4.2 Operating Modes

The 8020-59 has three modes of operation: single channel mode, 16-Channel mode, and 32-
Channel mode. Each operation mode is detailed in the subsections below.

4.2.1 Single Channel Mode

In this mode (Figure 13), the 8020-59 will maintain continuous excitation of the VW
transducer and provide a continuous 0-5V and 4-20mA output to the host DAS, updated
approximately every second.
By controlling the ENABLE input to the 8020-59, the 8020-59 voltage and current
outputs (VOUT and IOUT) will either be proportional to the transducer's digits
(ENABLE=0V – or disconnected) or the transducer's temperature in degrees Centigrade
(ENABLE=5V).
By controlling the CLOCK input to the 8020-59, the 8020-59 will either be ON
(CLOCK=0V − or disconnected) or OFF (CLOCK=5V).
