- Cost Effective Solution
- High Accuracy
- Manual Output Override
- Loop Current Indication
- Small Size and Easy Installation
The ETVI two channel board converts analog voltage, typically 0 to 10 VDC, to an industrial standard 4-20 mA signal.
This board can be used to interface a generic DDC panel that provides voltage output with any loop current driven device.
The ETVI board accepts voltage signals (typically 0-10 VDC) and provides 4-20 mA two wire current output. The board is equipped with LOCAL-AUTO switches with LOCAL position indication. In this manual mode, the output current can be precisely modulated by a trim pot located on the board.
The loop current is indicated by large amber LEDs. The maximum loop resistance is over 600 Ohm.
The ETVI board contains two identical channels. It is equipped with angular connectors for fast and easy wiring and mounts in a 2.75" wide snap-track (provided).
