Special instructions for ordering

1)If the model provides digital input, the DIN default type: wet contact, optional: dry contact.

The input type cannot be changed after manufacturer delivered.

The DIN1 default is high-speed count mode; it can be changed to low-speed count mode by open the shell and change the internal jumper.

If require dry contact input, please note when ordering, if DIN1 require high-speed pulse count mode then must be wet contact.

2)If the model provides digital output, the DO default type: SINK, optional: Relay.

The output type cannot be changed after manufacturer delivered.

The DO1 supports PWM high-speed pulse output, the output duty cycle from 10-90%; DO2 can be used to control the direction of the stepper motor.

If require relay output, please note when ordering, if DO1, DO2 used for high-speed pulse output then must be Sink.

3)The model number: M240, M340 support thermal resistance temperature transmitter default type: PT100, optional: PT1000, if you need PT1000 type of thermal resistance, please note when ordering.

4)The valid number of I / O ports corresponding to the model number is described in the Model List, the not included I/O port in the model is invalid, although in the hardware reserved them.
