Onset 4-20mA Input Adapter - S-CIA-CM14

Product Description

Onset 4-20mA Input Adapter - S-CIA-CM14

Overview
The 12-bit 4-20 mA Input Adapter interfaces with any sensor providing a 4-20 mA signal to connect to smart sensor compatible data loggers. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors, while offering digital filtering which improves measurement accuracy with 32 readings/sample and 60 Hz noise rejection.

Highlighted Features

• 12-bit resolution
• Digital filtering improves measurement accuracy with 32 readings/sample—4-20 mA adapter has 60 Hz noise rejection
• Measurement averaging over logging interval further enhances accuracy
• Plug-in modular connector for easy interface with HOBO® Weather Station or HOBO® Micro Station data loggers
• Screw terminal for connecting to sensors
• Micro Station has room for two adapters and Weather Station has room for ten (adapters mount inside station enclosure)
• Represents one data input channel
