Model Number Structure

NR 1-2.3.4.5.6.7.8.9.10.

1. Models
NR2 : 48(W) x 96(H) x 100(D) mm.
NR4 : 48(W) x 48(H) x 76(D) mm.
NR7 : 72(W) x 72(H) x 76(D) mm.
NR9 : 96(W) x 96(H) x 100(D) mm.

2. Control output (initial factory setting only)
M : Relay contact output(Standard)
S : Pulse voltage output for SSR (0 or 12V
DC repetition)
C : 4-20mA DC current output

3. Control output2*1 (initial factory setting
only)
N : None (Standard)
M : Relay contact output
S : Pulse voltage output for SSR (0 or 12V
DC repetition)
C : 4-20mA DC current*2

4. Alarm output1 (ALM1)
P : Relay contact output

5. Alarm output2*1 (ALM2) (initial factory
setting only)
N : None
P : Relay contact output

6. Transmission output (initial factory setting
only)
N : None
P : 4-20mA DC current output
A 250-ohm resistor is required for 1-5V DC.

7. Heater failure alarm (initial factory setting
only)
N : None
P : With heater failure alarm (for single
phase)
Q : With heater failure alarm*2 (for dual
phase)

8. Event input (initial factory setting only)
N : None
P : With event input

9. RS485 serial interface (initial factory
setting only)
N : None
P : With RS485

10. Front face panel
W : White
B : Black

*1 The control output is mutually exclusive with the alarm output for NR4, so select either one or the other
*2 None for NR4
*3 To control temperature by current input (4-20mA DC or 0-20mA DC), NR series requires connection of an external receiving resistor of 250 ohm to the input terminal. This resistor does not come with the product, so the resistor should be provided by the customer.
