Digital interfaces are equipped with 50-pole connectors (KS) and offer numerous advantages, such as:

• Redundancy: the interfaces have 2 50-pole (AKB) connectors for redundancy purposes.
• Many of the interfaces activate a relay to indicate if one of the two possible power sources has dropped below a value of approximately 12 V.
• The cards can be mounted via tension clamp or screw connection.
• Multiple functions are integrated: isolators, fuses with status indicator, relay and status LEDs.
