The CE8 is an 8-channel current excitation module designed to provide a 50 mA constant current to the heating element of a 229-L Heat Dissipation Water Matric Potential sensor. Features Sources current for up to eight 22...

The CE4 is a 4-channel current excitation module designed to provide a constant current to the heating element of a 229-L Heat Dissipation Water Matric Potential sensor. Features Sources current for up to four 229 probes...

The A547 interfaces a single CS547A or CS547 (retired) to a datalogger. If many conductivity probes are required in the application, the A547 can be positioned between an AM16/32 multiplexer and the datalogger to provide...

The CVD20 provides terminal strip connections and voltage reduction for up to twelve single-ended or six differential channels. Voltage reduction is 20-to-1; the on-board resistors are 0.1% 19 kohm and 1 kohm. Specificat...

The SW12V allows a datalogger control port to control the status of an internal switch, thereby controlling whether 12 Vdc power is passed to an external peripheral. The SW12V is used with the HMP45C Air Temperature and ...

The LLAC4 is a small peripheral that increases the number of low-level ac signals a datalogger can monitor. The module enables four datalogger control ports to emulate pulse counting channels by converting the low level ...

3WHB10K Half-Bridge Module The 3WHB10K provides the completion resistor required for a 3-wire half bridge measurement. The completion resistor has a resistance of 10 kOhms with a tolerance of ±0.01%. Features Connects di...
