DVP04TC-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device
(e.g. key or specific tools are required to open the enclosure) in case danger and damages on the device may occur.

9

DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all
the wiring again before switching on the power.

9

DO NOT touch any terminal when the power is switched on.

9

Make sure the ground termnial

9

Keep the wire as short as possible between RTD and PLC and the power wire as far away as possible from I/O wire to
prevent interference.

is correctly grounded in order to prevent electromagnetic interference.

There are 2 modes (J-type and K-type) for each channel which can be set up separately. For example, if the
user needs to set up CH1: mode 0 (b2 ~ b0 = 100); CH2: mode 1 (b5 ~ b3 = 001); CH3: mode 0 (b8 ~ b6 =
