Loop Power
In many cases, a 24VDC power supply must be provided to excite
the current loop. ADS highly recommends using the ADS Power
Supply (ADS p/n 5000-0728), which provides both the 12VDC
external monitor power and the 24VDC loop power from a single
sealed enclosure. If customer equipment, such as an RTU, PLC, or
chart recorder, already supplies loop power, an external 24VDC
supply is not required. A customer-supplied loop power supply can
be used if the power available to the monitor is at least 1A at the
monitor.
Signal Connection
Warning: ADS uses Belden and Alpha cables to
manufacture I/O cables (ADS P/N 5000-0698). Each
manufacturer uses unique colors for the internal conductor
insulation of the analog output wires. Failure to observe
this difference could result in damage to the system.
Therefore, before making any connections, identify the
cable type based on the permanent labels (reading
BELDEN or ALPHA) affixed to the cable jacket. Refer to
one of the following color code charts based on the cable
type:
