This figure represents the current flow in a safety-mat connected to safety inputs:
(A): Current source
(A1): 24 Vdc
(A2): GND pin out
(B): Outputs
(1): Current flow when the mat is released, relays K1 and K2 are supplied.
(2): Current flow when the mat is under pressure (mat is stepped on), relays K1 and K2 are not supplied (the mat provides a short circuit path).
