earned us the trust of some of the world’s largest companies for applications that include oil and gas refining, aerospace, and water/wastewater.
