FIELD: signaling engineering. ^ SUBSTANCE: device for contact sensor control consist of electromagnetic relay (1), first (2) and second (3) diodes, first (4) and second (5) resistors, switch (6), toggle (7), communications channel (8) with controlled contact sensor (9), bus (10), (13) supply, front contact (12) of electromagnetic relay (1), device outputs (11) and (14). Technical result is achieved by introducing switch (6), toggle (7), two resistors (4) and (5), second diode (3), two (11) and (14) device outputs and new connections between elements. ^ EFFECT: increased functional reliability and extended functional capabilities of the device. ^ 1 dwg |
