4.2.1
Card Edge Connector & Socket Headers
For implementation of the «EPOS4 EtherCAT Card», a PCIe 2x18 position connector is required.
EPOS4 modules are available with two different types of socket headers.
•
EPOS4 Module 24/1.5
(536630) and
EPOS4 Module 50/5
(534130) feature 1.27 mm box
headers.
•
EPOS4 Module 50/8
(504384) and
EPOS4 Module 50/15
(504383) have pin headers that per-
mit two ways of mounting. They can either be plugged in a socket header or be directly sol-
dered to a printed circuit board.
Find further details on the hardware in the
separate document «Hardware Reference» of th e respec-
tive EPOS4 Module.
4.2.2
Supply Voltage
For voltage supply of the «EPOS4 EtherCAT Card», you may employ the EPOS4 Module’s power sup-
ply. For details
separate document «Hardware Reference» of the respective EPOS4 Module.
If you intend to use another source as power supply, we recommend to connect a TVS (transient voltage
suppressor) diode (D1) to the voltage supply line to protect against overvoltage resulting from voltage
transients or brake energy feedback.
