State101A
PRODUCT USER GUIDE
Product Overview
The State101A data logger monitors and records the
occurrence, duration and status of predetermined events
by measuring changes in voltage. Typically connected to
a relay or switch, this data logger features a removable
screw terminal block to easily disconnect and retrieve
the logger for data download without disrupting wiring
connectivity.
The State101A is a great solution for a variety of industries
and applications including HVAC studies to monitor
heating and cooling systems for efficiency or the
monitoring of gas, water or electric pumps. This device
replaces costly strip chart recorders and is also used in TTL
high/low monitoring, general status recording and security
systems as well.
