Omron Scientific Technologies has introduced DST1-XD0808SW-1 safety I/O terminals, which support 6 safety inputs and 8 safety outputs and are capable of storing simple logic.
This allows local outputs to be directly controlled by local inputs, giving the user a maximum response time of 18.7 ms, potentially less than 1/6 of the response time for comparable units. The DST1-XD can act as a DeviceNet Slave, allowing safety input and status information to be monitored via a DeviceNet Master. Each safety output can be controlled through a network signal or used as an auxiliary output function. Maintenance functions can measure the number of operations or the operating time for the safety devices.
