        Features:

        • Sixteen potential-free relay channels each provide one changeover contact.
        • The switching ceiling is 60 V DC or 24 V AC with up to 2.5 A per channel.
        • timing is approximately 8 ms pickup and 5 ms release for the relay mechanism.
        The BA order code denotes the dry-contact output card used when galvanic separation or changeover logic is needed.

        An energized coil transfers its contact from rest to working position, giving the field circuit both NO and NC choices.

        Confirm voltage-specific fusing, 10 A group loading, inductive suppression and the original contact logic before commissioning.

        • Alarm circuits can use normally closed logic so loss of module power produces a detectable state change.
        • Contactors and valve interface relays can be commanded through isolated dry contacts within the switching limits.
        • Mixed low-voltage AC and DC control circuits can be kept electrically separate by assigning independent relay contacts.
        • Sixteen changeover contacts provide potential-free command paths between the TELEPERM controller and mixed field circuits.
        • Each relay channel offers a changeover contact, allowing normally open or normally closed control logic to be wired.
        • The module can interpose controller decisions to alarms, valves, contactors and circuits requiring dry-contact isolation.
        • The internal electronics operate from a 20 to 33 V DC supply within the specified TELEPERM rack arrangement.
        • Relay contacts can switch loads up to 60 V DC or 24 V AC when the permitted current and group limits are observed.
        • Individual channels are rated up to 2.5 A, enabling direct control of suitable low-voltage loads and interposing circuits.
        • Each energized relay transfers its changeover contact from the rest position to the working position for NO or NC logic.
        • Wiring distribution must keep the combined current of each contact group within the 10 A maximum group rating.
        • A typical 8 ms pickup time should be considered when coordinating relay commands with the surrounding control sequence.
        Description
        6DS1605-8BA provides sixteen electromechanical changeover contacts, allowing each controller command to use either normally open or normally closed logic. Because the contacts are potential-free, the card can interface circuits that cannot share the semiconductor output reference used by other TELEPERM modules.

        A relay typically picks up in 8 ms and releases in 5 ms. Each channel is limited to 2.5 A, the grouped current to 10 A and switching power to 60 W DC, while inductive loads up to the limit require the prescribed external flyback diode.

        Fuses and suppression must be selected from the actual field voltage rather than copied from a neighboring channel. Replacement work should also confirm the terminal contact used—common, NO or NC—because the changeover arrangement can implement inverse logic that is not obvious from the device name.

        Technical notes
        Before transferring wires to 6DS1605-8BA, identify every common/NO/NC conductor and fit suppression for inductive DC loads; swapping contact positions can invert the commanded safe state.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Which contact forms are available on 6DS1605-8BA?
        Every one of the 16 channels is a changeover contact, providing common, normally open and normally closed terminals.
        What is the highest field voltage specified for 6DS1605-8BA?
        The ceiling is 60 V DC or 24 V AC; higher-voltage loads require an external interface.
        How must grouped loading be assessed for 6DS1605-8BA?
        Keep each channel within 2.5 A and the relevant group within 10 A, while also observing switching power and fuse data.
        Why is a flyback diode mentioned for 6DS1605-8BA?
        Inductive DC loads release stored energy when a relay opens; the external diode limits that voltage stress.
        What wiring error is most critical during a 6DS1605-8BA exchange?
        Moving a conductor from NC to NO, or reversing the common assignment, changes the logical safe state even if the relay energizes normally.
        Which relay-contact schedule lets 6DS1605-8BA be quoted without reversing the field logic?
        Provide the label, field voltages, AC/DC load types, steady and inrush currents, contact logic, fuse schedule and quantity.
