Safety PLC for wireless transmission of signals in SIL3 PL-e certification. Innovative system to eliminate wiring from the machine to the electrical panel by retransmitting 14 I/Os from safety (and non-safety) actuators up to 100 meters away from another module. Diagnostics are on the front panel, and there are two optional relay outputs. Up to 16 modules are usable in the loop in multi-master logic, programmable via wireless dongle, and also for online diagnostics.
