Product Description:
The S20-DO-16/3 digital output module from Bosch Indramat is made for use in modular I/O systems. The module operates on a nominal output voltage of 24 V DC and supports 16 digital outputs. It is designed to accommodate a variety of output requirements in industrial automation applications.
A maximum output current of 500 mA per channel is supported by the S20-DO-16/3 output module. The nominal load of 12 W on the output channels is equivalent to a resistance of 48 ohms at the nominal voltage. The utmost permissible voltage range is 19.2 V DC to 30 V DC. The product is equipped with polarity reversal protection that employs a parallel diode and necessitates an external 5 A fuse during initialization. This fuse can be replaced with an 8 A fuse for standard operation. Overcurrent termination occurs when the current exceeds 0.7 A. When the discharge current is at least 50 mA, the signal delay is less than 100 us. With an inductive load, the switching frequency is restricted to one operation per second. The dimensions are 53.6 mm in width, 129.9 mm in height, and 54 mm in depth. The bus interface of the module can support a transmission speed of 100 MBit/s.
The S20-DO-16/3 digital output module can lose its output when it is overloaded with induction current. It is made to meet the requirements of IEC 61140, EN 61140, and VDE 0140-1 for Protection Class III. The module has a weight of 234 g. It has a level of safety called IP20. It is estimated that up to 240 watts of power will be used at the output voltage. The least amount of load resistance is 10 k?. The module has electronic surge safety that is only supposed to work for half a second at 35 V.
Frequently Asked Questions about S20-DO-16/3:
Q: Why does S20-DO-16/3 support a 10 k? minimum load?
A: It ensures stable operation and accurate output detection. This resistance prevents false triggering and allows a better response from the output module.
Q: Does S20-DO-16/3 have fast signal switching?
A: Yes, signal delay is under 100 us. It supports fast control operations with minimum latency under sufficient load current conditions.
Q: Why does S20-DO-16/3 include 35 V surge protection?
A: The surge protection absorbs transient voltage spikes. It protects internal circuitry and maintains output reliability under voltage fluctuations.
Q: How does S20-DO-16/3 handle inductive loads?
A: It allows one switching cycle per second. Inductive overloads can destroy the output, so usage is limited under such conditions.
Q: Do S20-DO-16/3 outputs support overcurrent shutdown?
A: Yes, it activates when the current exceeds 0.7 A. This helps prevent thermal overload and safeguards the connected devices.
