For the single channel inputs, the two 4-20 mA outputs are both proportional to the single input.
Control action either a 5A relay, 4-20 mA current, or pulsed 24-VDC to drive a solid-state relay.
The Model 2000 has analog outputs in 0-30 mV, 0-5 V and 4-20 mA.
The outputs can be field configured for DC signal ranges of: 0-10 V, 0-20 mA, or 4-20 mA.
The controllers can be used with any sensor or device that produces 020 mA, 4-20 mA, 0-10V or 2-10V analog output.
The BlueLynx system transmitter module can connect to a dynamic sensor, such as an accelerometer, or up to four standard 4-20 mA sensors.
Onset offers more than 60 models of data loggers to measure temperature, humidity, light, AC current, carbon monoxide, 4-20 mA, voltage, on/off, open/closed, and events.

Jewel Instruments (Manchester, NH) has introduced the model SMI-L 4-20 mA Force Balanced Inclinometer.
The new GL42 low differential pressure indicating transmitter mates a four-digit LCD to a stable transmitter to provide a local reading as well as a 4-20 mA output.
Additional features of these Gil AS-Interface modules include automatic scaling to 4000-20000 for 4-20 mA, 0-10000 for 0-10 V, and -2000 to 8500 for - 200 [degrees] C -+850 [degrees] C; user-selectable 0-20 mA or 4-20 mA input option; inputs powered by AS-interface or auxiliary, dip switch (user-selectable); and a unique G11 O-ring sealing technique that makes these modules impervious to water, dirt and oils.
To improve the resolution of a PLC or data system, the 4-20 mA signal can be changed in the field to spans of either 0 to 1.
