Power Supply:
24 VDC ±20%, 80 ma maximum for both channels.
Loop Input:
The loop inputs incorporate lightning and transient protection devices and the loop
oscillator circuitry is transformer isolated. The lightning protection will withstand the
discharge of a 10 microfarad capacitor charged to 2,000V across the loop inputs or
between any loop input and earth ground.
