Status display

High accurate setting by 5-digit display Universal input New PID algorithms built-in

New learning type overshoot suppression function JyroNavi built-in

• MODBUS protocol communications for easy system configuration

• Remote contacts input and retransmission output are built-in as standard.

• Various functions are built-in for easy control.

• Only 7mm thickness of the front panel

• Conformance to CE, UL and CSA (UL, CSA: Approval pending)

• Water-proof conforming to NEMA250 4X (equivalent to IEC529 IP66) (option)

Note: For the current input, a 250Q shunt resistor (sold separately) is required.

* The heater disconnection (CT) is only applied to the Control output 1 of on-off pulse type or SSR drive pulse type.
