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 type is SINK, DO1 supports high-speed pulse output; DO2 can be
used to control the direction of the stepper motor. DO default is sink,can control ≤24V DC ≤0.5A relay
directly ,otherwise must connect external relay.
3) The model number: M240T, M340T support thermal resistance temperature transmitter default type: PT100,
optional: PT1000, if you need PT1000 type of thermal resistance, please note when ordering.
4) All models support the register mapping, can extend I/O or meters via Modbus RTU protocol.
5) Each model’s I/O port qty is referred to the above table only. As MXXT series use same housing, those I/O
port hardware terminal blocks on the device which not described in the table is not valid.
