 |
The CN7400 Series temperature/process
FM-approved limit controllers set a new
standard in 1/16 DIN limit controls. They
have universal inputs (10 thermocouple
and 4 RTD types, voltage, and
current). Standard features include
remote reset capability. Outputs
include normally open (form "A") and
normally closed (form "B") relays. Form
"A" and form "B" relays can be set up
for each setpoint output and logically
linked to emulate a form "C" output.
