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.

Inputs

Note: All thermocouple and RTD inputs can be set for 0.1° display.
If temperature goes above 999.9° or below -199.9°, the display will
return to whole-degree resolution.

*

2 to 10 Vdc, and -10 to 10 mVdc inputs are fully scalable from a
minimum of 100 counts span placed anywhere within the range of

-1999 to 9999. Decimal point position is adjustable from the zero
place (9999), tenths (999.9), hundredths (99.99) or thousandths (9.999).
