The Model 650 Loop Power Supply provides DC power for instrumentation control modules. Each option provides three output selections. For example the Model 650-240-24 has output options of 24 VDC regulated, 32 VDC unregulated, and 60 Hz pulse at 46 peak volts (See datasheet for all output selections). All outputs for the Model 650 are floating, electrically isolated from ground. A power status indicator (LED) is located on the top of the unit. The POWER LED comes ON when power is applied. Applications for this device include two-wire current loop transducers, such as pressure, voltage or current. The Model 650 may also be used with alarm indicators, meters and timers.. Specifications: Mount: 8-Pin; Voltage Range: 120VAC
