Overview Manuals Applications Safety Diagnostics & Protection Compliance

Features:

  • Provides sixteen potential-free changeover relay outputs in two groups of eight.
  • Switches 20 to 60 V DC or 24 V AC circuits within the stated contact limits.
  • Includes relay-contact monitoring with a maximum 10 ms test pulse.
The current module is the testable relay-output execution for supported TELEPERM controllers. Each group has a documented 10 A aggregate limit in addition to the per-channel rating.

Controller commands energize the relay coils and present isolated changeover contacts to the field circuits. Contact monitoring helps the system supervise the output path while the board remains installed.

Check voltage class, fuse selection, group loading and load response to test pulses. Inductive DC circuits need the required flyback diode and must remain within the specified switching power.

Legacy availability is reviewed against the TELEPERM system type, output load and complete article number.

  • Switches isolated discrete loads in TELEPERM AS 220 and AS 235 control installations.
  • Drives annunciators, interposing relays and supported actuators through potential-free contacts.
  • Provides testable relay outputs where contact-path supervision is required by the control design.
  • Field sources must be isolated separately because relay contacts can remain energized when module power is off.
  • Group loading must stay below 10 A for channels 1-8 and independently below 10 A for channels 9-16.
  • Inductive DC loads require the specified suppression to limit voltage during relay release.
  • Contact monitoring uses test pulses no longer than 10 ms in the documented operating cycle.
  • A 1 A fast-acting module fuse protects the internal supply path.
  • Channel fuse selection changes with the field-voltage range and must match the official rating.
  • System application is documented for TELEPERM AS 220 E/EHF and AS 235/235H hardware.
  • The double-height Eurocard format and 30 mm front panel must match the installed rack position.
  • Contact ratings and suppression requirements remain part of the approved field-circuit design.
Description
Siemens 6DS1606-8BA is a testable TELEPERM relay output module with sixteen potential-free changeover contacts. The channels are divided into two groups of eight and can switch documented 20 to 60 V DC or 24 V AC loads in AS 220 E/EHF and AS 235/235H control systems. Potential-free contacts allow the field circuits to use their own supported supply arrangement, while the grouped construction keeps the total current and protective devices organized across two independent relay banks.

The module is designed for discrete control duties that require galvanically separated relay contacts, including interposing commands to actuators, alarms and auxiliary circuits. Contact-monitoring test pulses allow the installed system to check the output path, while separate group limits help engineers distribute the connected loads across the two relay banks. Pickup and release times define how quickly each relay follows a command, and the monitoring pulse duration should be considered when the connected device is sensitive to short electrical test signals.

Each channel supports up to 2.5 A continuous current, subject to the 10 A limit for its eight-channel group and the stated switching-power boundary. External flyback protection is required for the documented inductive-load case, and the channel fuses, module fuse, connector assignments and double-height Eurocard format must be checked before installation. Load voltage determines the specified channel-fuse rating, so the field circuit and fuse selection should be reviewed together before the replacement module is energized.

Technical notes
Outputs driven by 6DS1606-8BA may receive a contact-monitoring pulse up to 10 ms; confirm that sensitive loads cannot actuate and fit the specified flyback diode on inductive DC circuits.
