2. Input, output, and measurement specifications
-1. Basic specifications
Number of input
channels
15 (Set voltage, thermocouple, humidity, resistance temperature detector, or resistor for
each channel.)
Input terminals Push-button type terminal block (4 terminals per channel), outfitted with terminal block
cover
Measurement target Voltage
Thermocouples (K, J, E, T, N, R, S, B, C)
Humidity (using the Z2000 Humidity Sensor)
Resistance temperature detector (Pt100, Jpt100, Pt1000)
(Connection: 3-wire/4-wire)
(Measurement current: 1 mA ±5% [Pt100 and Jpt100 measurement];
0.1 mA ±5% [Pt1000 measurement])
(During Pt1000 measurement, setting available when the data refresh interval is
greater than 100 ms.)
Resistor (connection: 4-wire; measurement current: 1 mA ±5%)
Input type Scanning by semiconductor relays, floating unbalanced input
All channels isolated (The SoL terminals used to measure resistance temperature
detectors and resistors are not isolated as they are shorted for all channels internally.)
A/D resolution 16 bits
Maximum input
voltage
±100 V DC
Maximum channel-to-
channel voltage
300 V DC (The SoL terminals used to measure resistance temperature detectors and
resistors are not isolated as they are shorted for all channels internally.)
