D1200 Current Input Modules


The D1200 current input modules contain an isolated 15-bit analog to digital converter and measure DC current with full scale input ranges from +/-1mA to +/-1Amp, including 4-20mA. Each module is hardware optimized for the best measurement performance over the full-scale input range. The module performs all signal conditioning, analog to digital conversion and linearizes the digital data into scaled engineering units. Five different current input ranges are available.

The D1200 current input modules include one discrete digital input and two open-collector digital outputs for monitoring On/Off signals or controlling solid-state relays and annunciators. The digital outputs can also be programmed to operate as HI/LO alarm outputs based on the input current level.

The digital outputs can be pulled up to +30Vdc and sink up to 30mA without damage. The discrete digital input contains an internal pull up resistor and can accept +/-30Vdc signals without damage. The input switching levels are <+1Vdc = logic “0”, >+3.5Vdc equals a Logic “1”.

The scaled current values are transmitted to a host computer via an RS-232 or RS-485 serial port.

Additional 4-20mA current input modules are available with advanced data scaling capabilities and higher channel counts for measuring larger quantities of sensors.  The D2200 and D5200 series current input modules contain advanced scaling capabilities, allowing users to scale the measurement data into engineering units that will match the application.  The D6200, D6400 and D8400 series modules contain higher channel counts for measuring larger quantities of 4-20mA signals.
