EN PISA-B-8CL2-B4 Installation Manual
Product Description
The PISA-B-8CL2-B4 is a DIN-rail mountable eight channel protection module with integrated
electronic fuses for 24V systems.
The outputs of each channel fulfil the requirements for a limited power source acc. to NEC Class 2.
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or
threaten human life without additional appropriate safety devices, that are suited for the end-
application.
If this device is used in a manner outside of its specification, the protection provided by the device may
be impaired.
Installation Instructions
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on top of the unit.
Up to eight devices can be connected via two bus bars, where only the first device is connected to the
power supply. The bus bars must be long enough to make a connection to all contacts of the devices.
Use an appropriately sized 24V power supply, which can deliver the peak current required to trip the
load channels. If peak currents are too low, the supply voltage for the protection module can no longer
be maintained, which results in a malfunctioning of the protection module.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper
cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up to
+45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to +70°C.
Ensure that all strands of a stranded wire enter the terminal connection.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or
frost is allowed.
The enclosure of the device provides a degree of ingress protection of IP20. The housing does not
provide protection against spilled liquids.
The isolation of the devices is designed to withstand impulse voltages up to 1.5kV according to IEC
60664-1.
The input can be powered from a regulated power supply or a similar DC source.
The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to
maintain a SELV or PELV output.
Check for correct input polarity. The device will not operate when the voltage is reversed.
A disconnecting means shall be provided for the input of the device.
The device is designed as “Class of Protection III” equipment according to IEC 61140.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and
right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. Between multiple
PISA-B modules, no clearance is needed.
The device is designed for altitudes up to 5000m (16 400ft).
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the
same as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Functional Description
The output can supply any kind of loads, including inductive and capacitive loads. The maximum size
of capacitive loads is specified in the “Technical Data” table on the right. Larger load capacitors might
result in an unintended turn-off of the channel.
Do not apply return voltages from the load to the output terminals higher than 30V.
Do not parallel outputs for higher output currents.
Do not connect outputs in a series connection for higher output voltages.
Do not connect batteries for charging purposes to the output of the device.
Output channels can be switched on and off separately by pushing the corresponding control button
for longer than 50ms. A switched off channel is displayed with the uppermost red LED of the LED bar
graph.
The green and yellow LEDs of the LED matrix display indicate the channel current in percent of the
nominal value. Peak values are stored in a peak detector and are additionally shown with one LED for
a short period of time.
After an over-current trip, which is displayed with a flashing of the uppermost red LED of the LED bar
graph, channels can be reset either with the channel control button (push longer than 1s) or remotely
with the reset input. Resetting by means of the reset input is done by applying a voltage between 10
and 30Vdc (max. 6mA current consumption) for longer than 1s. The reset input is galvanically isolated
from the rest of the device.
The tripping characteristic can be set as a common parameter for all channels. To change the
characteristic alternately push the SET and channel control button for channel 3 at the same time. The
selected option is shown on the LED matrix for 2 seconds. Letter F indicates the fast and the letter S
the slow acting characteristic. If only the SET button is pressed, the characteristic is displayed for 2s.
Tripping characteristic setting can be protected against changes with a PIN code. To lock the settings
push the SET and channel control button 1 until the unit shows a moving text “PIN TO LOCK”. Enter a
4-digit PIN by pushing any combination of channel control buttons 1-8. Push the SET button to save
the PIN, the unit shows a moving text “LOCKED”.
To unlock settings push the SET and channel control button 1, the unit shows a moving text “PIN TO
UNLOCK” and enter the 4-digit PIN you selected and confirm it by pushing the SET button.
Factory settings are that all channels are turned on in fast tripping characteristic mode.
The device is equipped with a LED matrix display. This display provides information about the actual
current values (average and peak) of the individual output channels, reports faults and helps to
parameterise the device.
Technical Data
All values are typical figures specified at 24Vdc input voltage, 8x NEC

EN PISA-B-8CL2-B4 Installation Manual
The device is equipped with a “Digital Coded Alarm Signal” output (pins 13 and 14), which provides
information about individual channel tripping. The signal is an opto-coupler-type output which is low
ohmic for start bit and for tripped channels. The maximal signal current between pins 13 and 14 is
10mA and the maximal voltage is 35V.
The signal sequence starts with 200ms start bit followed by a 100ms gap and 100ms signal related to
CH1 etc. The whole sequence is periodically repeated every 1900ms.
