Safety control unit
471 M41 H31
for 4 to 32 sensors, with safety and control outputs
+ PLe according to EN ISO 13849-1
+ Four safety outputs (two separate safety circuits each
with two safety outputs)
+ Separate control outputs for further processing
+ Emergency stop function with short-circuit detection
+ Suitable for 2-hand control
+ Connection via codable, screwless terminals
+ Available as an option with double terminals
+ LED status display
+ Adjustable delay times for safety output 4
+ Suitable for sensors with 2 NO system, input 4 also
suitable for NO/NC system
+ Monitoring of the contactor externally
Use
The control unit is for evaluating signals from machine safety
sensors. Due to the variable design, the inputs can be used for
a variety of functions, such as 2-hand control or for connecting
an emergency stop button.
Models
The 471 M41 H31 enables the connection of a sensor in 3- as well as 4-wire technique. The 4-wire
technique also allows a cross short detection. At sensor input 4, a sensor with 2-contact makers as
well as a contact maker/breaker system can be connected. Further parameters, such as the delay
time, can be configured by a DIP switch. The connection terminals are available as an option and
also as double terminals (1.5 mm²).

Connection type
Connection terminal
0.2 - 2.5 mm²
Double terminal (optional)
0.2 - 1.5 mm²
The plug-in, screwless terminals can be coded using coding
pins so that if the device is replaced, the connectors cannot be
confused during installation.
Double terminals are also available as an option (see adjacent
figure).
The 471 M41 H31 consists of two independent units:
Shown with double terminal
Unit 1
Sensor input 1
For sensors with 2 NO system
Sensor input 2
For sensors with 2 NC system
Safety output 1
Controlled in parallel by sensor inputs 1 + 2
Safety output 2
External contactor 1 + 2
For monitoring the external contactors
Control output 1
Output sensor 1, switched state
Control output 2
Sensor input 3
For sensors with 2 NO system
Sensor input 4
For sensors with 2 NC system
Can also be used as 2-hand control
Unit 2
For sensors with NO/ NC system
For 3 or 4 wire technique
For operating an emergency stop button
Safety output 3
Safety output 4
Delay time can be adjusted (0-15 seconds), as opposed to safety output 3
For monitoring the external contactors
For S4 emergency off: it is advisable to include a start button
Control output 3
Control output 4
Remarks
In the event of emergency off in 4 wire technique: cross short detection
2-hand control, simultaneous emergency stop and sensor(s) possible
Separate output available for standby

Start
The turn-off delay of safety output 4 can
be set via switch 1 to 4. See example here
for 4 seconds.
Cross short safety: emergency stop messages appear via two contact breakers which
are impacted by various potentials. This allows cable short circuits to be detected.
