Insulation mode

Between inputs and outputs: Photocoupler and transformer insulation,
Between input channels: Photocoupler and transformer insulation

Other functions

Heater wire breaking alarm, control loop wire breaking alarm, measured value bias,
output limit, slope setup, manual reset, output control when an error occurs

Internal current consumption

Approx. 270 g

*1 Can be set for each channel.
*2 Because the alarm output is used as cooling control output when heat/cool control is used, the alarm output cannot be used as an alarm output function.
*3 Standby operation ON/OFF can be selected in each alarm mode.
*4 Use a KEYENCE sensor (OP-6694). (Sold separately.)
