Main features

Over/Under Temperature Protection

When the temperature goes above or below the set value (high limit or low limit), the CB100L will interrupt or remove the power from the process.
This output can be used for alarm or interrupting power to the heater circuit.
For safety reason, the output will be retained until reset operation is executed even when the measured value goes back to the normal range.
Reset operation can be executed by front key operation, communication, or digital input.

Closely contacted mounting is available

Closely contacted mounting has been realized to efficiently utilize the panel space.

Communication function (RS-485) is available (Optional)

Up to 31 controllers can be multidrop connected over the RS-485 communication line.

Communication protocol can be selected from RKC standard or MODBUS protocol.
