The TW850X provides a DC output current proportional to a frequency input signal with an optional display in a "hockey puck" case. Optional isolation is also available for the transmitter. The transmitter is protected by a gasketed, NEMA-4X glass-filled polyester housing and operates from -40°C to +85°C. The chopper-stabilized input amplifier provides accurate, low-drift operation.

All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning.

The output ZERO and SPAN controls are accessible through the top of the housing.

Optional conformal coating of the electronic components makes the TW850X extremely reliable and resistant to the corrosion, moisture and fungus associated with many industrial environments. A built-in pull-up resistor is provided to permit use with contact closure or open-collector inputs.

Terminations are made to screw terminal connectors on the top of the case.
