Technical Data and Dimension Drawings
7.2 DHE21B/41B option
DHE21B/41B option
Part number • DHE21B option: 1823 607 3
DHE41B option: 1821 160 7
Electrical supply The following applies to all units (MDX, MX, compact controller):
• You have to supply the binary inputs and outputs separately with DC 24 V (X31:1/2).
Installed in MOVIDRIVE
®
MDX61B:
• Power consumption: P
max
= 6.8 W
• Option DHE21B/41B is supplied by MOVIDRIVE
®
MDX61B via backplane connector.
• In the case of disconnection from the power supply, continued function is guaranteed by the DC 24
backup mode (external DC 24 V supply to X10:9/10 of MOVIDRIVE
®
MDX61B required).
Installed in the MOVIAXIS
®
master module (MXM):
• Power consumption: P
max
= 8.5 W
• U = DC 24 V (–15 % / +20 %)
•I
max
= 600 mA
• Option DHE21B/41B can be supplied from the MOVIAXIS
®
switched-mode power supply (MXS) or
from an external voltage source. To do so, connect X5 between the individual units.
• If the DHE21B/41B option is supplied with DC 24 V from the MOVIAXIS
®
switched-mode power
supply, then the function of the DHE21B/41B option is ensured when power supply is switched off
(external DC 24 V supply at X16 of the MOVIAXIS
®
switched-mode power supply).
Potential levels Option DHE21B/41B has the following potential levels:
• Potential control / CAN 1 / COM1
• Potential COM2
• Potential binary inputs and outputs
• Potential system bus CAN 2
Memory • Retain data: 32 kByte
• System variables (retain): 8 kByte
Program memory:
• DHE21B: 2 MByte (for application program, incl. IEC libraries)
• DHE41B: 6 MByte (for application program, incl. IEC libraries)
Data memory:
• DHE21B: 4 MByte (for IEC application)
• DHE41B: 8 MByte (for IEC application)
Binary inputs Isolated (optocoupler), PLC compatible (IEC 61131-2), sampling interval corresponds to task cycle time.
X31:3 – X31:10 Can be configured as binary inputs or outputs
Internal resistance R
i
≈ 3kΩ, I
E
≈ 10 mA
Signal level DC (+13 V to +30 V) = "1" = contact closed (according to IEC 61131)
DC (–3 V to +5 V) = "0" = contact open (according to IEC 61131)
Binary outputs PLC-compatible (IEC 61131-2), response time 1 ms
X31:3 – X31:10 Can be configured as binary inputs or outputs
Maximum permitted output current I
A_max
= DC 150 mA per binary output
All 8 binary outputs can be subject to the maximum approved output current I
A_max
load at the same
time.
Signal level "0" = 0 V "1" = DC +24 V
CAN 2 system bus
X32:1–X32:3
• System bus CAN 1 and CAN 2 to CAN specification 2.0, parts A and B, transmission technology to
ISO 11898
• The CAN 2 system bus is electrically isolated
• Max. 64 stations (DHE41B) / 16 stations (DHE21B) per CAN system bus
• Max. 64 (DHE41B) / 16 (DHE21B) SCOM transmit objects / 256 receive objects per CAN system bus
• Address range 0 - 63
• Baud rate: 125 kBd–1MBd
• If X32 or X33 is the bus terminator, you must connect a terminating resistor (120 Ω) externally.
• You can remove connector X32 or X33 without interrupting the system bus.
• The system bus can be run in layer 2 (SCOM cyclic, acyclic) or in accordance with the SEW-
MOVILINK
®
protocol.
