This wall charger allows ac power to serve as the power source for the SC532A. The 15966 is an ac/dc transformer that accepts inputs from 90 to 260 Vac @ 47 to 63 Hz, then outputs 12 Vdc @ 880 mA for use by the SC532A. Its cable has a barrel plug that connects the transformer to the SC532A; cable length is 6 ft. The 15966 replaced the 13869.
The 14291 Field Power Cable has a barrel connector on one end for attachment to the SC532A. On the other end, the cable terminates in two wires (12V and GND) for attachment to a power supply. This cable is intended for field use when ac power is not available for the SC532A's wall charger. The 14291 allows any 12 V power source that shares a common ground with the datalogger's power supply to be used. Cable length is 2 ft.
The 14020 Field Power Cable has a barrel connector that attaches to the SC532A and a 9-pin connector that attaches to the datalogger's CS I/O port. This cable is intended for SC532A field use when ac power is not available for the SC532A's wall charger. The 14020 allows the datalogger's power supply to be used.
