Switcher for 70MHz and 140MHz
Us for details.
Intended for use
with crystal detectors for monitoring IF levels between 70 and 140Mhz
for up to 6 channels. IF inputs from -29dBm to -10 dBm nominal, 75
ohms can be handled. Relay contact closure outputs are provided for
each channel to indicate an alarm or low IF level condition. The
panel is equipped with dual redundant power supplies to enhance
reliability. A separate alarm output is provided to indicate a
failure of either power supply or that the unit has no power. Analog
out puts are provided for each channel.
Designed for use
at a remote station where it can check for alarms generated by
on-site equipment. If an alarm is detected, the Station Monitor uses
an internal modem to automatically telephone designated equipment
such as a computer in the main office. The main office may then send
commands to the Station Monitor or to the monitored equipment via the
Amplifier Module (RFA01)
amplifying the signal from a crystal detector, providing a linear
analog voltage output proportional to the RF power applied to the
detector and sensing high or low RF conditions. Relay contact closure
outputs are provided to indicate alarm conditions.
Sensor module (TMP01)
sensor module is intended for measuring temperature, providing a
linear analog voltage output proportional to temperature and sensing
under or over temperature conditions. Relay contact closure outputs
are provided to indicate an alarm condition.
