Selecting the Range and Type of Input
The following types of input can be selected. The default setting is VOLT.
• SKIP
Measurement, data saving and display (except for page display) will not be carried
out. Measurement, data saving and display will be carried out for the next channel
whose input type is not set to SKIP.
• VOLT (DC voltage)
This input type can be selected from 20mV, 60mV, 200mV, 2V, 6V, 20V and 50V. Refer
to chapter 14 for the measurement range of each setting. The default setting is 2V.
• TC (thermocouple)
This input type can be selected from R, S, B, K, E, J, T, N, W, L, U and KP (KPvsAu7Fe).
Refer to chapter 14 for the measurement range of each setting. The default setting is R.
• RTD (resistance temperature detector)
This input type can be selected from PT1 (Pt100 1mA), PT2 (Pt100 2mA), JPT1 (JPt100
1mA), JPT2 (JPt100 2mA), PT50 (Pt50 2mA), NI1 (Ni100 1mA SAMA), NI2 (Ni100
1mA DIN), NI3 (Ni120 1mA), CU1 (Cu10 GE), CU2 (Cu10 L&N), CU3 (Cu10 WEED),
CU4 (Cu10 BAILEY), PT1S (Pt100 1mA high resolution), PT2S (Pt100 2mA high
resolution), JPT1S (JPt100 1mA high resolution), JPT2S (JPt100 2mA high resolution)
and J263B (J263*B). Refer to chapter 14 for the measurement range of each setting.
The default setting is PT1.
• DI (select LEVL (voltage level) or CONT (contact)
For LEVL, a voltage of less than approx. 2.4 V will be recognized as “0 (OFF)”,
whereas a voltage of approx. 2.4 V or more (max. allowable voltage is up to ±60 VDC)
will be recognized as “1 (ON).”
For CONT, an open, externally connected contact to which no voltage is applied, will
be recognized as “0 (OFF)”, whereas a closed contact will be recognized as “1 (ON).”
The default setting is LEVL.
• mA (DC current, mA input module)
This input can be set only for mA input channels. The measuring range is -20 mA to
20 mA.
Setting the Wiring Method
Select from the following methods:
Single-phase two-wire (1Ph2W)
Single-phase three-wire (1Ph3W; 3-wire input modules only)
Three-phase three-wire 2 Voltage 2 Current (3Ph3W-2I; 3-wire input modules only).
Three-phase three-wire 3 Voltage 3 Current (3Ph3W-3I; 3-wire input module only).
Three-phase four-wire (3Ph4W; 3-wire input modules only).
Setting the Input Range
Select from the following ranges: 250V-0.5A / 250V-5A / 25V-0.5A / 25V-5A.
This setting is common to all channels. Any change to this setting also changes the
settings of the rest of the channels. Impose a voltage or current signal to the input
module within the limits you set here.
Note
If the connection method or input range is changed, alarm setting is turned off.
