Product Description:
The S20-DO-16/1 is a Digital Output Module designed for the IndraControl S20 station. It provides a reliable output of digital signals for automation tasks. This module features short circuit and overload protection.
This S20-DO-16/1 digital output module includes 16 digital outputs and operates with 500 mA per channel. Utilizing an external fuse, the maximum output current that any one device is allowed to have is 8 A. The outputs are compatible with actuators that use a single wire. The nominal ohmic load for each channel is 12 W the inductive load is up to 12 VA (1.2 H), and the lamp load is 12 W. Switching on or off with a minimum needed load of 10 k? results in a signal delay of less than 100 us. The switching frequency of the module can reach up to 10,000 operations per second for standard loads, 1 operation per second for inductive loads, and 16 operations per second for lamp loads. In the event of overload, the module shuts down and restarts automatically. However, inductive overloads can destroy the output. The output voltage in the off state is up to 1 V, and the current is limited to 300 uA. The reverse voltage protection handles pulses up to 0.5 A for 1 second.
The Bosch S20-DO-16/1 digital output module sends error messages for overload or short circuit conditions to the higher level control system. The circuit interruption induces a voltage between - 25.8 V and - 15 V. The short circuit and overload protection of the model are electronic, and shutdown occurs at 0.7 A. If the ground connection is interrupted, off-state output current stays under 1 mA. The device behavior and diagnostics are supported with stored device labels and indicator lights.
Frequently Asked Questions about S20-DO-16/1:
Q: Does the S20-DO-16/1 module handle fast switching applications without delay?
A: Yes, the Bosch S20-DO-16/1 supports switching frequencies up to 10000 operations per second for standard loads. The signal delay remains under 100 us during switching operations.
Q: Will the S20-DO-16/1 digital output module shut down in overload conditions?
A: Yes, the S20-DO-16/1 shuts down automatically during an overload. It restarts itself but inductive overloads can cause permanent output failure.
Q: Can the Bosch S20-DO-16/1 output module protect against reverse pulses?
A: Yes, the module handles reverse voltage pulses up to 0.5 A for 1 second. The off state voltage reaches 1 V with output current limited to 300 uA.
Q: What happens if the ground connection fails in the S20-DO-16/1 module?
A: In that case the off state output current remains below 1 mA. The model behavior remains stable due to built-in diagnostics and indicator lights.
Q: Does the S20-DO-16/1 output module support 1 wire actuator systems?
A: Yes, the Bosch S20-DO-16/1 supports single wire actuator connections on all 16 channels. Each output supports loads like 12 W resistive and 12 VA inductive.
