Mitsubishi's part number QS90SR2SP-Q represents a safety relay module tailored for use in PLC configurations. It contains one channel for safety input, which effectively uses two inputs for enhanced functionality. In addition, there is a dedicated start-up input designed to ensure safe operation during system initiation. This relay module accepts a safety input voltage ranging from 20.4VDC to 26.4VDC, with specific performance requirements regarding the ripple factor, which should not exceed 5%.
Safety input current for this device is rated at 4.6mA, while initial surge conditions upon relay activation can reach up to 300mA. For safety outputs, the QS90SR2SP-Q has one dedicated channel that provides three outputs, capable of handling a maximum voltage rating of 250VAC or 30VDC.
The relay also has a notable operational capability, with a minimum switchable load of 5VDC/5mA. It can handle up to 1,200 switching operations per hour, indicating robust performance for dynamic control applications. Response times are quick, with the output activating within ≤50 milliseconds when the safety input is turned on and deactivating within ≤20 milliseconds when off.
Furthermore, this safety relay module supports adding up to three extension modules, which enhances its versatility in various setups. The internal power consumption remains low, rated at merely 0.09A on a 5VDC supply. The operational temperature range is designed between 0°C and 55°C, making it suitable for a variety of environmental conditions.
