Output Signal

PIN No. 2-10, 5-13, 6-14

There are 3 kinds of output signals : “Motor Connection Monitoring”, “AUTO MODE” and
“Unit Power Source Monitoring”.  
These signals are pulsed transistor activation signals.
Voltage and Current Specifications 

• Applied Voltage (V max)

30VDC 

• Working Current (Ip)

100mA (Rotational Pulse 50mA)

Use an external power source for output circuits. It is recommended to use a separate
power from the one used for Input/Output Connector A. Please refer to Fig. 33 for
connections.

(2) Input/Output Signals

Emergency Stop Signal Input

PIN No. 1-9

This signal is a switched 24V DC output.  
Please use a separate power source that is capable of supplying 24VDC±10%, 
25mA (5mA/circuit). Refer to Fig. 34 below for connections.
Normal Operation circuit is ON (Closed) Emergency Stop circuit is OFF (Open). 
If the Emergency Stop Signal is OFF (Open) the Safety Relay is OFF and the power supply
to the motor is interrupted and the motor stops.

2. Connector B

If you use NE211-OP1 connected to a machine tool, connect the signal line of SAFE-1A, 
SAFE-1B, SAFE-2A, SAFE-2B to the safety circuit at the side of the machinery in order to build
a safety shutdown system with higher reliability.

(1) Input/Output Connector B 

CAUTION

When using 0V DO NOT connect to PIN10 or 13 (Internal Ground) of Input/Output
Connector A.

CAUTION

NE211 does not use PIN No. 1, 3, 4, 9, 11, 12.
NE211-OP1 use PIN No. 1, 3, 4, 9, 11, 12.
