KT (AKT2,4,7,8,9,4H,4B)
2
PRODUCT TYPES
1. KT2 Series
* When heating/cooling is selected, alarm output 1 cannot be used.
When the communication function is selected, alarm output 2 cannot be used.
• Part No.
(Ex) Part No. when the optional functions (of Heating/Cooling control: relay contact output + Communications function) is added on to
the basic model are as follows; Part No.: AKT21110101
• Options
Note: When Current input is specified, a shunt resistor (sold separately) is required.
2. KT4 Series
Notes: 1. CT1 or CT2 for current detection is provided as an accessory when heater burn-out alarm function is added.
2. Event output will be shared if you choose alarm output 2 and the heater burnout alarm.
• Part No.
(Ex) Part No. when the optional functions (of Heating/Cooling control: SSR output + Communications function) is added on to the
basic model are as follows; Part No.: AKT41111401
• Options
Note: When Current input is specified, a shunt resistor (sold separately) is required.
