- inputs)
- Linear mV voltages: 0-20mV, 0-50mV, 0-100mV, 0-1V (with J1 module)
- Linear voltage: 0-1V, 0-3V, 0-5V, 1-5V etc. (with J3 module)

- provides 24VDC power supply)
- Maximum lead wire resistance for RTD input
- 2-wire type RTDs: 2 Ohm for Pt100 or 0-400Ohm RTD input,1 Ohm for Cu50 or 0-200Ohm
- RTD input;
- 3-wire type RTDs: 5 Ohm
- Measurement range:
- K(0~1300℃), S(0~1700℃), R(0~1700℃), T(-200~+350℃), E(0~1000℃),
