Models 8611, 8612
Type J & K Thermocouple to Frequency
Model 8611 Type J thermocouple to frequency converter is
designed to operate into the common 24 Volt, 7 mA PLC
inputs. It's ouput is an isolated optocoupler transistor and
provides DC isolation from the input and DC power. The 8611
will operate with a DC supply of 15 Volts to 26 Volts at 17 mA.
Model 8612 Type K thermocouple to frequency converter is
designed to operate into the common 24 volt, 7 mA PLC
inputs. The output frequency is linear to the temperature. It's
Model 8611 & 8612
Type J / K Frequency
output is an isolated optocoupler transistor and provides DC
isolation from the input and DC power. The 8612 will operate
with a DC supply of 15 Volts to 26 Volts at 20 mA.
The Model 8611 and 8612 modules are housed in a plastic
housing with a U-foot for mounting on standard DIN rails. The
unit's dimensions, excluding the mounting foot, are 1.65"H x
1.06"W x 3.78"L. Connections are made to screw clamp
terminal blocks.
