It is now possible to verify the proper
operation of traffic signal load switching devices with the 435C
Load Switch Analyzer.
General:
Load switches, flashers and transfer relays can be conveniently
checked on the 435C Load Switch Analyzer. The test is initiated
by inserting a device into the appropriate front panel connector.
A four scale meter with ranges of 0-30 volts DC, 0-30 ma DC,
0-10 and 0-50 ma AC is provided to monitorvoltage and current.
A flasher when inserted in its receptacle runs continuously
and the AC output current is monitored.
When a transfer relay is under test its contacts are checked
for continuity and the AC output current is monitored.
