Input

Thermocouple	K, J, R, S, B, E, T, N, PL-II, C(W/Re5-26) External resistance: 100 max. (for B input, 40 max.)
RTD	Pt100, JPt100 3-wire type (Allowable input lead wire resistance: 10 max. per wire)
Direct current	0 to 20 mA DC, 4 to 20 mA DC Input impedance: 50 max. Allowable input current: 50 mA DC max.
DC voltage	0 to 1 V DC Input impedance: 1 M min. Allowable input voltage: 5 V DC max. Allowable signal source resistance: 2 k max.
DC voltage	0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC Input impedance: 100 k min. Allowable input voltage: 15 V DC max. Allowable signal source resistance: 100 max.

Accuracy

Thermocouple	Within 0.2% of each input span 1 digit, or within 2 (4 ), whichever is greater However R, S inputs, 0 to 200 (32 to 392 ): Within 6 (12 ) B input, 0 to 300 (32 to 572 ): Accuracy is not guaranteed. K, J, E, T, N inputs, Less than 0 (32 ): Within 0.4% of input span 1 digit
RTD	Within 0.1% of each input span1 digit, or within 1 (2 ), whichever is greater
Direct current, DC voltage	Within 0.2% of each input span1 digit

Input sampling peirod

125 ms

Event input function

Selects Event input function from 3 types of HOLD function and 2 types of Alarm HOLD function. Not available if Serial communication (C5 option) is ordered.

A1 output,
A2 output,
A3 output

The alarm action point can be set at random (process alarm), and if the input reaches the randomly set action point, the alarm output turns ON or OFF corresponding to the alarm type and Energized/De-energized selection. The alarm type can be selected from; No alarm action, High limit alarm, Low limit alarm, High limit with standby alarm, Low limit with standby alarm and High/Low limit range alarm (for A3 output only). High/Low limit range alarm can be selected when A1 High limit alarm (High limit with standby alarm) and A2 Low limit alarm (Low limit with standby alarm) are combined, or when A1 Low limit alarm (Low limit with standby alarm) and A2 High limit alarm (High limit with standby alarm) are combined.

Action	ON/OFF action
Hysteresis	0.1 to 100.0 () Direct current, DC voltage input: 1 to 1000 (The placement of the decimal point follows the selection.)
Alarm HOLD function	Enables/Disables the Alarm HOLD function. If Alarm HOLD function is set to “Enabled”, and if the alarm is ON, the alarm output ON status will be maintained until the following is conducted. • The FAST key is pressed for approx. 3 seconds. • The power is turned OFF. • The HOLD is cancelled by the Event input function. During Alarm HOLD, corresponding alarm action indicator flashes.
Output	Relay contact 1a Control capacity: 3 A 250 V AC (resistive load) Electrical life: 100,000 cycles

Transmission output 1

Converting the PV to analog signal every 125 ms, outputs the value in direct current. (Unaffected by the HOLD function) (When using the Transmission output 1 value as an input for other instruments, check that the input impedance of these instruments is smaller than the maximum load resistance of Transmission output 1.)

Resolution	12000
Direct current	4 to 20 mA DC (Load resistance: Max. 550 )
Output accuracy	Within 0.3% of transmission output span
Response time	400 ms+ Input sampling period (0%→90%)
