Alarms: There are four standard alarms: transmitter output level (TX Fail), low received signal level
(Low Sig), communications channel failure (Logic Alarm), and power supply failure.
Alarm Relay Characteristics:
Maximum continuous current; 1 Amp
Maximum breaking current (125 Vdc): 1 Amp, non-inductive
Maximum breaking current (280 Vdc): 0.25 Amp, non-inductive
Maximum open circuit voltage; 280 Volts
Interface Dielectric Strength: All input and output circuits are isolated from ground and from all other
circuits. Breakdown is 1500 Vrms @ 50/60 Hz, 2500 Vdc, and 2500 Vrms @ 1.5 MHz, in
