ZeroDT I/O-24 DIN Rail Mount

The design of the ZeroDT I/O-24 utilizes the latest generation, non-degrading Silicon Avalanche Suppression Diodes (SASDs) to protect electronic equipment and systems from transient over-voltages. The unit is designed to limit the energy of these surges on 4-20 MA current loops, and RS-485/422/232, DeviceNet, FieldBus communication lines as well as low voltage DC power lines. The unit easily mounts on a standard DIN rail and houses the 8 connection lugs (4 in, and 4 out) and the SASD suppression circuitry. 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 with usage) once the over-voltage has passed.

Nominal Voltage: 24VDC
Maximum Continuous Operating Voltage: 36 VDC
Protects two loops or 4-wires
Mounts to Grounded DIN Rail
Compression lugs accept #26 to #14 AWG conductors
