- IV2000 – current-to-voltage converter board (5A to 10V standard) for use with the RTU3220 when analog input is current rather than voltage. This board is also suitable for other non-RTU3220 applications where an accurate current to voltage conversion is needed. Converter ratios of 10A to 10V and 1A to 10V are also available (minimum order quantity of 10).
- H2000 – wiring harness with four ft. lead for wiring inputs to the RTU3220. The harness terminates in male Molex connectors that connect to the RTU input connections.
