The modules are available in 24VDC and 12VDC versions and come with an integrated lithium-polymer battery module. Status LEDs indicate the operational condition. In addition, the status can be communicated to a supervisory control system through integrated status contact. Battery runtime can be adjusted via a rotary dial to prevent over-discharging.
